This demo uses angular-ui-grid to display a data table. The ui-grid does not
provide any way to hook into the import button, so the demo includes a simple
provide any way to modify the import button, so the demo includes a simple
directive for a HTML File Input control. It also includes a sample service for
export which adds an item to the export menu.
## Import Directive
`SheetJSImportDirective` follows the prescription from the README for File input
controls using `readAsBinaryString`, converting to a suitable representation
and updating the scope.
A general import directive is fairly straightforward:
- Define the `importSheetJs` directive in the app:
```js
app.directive("importSheetJs", [SheetJSImportDirective]);
```
- Add the attribute `import-sheet-js=""` to the file input element:
```html
<input type="file" import-sheet-js="" multiple="false" />
```
- Define the directive:
```js
var SheetJSImportDirective = function() {
return {
scope: { },
link: function ($scope, $elm, $attrs) {
$elm.on('change', function (changeEvent) {
var reader = new FileReader();
reader.onload = function (e) {
/* read workbook */
var bstr = e.target.result;
var workbook = XLSX.read(bstr, {type:'binary'});
/* DO SOMETHING WITH workbook HERE */
};
reader.readAsBinaryString(changeEvent.target.files[0]);
});
}
};
};
```
The demo `SheetJSImportDirective` follows the prescription from the README for
File input controls using `readAsBinaryString`, converting to a suitable
representation and updating the scope.
## Export Service
An export can be triggered at any point! Depending on how data is represented,
a workbook object can be built using the utility functions. For example, using
an array of objects:
```js
/* starting from this data */
var data = [
{ name: "Barack Obama", pres: 44 },
{ name: "Donald Trump", pres: 45 }
];
/* generate a worksheet */
var ws = XLSX.utils.json_to_sheet(data);
/* add to workbook */
var wb = XLSX.utils.book_new();
XLSX.utils.book_append_sheet(wb, ws, "Presidents");
/* write workbook (use type 'binary') */
var wbout = XLSX.write(wb, {bookType:'xlsx', type:'binary'});
/* generate a download */
function s2ab(s) {
var buf = new ArrayBuffer(s.length);
var view = new Uint8Array(buf);
for (var i=0; i!=s.length; ++i) view[i] = s.charCodeAt(i) & 0xFF;
return buf;
}
saveAs(new Blob([s2ab(wbout)],{type:"application/octet-stream"}), "sheetjs.xlsx");
```
`SheetJSExportService` exposes export functions for `XLSB` and `XLSX`. Other
formats are easily supported by changing the `bookType` variable. It grabs
values from the grid, builds an array of arrays, generates a workbook and uses
FileSaver to generate a download. By setting the `filename` and `sheetname`
options in the ui-grid options, the output can be controlled.

@ -10,6 +10,61 @@ This demo uses an array of arrays (type `Array<Array<any>>`) as the core state.
The component template includes a file input element, a table that updates with
the data, and a button to export the data.
## Array of Arrays
`Array<Array<any>>` neatly maps to a table with `ngFor`:
```html
<table class="sjs-table">
<tr *ngFor="let row of data">
<td *ngFor="let val of row">
{{val}}
</td>
</tr>
</table>
```
The `aoa_to_sheet` utility function returns a worksheet. Exporting is simple:
```typescript
/* generate worksheet */
const ws: XLSX.WorkSheet = XLSX.utils.aoa_to_sheet(this.data);
/* generate workbook and add the worksheet */
const wb: XLSX.WorkBook = XLSX.utils.book_new();
XLSX.utils.book_append_sheet(wb, ws, 'Sheet1');
/* save to file */
const wbout: string = XLSX.write(wb, { bookType: 'xlsx', type: 'binary' });
saveAs(new Blob([s2ab(wbout)]), 'SheetJS.xlsx');
```
`sheet_to_json` with the option `header:1` makes importing simple:
```typescript
/* <input type="file" (change)="onFileChange($event)" multiple="false" /> */
/* ... (within the component class definition) ... */
onFileChange(evt: any) {
/* wire up file reader */
const target: DataTransfer = <DataTransfer>(evt.target);
if (target.files.length !== 1) throw new Error('Cannot use multiple files');
const reader: FileReader = new FileReader();
reader.onload = (e: any) => {
/* read workbook */
const bstr: string = e.target.result;
const wb: XLSX.WorkBook = XLSX.read(bstr, {type: 'binary'});
/* grab first sheet */
const wsname: string = wb.SheetNames[0];
const ws: XLSX.WorkSheet = wb.Sheets[wsname];
/* save data */
this.data = <AOA>(XLSX.utils.sheet_to_json(ws, {header: 1}));
};
reader.readAsBinaryString(target.files[0]);

code to access the library with `var XLSX = require('xlsx')`. The JS code from
the root demo was moved to a separate `app.js` script. That script is bundled:
```bash
browserify app.js > browserify.js
uglifyjs browserify.js > browserify.min.js
```
### Worker Scripts
Browserify can also bundle worker scripts! Instead of using `importScripts`,
the worker script should require the module:
```diff
-importScripts('dist/xlsx.full.min.js');
+var XLSX = require('xlsx');
```
The same process generates the worker script:
```bash
browserify xlsxworker.js > worker.js
uglifyjs worker.js > worker.min.js

be used in any reasonably compliant JS implementation. It should play nice with
meteor out of the box.
Using the npm module, the library can be imported from client or server side:
```js
import XLSX from 'xlsx'
```
All of the functions and utilities are available in both realms. Since the core
data representations are simple JS objects, the workbook object can be passed on
the wire, enabling hybrid workflows where the server processes data and client
finishes the work.
## This demonstration
You can split the work between the client and server side as you see fit. The
obvious extremes of pure-client code and pure-server code are straightforward.
This demo tries to split the work to demonstrate that the workbook object can be
passed on the wire.
Note: the obvious extremes of pure-client code and pure-server code are covered
in other demos.
The read demo:
### Reading Data
The parse demo:
- accepts files from the client side
- sends binary string to server
- processes data on server side
- sends workbook object to client
- renders HTML and adds to a DOM element
The write demo:
- generates workbook on server side
- sends workbook object to client
- generates file on client side
- triggers a download.
The logic from within the `FileReader` is split as follows:
This demo uses the FileSaver.js library for writing files, installed through the
[`pfafman:filesaver` wrapper](https://atmospherejs.com/pfafman/filesaver):
```bash
meteor add pfafman:filesaver
```js
// CLIENT SIDE
const bstr = e.target.result;
// SERVER SIDE
const wb = XLSX.read(bstr, { type: 'binary' });
// CLIENT SIDE
const ws = wb.Sheets[wb.SheetNames[0]];
const html = XLSX.utils.sheet_to_html(ws, { editable: true });
document.getElementById('out').innerHTML = html;
```
### Writing Data
The write demo:
- grabs HTML from the client side
- sends HTML string to server
- processes data on server side
- sends workbook object to client
- generates file on client side and triggers a download
The logic from within the `click` event is split as follows:
```js
// CLIENT SIDE
const html = document.getElementById('out').innerHTML;
// SERVER SIDE
const wb = XLSX.read(html, { type: 'binary' });
// CLIENT SIDE
const o = XLSX.write(wb, { bookType: 'xlsx', type: 'binary' });
saveAs(new Blob([s2ab(o)], {type:'application/octet-stream'}), 'sheetjs.xlsx');

This library is compatible with NW.js and should just work out of the box.
The demonstration uses NW.js 0.24 with the dist script.
The standard HTML5 `FileReader` techniques from the browser apply to NW.js.
## Reading data
The standard HTML5 `FileReader` techniques from the browser apply to NW.js!
This demo includes a drag-and-drop box as well as a file input box, mirroring
the [SheetJS Data Preview Live Demo](http://oss.sheetjs.com/js-xlsx/)
the [SheetJS Data Preview Live Demo](http://oss.sheetjs.com/js-xlsx/).
## Writing data
File input elements with the attribute `nwsaveas` show UI for saving a file. The
standard trick is to generate a hidden file input DOM element and "click" it.
Since NW.js does not present a `writeFileSync` in the `fs` package, a manual
step is required:
```js
/* from within the input change callback, `this.value` is the file name */
var filename = this.value, bookType = (filename.match(/[^\.]*$/)||["xlsx"])[0];
/* convert the TABLE element back to a workbook */
var wb = XLSX.utils.table_to_book(HTMLOUT);
/* write to buffer */
var wbout = XLSX.write(wb, {type:'buffer', bookType:bookType});
/* use the async fs.writeFile to save the data */
fs.writeFile(filename, wbout, function(err) {
if(!err) return alert("Saved to " + filename);
alert("Error: " + (err.message || err));
});
```

## Other Demos
#### Preact
`preact-compat` is an easy-to-use compatibility layer that provides equivalents
for `React` and `ReactDOM`. The `preact` demo uses the same JSX component code!
[The docs](https://npm.im/preact-compat#use-without-webpackbrowserify) explain
how to convert the in-browser React demo to Preact.
#### Server-Rendered React Components with Next.js
The demo uses the same component code as the in-browser version, but the build
step adds a small header that imports the library. The import is not needed in
deployments that use script tags to include the library.

The minified dist files trip up the RequireJS mechanism. To bypass, the scripts
automatically expose an `XLSX` variable that can be used if the require callback
argument is `_XLSX` rather than `XLSX`:
argument is `_XLSX` rather than `XLSX`. This trick is employed in the included
`xlsx-shim.js` script:
```js
require(["xlsx.full.min"], function(_XLSX) { /* ... */ });
/* xlsx-shim.js */
define(['xlsx'], function (_XLSX) {
return XLSX;
});
```
This demo uses the `r.js` optimizer to build a source file.
The require config should set `xlsx` path to the appropriate dist file:
```js
paths: {
xlsx: "xlsx.full.min"
},
```
Once that is set, app code can freely require `"xlsx-shim"`:
```js
require(["xlsx-shim"], function(XLSX) {
/* use XLSX here */
});
```
## Deployments
`browser.html` demonstrates a dynamic deployment, using the in-browser config:
```html
<script src="require.js"></script>
<script>
require.config({
baseUrl: ".",
name: "app",
paths: {
xlsx: "xlsx.full.min"
}
});
</script>
<script src="app.js"></script>
```
`optimizer.html` demonstrates an optimized deployment using `build.js` config:
```js
/* build config */
({
baseUrl: ".",
name: "app",
paths: {
xlsx: "xlsx.full.min"
},
out: "app-built.js"
})
```
The optimizer is invoked with:
```bash
node r.js -o build.js paths.requireLib=./require include=requireLib
```
That step creates a file `app-built.js` that can be included in a page:
```html
<!-- final bundle includes require.js, xlsx-shim, library and app code -->
<script src="app-built.js"></script>
```

```js
/* main worker script */
importScripts('system.js');
SystemJS.config({ /* ... browser config ... */ });
onmessage = function(evt) {
SystemJS.import('xlsxworker.js').then(function() { _cb(evt); });
};

var XLSX = require('xlsx');
_cb = function (evt) { /* ... do work here ... */ };

# VueJS 2
The `xlsx.core.min.js` and `xlsx.full.min.js` scripts are designed to be dropped
into web pages with script tags e.g.
into web pages with script tags:
```html
<script src="xlsx.full.min.js"></script>
```
Strictly speaking, there should be no need for a Vue.JS demo! You can proceed
as you would with any other browser-friendly library.
The library can also be imported directly from single-file components with:
```js
import XLSX from 'xlsx';
```
This demo directly generates HTML using `sheet_to_html` and adds an element to
a pregenerated template. It also has a button for exporting as XLSX.
a pre-generated template. It also has a button for exporting as XLSX.
Other scripts in this demo show:
- server-rendered VueJS component (with `nuxt.js`)
- `weex` deployment for iOS
## Single File Components
## Internal State
For Single File Components, a simple `import XLSX from 'xlsx'` should suffice.
The webpack demo includes a sample `webpack.config.js`.
The plain JS demo embeds state in the DOM. Other demos use proper state.
The simplest state representation is an array of arrays. To avoid having the
table component depend on the library, the column labels are precomputed. The
state in this demo is shaped like the following object:
```js
{
cols: [{ name: "A", key: 0 }, { name: "B", key: 1 }, { name: "C", key: 2 }],
data: [
[ "id", "name", "value" ],
[ 1, "sheetjs", 7262 ]
[ 2, "js-xlsx", 6969 ]
]
}
```
`sheet_to_json` and `aoa_to_sheet` utility functions can convert between arrays
of arrays and worksheets:
```js
/* convert from workbook to array of arrays */
var first_worksheet = workbook.Sheets[workbook.SheetNames[0]];
var data = XLSX.utils.sheet_to_json(first_worksheet, {header:1});
/* convert from array of arrays to workbook */
var worksheet = XLSX.utils.aoa_to_sheet(data);
var new_workbook = XLSX.utils.book_new();
XLSX.utils.book_append_sheet(new_workbook, worksheet, "SheetJS");
```
The column objects can be generated with the `encode_col` utility function:
```js
function make_cols(refstr/*:string*/) {
var o = [];
var range = XLSX.utils.decode_range(refstr);
for(var i = 0; i <= range.e.c; ++i) {
o.push({name: XLSX.utils.encode_col(i), key:i});
}
return o;
}
```
## WeeX
<img src="screen.png" width="400px"/>
Reproducing the full project is a little bit tricky. The included `weex.sh`
script performs the necessary installation steps.
WeeX is a framework for building real mobile apps, akin to React Native. The
ecosystem is not quite as mature as React Native, missing basic features like
document access. As a result, this demo uses the `stream.fetch` API to upload
Base64-encoded documents to <https://hastebin.com> and download a precomputed
[Base64-encoded workbook](http://sheetjs.com/sheetjs.xlsx.b64).
Using NodeJS it is straightforward to convert to/from base64:

fs.writeFileSync("sheetjs.xls", new Buffer(str, "base64"));
```
## Nuxt and State
## Other Demos
The `nuxt.js` demo uses the same state approach as the React next.js demo:
```js
{
cols: [
{ name: "A", key: 0 },
{ name: "B", key: 1 },
{ name: "C", key: 2 },
],
data: [

[ 1, "sheetjs", 7262 ]
[ 2, "js-xlsx", 6969 ]
]
}
```

be explicitly included in the layout HTML (as script tag) and in the component:

```
## Other Demos
This demo also attempts to demonstrate bundling of the library as well as the
core and full distribution versions. `app.js` is the common app code (it will
not be bundled). The individual bundles merely wrap and reflect `XLSX`. The
app code uses the bundles with script tag inclusion in the main HTML files. The
worker scripts use the bundles with `importScripts` references.
| required script | HTML page | entry | worker script |
|----------------:|------------:|----------:|----------------:|
| main `xlsx` lib | `main.html` | `main.js` | `mainworker.js` |
| `xlsx.core.min` | `core.html` | `core.js` | `coreworker.js` |
| `xlsx.full.min` | `full.html` | `full.js` | `fullworker.js` |
The entry points in the demo merely require and re-export the library:
```js
/* main.js */
var XLSX = require('../../');
console.log("it works!");
module.exports = XLSX;
```
The main advantage of reflecting the library is deduplication: the library code
is only downloaded once. The basic example builds a separate worker script and
eventually ships the library twice.
### Reflecting the XLSX variable
This library will not assign to `module.exports` if it is run in the browser. To
convince webpack, the demo webpack config sets `output`:
```js
output: {
libraryTarget: 'var',
library: 'XLSX'
}

@ -5,7 +5,20 @@ web browser clients and web servers. Since this library works in web browsers,
server conversion work can be offloaded to the client! This demo shows a few
common scenarios involving browser APIs and popular wrapper libraries.
## Sample Server
## Demos
The included demos focus on an editable table. There are two separate flows:
- When the page is accessed, the browser will attempt to download `sheetjs.xlsx`
and read the workbook. The old table will be replaced with an editable table
whose contents match the first worksheet. The table is generated using the
`sheet_to_html` utility with `editable:true` option
- When the upload button is clicked, the browser will generate a new worksheet
using `table_to_book` and build up a new workbook. It will then attempt to
generate a Base64-encoded XLSX string and upload it to the server.
### Demo Server
The `server.js` nodejs server serves static files on `GET` request. On a `POST`
request to `/upload`, the server processes the body and looks for the `file` and

axios and superagent patterns are similar to the XMLHttpRequest pattern but
involve much less boilerplate:
### superagent Wrapper Library
The `superagent` library usage mirrors XHR:
```js
/* set up an async GET request with superagent */
superagent.get(url).responseType('arraybuffer').end(function(err, res) {
/* parse the data when it is received */
var data = new Uint8Array(res.body);
var workbook = XLSX.read(data, {type:"array"});
/* DO SOMETHING WITH workbook HERE */
});
```
The upload portion only differs in the actual request command:
```js
/* send data (fd is the FormData object) */
superagent.post("/upload").send(fd);
```
### superagent Wrapper Library
The `axios` library presents a Promise interface. The axios demo uses a single
promise, but for production deployments it may make sense to separate parsing:
```js
/* set up an async GET request with axios */
axios(url, {responseType:'arraybuffer'}).then(function(res) {
/* parse the data when it is received */
var data = new Uint8Array(res.data);
var workbook = XLSX.read(data, {type:"array"});
/* DO SOMETHING WITH workbook HERE */
axios(url, {responseType:'arraybuffer'}).catch(function(err) {
/* error in getting data */
}).then(function(res) {
/* parse the data when it is received */
var data = new Uint8Array(res.data);
var workbook = XLSX.read(data, {type:"array"});
return workbook;
}).catch(function(err) {
/* error in parsing */
}).then(function(workbook) {
/* DO SOMETHING WITH workbook HERE */
});
```
/* set up an async GET request with superagent */
superagent.get(url).responseType('arraybuffer').end(function(err, res) {
/* parse the data when it is received */
var data = new Uint8Array(res.body);
var workbook = XLSX.read(data, {type:"array"});
/* DO SOMETHING WITH workbook HERE */
});
The upload portion only differs in the actual request command:
```js
/* send data (fd is the FormData object) */
axios("/upload", {method: "POST", data: fd});
```
