## Goja
Goja is a pure Go implementation of ECMAScript 5. As of this writing, there are
some issues with processing Unicode data, but the `xlsx.core.min.js` script can
be processed. `[]byte` should be transformed to a binary string in the engine:
```go
/* read file */
data, _ := ioutil.ReadFile("sheetjs.xlsx")
/* load into engine */
vm.Set("buf", data)
/* convert to binary string */
_, _ = vm.RunString("var bstr = ''; for(var i = 0; i < buf.length; ++i) bstr += String.fromCharCode(buf[i]);")
/* parse */
wb, _ = vm.RunString("wb = XLSX.read(bstr, {type:'binary', cellNF:true});")
```
On the write side, `"base64"` strings can be decoded in Go:
```go
b64str, _ := vm.RunString("XLSX.write(wb, {type:'base64', bookType:'xlsx'})")
buf, _ := base64.StdEncoding.DecodeString(b64str.String())
_ = ioutil.WriteFile("sheetjs.xlsx", buf, 0644)
```

## NativeScript
Reproducing the full project is a little bit tricky. The included `nscript.sh`
script performs the necessary installation steps and adds the necessary shims
for `async` support. Due to incompatibilities with NativeScript and TypeScript
definitions, apps should require the `xlsx.full.min.js` file directly:
```typescript
const XLSX = require("./xlsx.full.min.js");
```
The `ISO_8859_1` encoding from the text module specifies `"binary"` strings.
`fs.File#readText` and `fs.File#writeText` reads and writes files:
```typescript
/* read a workbook */
const bstr: string = await file.readText(textModule.encoding.ISO_8859_1);
const wb = XLSX.read(bstr, { type: "binary" });
/* write a workbook */
const wbout: string = XLSX.write(wb, { bookType: 'xlsx', type: 'binary' });
await file.writeText(wbout, textModule.encoding.ISO_8859_1);
```

# Chrome and Chromium
This library is compatible with Chrome and Chromium extensions and should just
work out of the box. Specific API support is listed in the Chrome extensions
API documentation.
## Generating Downloads
The `writeFile` function works in a Chrome or Chromium extension:
```js
XLSX.writeFile(wb, "export.xlsx");
```
Under the hood, it uses the `chrome.downloads` API. `"downloads"` permission
should be set in `manifest.json`:
```js
"permissions": [
"downloads"
]
```
## Content Script Table Scraping
`table_to_book` and `table_to_sheet` can help build workbooks from DOM tables:
```js
var tables = document.getElementsByTagName("table");
var wb = XLSX.utils.book_new();
for(var i = 0; i < tables.length; ++i) {
var ws = XLSX.utils.table_to_sheet(tables[i]);
XLSX.utils.book_append_sheet(wb, ws, "Table" + i);
}
```
## Demo
The demo extension includes multiple features to demonstrate sample usage.
Production extensions should include proper error handling.
#### Table Exporter
The `content.js` content script converts a table in the DOM to workbook object
using the `table_to_book` utility function:
```js
// event page script trigger
chrome.tabs.sendMessage(tab.id);
// content script convert
var wb = XLSX.utils.table_to_book(elt);
// event page script callback
XLSX.writeFile(wb, "export.xlsx");
```
Since the workbook object is a plain JS object, the object is sent back to an
event page script which generates the file and attempts a download.
#### Bookmark Exporter
`chrome.bookmarks` API enables bookmark tree traversal. The "Export Bookmarks"
button in the extension pop-up recursively walks the bookmark tree, pushes the
bookmark URLs into a data array, and exports into a simple spreadsheet:
```js
/* walk the bookmark tree */
function recurse_bookmarks(data, tree) {
if(tree.url) data.push({Name: tree.title, Location: tree.url});
(tree.children||[]).forEach(function(child) { recurse_bookmarks(data, child); });
}
/* get bookmark data */
chrome.bookmarks.getTree(function(res) {
/* load into an array */
var data = [];
res.forEach(function(t) { recurse_bookmarks(data, t); });
/* create worksheet */
var ws = XLSX.utils.json_to_sheet(data, { header: ['Name', 'Location'] });
/* create workbook and export */
var wb = XLSX.utils.book_new();
XLSX.utils.book_append_sheet(wb, ws, 'Bookmarks');
XLSX.writeFile(wb, "bookmarks.xlsx");
});
```

@ -296,5 +296,45 @@ LowDB is a small schemaless database powered by `lodash`. `_.get` and `_.set`
helper functions make storing metadata a breeze. The included `SheetJSLowDB.js`
script demonstrates a simple adapter that can load and dump data.
### Document Databases
Since document databases are capable of holding more complex objects, they can
actually hold the underlying worksheet objects! In some cases, where arrays are
supported, they can even hold the workbook object.
#### MongoDB
MongoDB is a popular document-oriented database engine. `MongoDBTest.js` uses
MongoDB to hold a simple workbook and export to XLSX.
`MongoDBCRUD.js` follows the SQL examples using an idiomatic collection
structure. Exporting and importing collections are straightforward:
<details>
<summary><b>Example code</b> (click to show)</summary>
```js
/* generate a worksheet from a collection */
const aoa = await db.collection('coll').find({}).toArray();
aoa.forEach((x) => delete x._id);
const ws = XLSX.utils.json_to_sheet(aoa);
/* import data from a worksheet to a collection */
const aoa = XLSX.utils.sheet_to_json(ws);
await db.collection('coll').insertMany(aoa, {ordered: true});
```
#### Firebase
[`firebase-server`](https://www.npmjs.com/package/firebase-server) is a simple
mock Firebase server used in the tests, but the same code works in an external
Firebase deployment when plugging in the database connection info.
`FirebaseDemo.html` and `FirebaseTest.js` demonstrate a whole-workbook process.
The entire workbook object is persisted, a few cells are changed, and the stored
data is dumped and exported to XLSX.

# "Serverless" Functions
Because the library is pure JS, the hard work of reading and writing files can
be performed in the client browser or on the server side. On the server side,
the mechanical process is essentially independent from the data parsing or
generation. As a result, it is sometimes sensible to organize applications so
that the "last mile" conversion between JSON data and spreadsheet files is
independent from the main application.
The most obvious architecture would split off the JSON data conversion as a
separate microservice or application. Since it is only needed when an import or
export is requested, and since the process itself is relatively independent from
the rest of a typical service, a "Serverless" architecture makes a great fit.
Since the "function" is separate from the rest of the application, it is easy to
integrate into a platform built in Java or Go or Python or another language!
This demo discusses general architectures and provides examples for popular
commercial systems and self-hosted alternatives. The examples are merely
intended to demonstrate very basic functionality.
## Simple Strategies
#### Data Normalization
Most programming languages and platforms can process CSV or JSON but can't use
XLS or XLSX or XLSB directly. Form data from an HTTP POST request can be parsed
and contained files can be converted to CSV or JSON. The `XLSX.stream.to_csv`
utility can stream rows to a standard HTTP response. `XLSX.utils.sheet_to_json`
can generate an array of objects that can be fed to another service.
At the simplest level, a file on the filesystem can be converted using the bin
script that ships with the `npm` module:
```bash
$ xlsx /path/to/uploads/file > /tmp/new_csv_file
```
From a utility script, workbooks can be converted in two lines:
```js
var workbook = XLSX.readFile("path/to/file.xlsb");
XLSX.writeFile(workbook, "output/path/file.csv");
```
The `mcstream.js` demo uses the `microcule` framework to show a simple body
converter. It accepts raw data from a POST connection, parses as a workbook,
and streams back the first worksheet as CSV:
<details>
<summary><b>Code Sketch</b> (click to show)</summary>
```js
const XLSX = require('xlsx');
module.exports = (hook) => {
/* process_RS from the main README under "Streaming Read" section */
process_RS(hook.req, (wb) => {
hook.res.writeHead(200, { 'Content-Type': 'text/csv' });
/* get first worksheet */
const ws = wb.Sheets[wb.SheetNames[0]];
/* generate CSV stream and pipe to response */
const stream = XLSX.stream.to_csv(ws);
stream.pipe(hook.res);
});
};
```
</details>
#### Report Generation
For an existing platform that already generates JSON or CSV or HTML output, it
is very easy to embellish output in an Excel-friendly XLSX file. The
`XLSX.utils.sheet_add_json` and `XLSX.utils.sheet_add_aoa` functions can add
data rows to an existing worksheet:
```js
var ws = XLSX.utils.aoa_to_sheet([
["Company Report"],
[],
["Item", "Cost"]
]);
XLSX.utils.sheet_add_json(ws, [
{ item: "Coffee", cost: 5 },
{ item: "Cake", cost: 20 }
], { skipHeader: true, origin: -1, header: ["item", "cost"] });
```
## Deployment Targets
The library is supported in Node versions starting from `0.8` as well as a
myriad of ES3 and ES5 compatible JS engines. All major services use Node
versions beyond major release 4, so there should be no problem directly using
the library in those environments.
Note that most cloud providers proactively convert form data to UTF8 strings.
This is especially problematic when dealing with XLSX and XLSB files, as they
naturally contain codes that are not valid UTF8 characters. As a result, these
demos specifically handle Base64-encoded files only. To test on the command
line, use the `base64` tool to encode data before piping to `curl`:
```
base64 test.xlsb | curl -F "data=@-;filename=test.xlsb" http://localhost/
```
#### AWS Lambda
Through the AWS Gateway API, Lambda functions can be triggered on HTTP requests.
The `LambdaProxy` example reads files from form data and converts to CSV.
When deploying on AWS, be sure to `npm install` locally and include the modules
in the ZIP file.
#### Azure Functions
Azure supports many types of triggers. The `AzureHTTPTrigger` shows an example
HTTP trigger that converts the submitted file to CSV.
When deploying on Azure, be sure to install the module from the remote console,
as described in the "Azure Functions JavaScript developer guide".
