## Lume
|
||||
|
||||
Lume is a static site generator for the Deno platform.
|
||||
|
||||
`lume#loadData` can add custom loaders for data. The loader method receives a
|
||||
path to the file, which can be read with `XLSX.readFile`. This should be added
|
||||
to `_config.js`, like in the example below:
|
||||
|
||||
```js title="_config.js"
|
||||
import lume from "lume/mod.ts";
|
||||
import { readFile, utils } from 'https://cdn.sheetjs.com/xlsx-latest/package/xlsx.mjs';
|
||||
|
||||
function wbLoader(path) {
|
||||
const wb = readFile(path);
|
||||
const res = wb.SheetNames.map(n => ({
|
||||
name: n,
|
||||
data: utils.sheet_to_json(wb.Sheets[n])
|
||||
}));
|
||||
return { data: res };
|
||||
}
|
||||
|
||||
const site = lume();
|
||||
const exts = [".xlsx", ".numbers", /* ... other supported extensions */];
|
||||
// highlight-next-line
|
||||
site.loadData(exts, wbLoader);
|
||||
|
||||
export default site;
|
||||
```
|
||||
|
||||
The actual spreadsheets should be placed in the `_data` subfolder.
|
||||
|
||||
The variable name is the stem of the filename (`sheetjs` if `sheetjs.xlsx` or
|
||||
`sheetjs.numbers` exists). A Nunjucks or JSX template can loop through the
|
||||
worksheets and the data rows. The example assumes each worksheet has a `name` and `index` column:
|
||||
|
||||
```jsx title="index.jsx"
|
||||
export default ({sheetjs}) => {
|
||||
return (<>{(sheetjs.data).map(sheet => (<>

Reading and writing files require native support. `readFile` and `writeFile`
|
||||
include support for some approaches but do not support every API. When an API
|
||||
is not supported by `readFile` or `writeFile`, the underlying `read` and
|
||||
`write` methods can be used.
|
||||
|
||||
This demo looks at various web APIs. More specific approaches for deployments
|
||||
like mobile apps are covered in their respective demos.
|
||||
|
||||
:::note
|
||||
|
||||
Some snippets are also available in the "Common Use Cases" section:

||||

|
||||
|
||||
:::
|
||||
|
||||
:::warning
|
||||
|
||||
Not all web APIs are supported in all browsers. For example, Firefox does not
|
||||
support the "File System Access API".
|
||||
|
||||
Even when a browser technically supports a web API, it may be disabled in the
|
||||
client browser. Some APIs do not give any feedback.
|
||||
|
||||
:::
|
||||
|
||||
## Binary Data
|
||||
|
||||
Modern browser APIs typically use typed arrays or `Blob` or `File` structures.
|
||||
|
||||
_Reading Binary Data_
|
||||
|
||||
Given a `Blob` or `File`, the underlying data cannot be read synchronously!
|
||||
|
||||
The callback-based approach uses a `FileReader`:
|
||||
|
||||
```js
|
||||
const reader = new FileReader();
|
||||
reader.onload = function(e) {
|
||||
/* e.target.result is an ArrayBuffer */
|
||||
const wb = XLSX.read(e.target.result);
|
||||
console.log(XLSX.utils.sheet_to_csv(wb.Sheets[wb.SheetNames[0]]));
|
||||
}
|
||||
reader.readAsArrayBuffer(file);
|
||||
```
|
||||
|
||||
The Promise-based approach uses `Blob#arrayBuffer`:
|
||||
|
||||
```js
|
||||
// usage: const wb = await blob_to_wb(blob);
|
||||
async function blob_to_wb(blob) {
|
||||
return XLSX.read(await blob.arrayBuffer());
|
||||
}
|
||||
```
|
||||
|
||||
_Writing Binary Data_
|
||||
|
||||
`XLSX.write` can generate `Uint8Array` results by passing `type: "buffer"`. A
|
||||
`Blob` can be created by using the constructor:
|
||||
|
||||
```js
|
||||
const u8 = XLSX.write(workbook, { type: "buffer", bookType: "xlsx" });
|
||||
const blob = new Blob([u8], { type: "application/vnd.ms-excel" });
|
||||
```
|
||||
|
||||
## Web Workers
|
||||
|
||||
:::warning
|
||||
|
||||
**None of the browser methods work from Web Worker contexts!**
|
||||
|
||||
Data operations with the Web APIs must happen in the browser main thread.
|
||||
|
||||
:::
|
||||
|
||||
Web Workers and main thread can transfer `ArrayBuffer` or `Uint8Array` objects.
|
||||
|
||||
When generating a file, the worker will call `XLSX.write` with type `buffer`
|
||||
and transfer the result to the main thread to initiate a download.
|
||||
|
||||
When parsing a file, the main thread will use the web API to read a `File` or
|
||||
`Blob`, extract the underlying `ArrayBuffer` and transfer to the Web Worker.
|
||||
|
||||
## HTML5 Download Attribute
|
||||
|
||||
_Writing Files_
|
||||
|
||||
`writeFile` will attempt a download in the browser using the attribute.
|
||||
|
||||
```js
|
||||
XLSX.writeFile(wb, "SheetJS.xlsx");
|
||||
```
|
||||
|
||||
## File API
|
||||
|
||||
_Reading Files_
|
||||
|
||||
In the `change` event of `<input type="file">`, `target` hold a list of files:
|
||||
|
||||
```js
|
||||
async function handleFileAsync(e) {
|
||||
/* get first file */
|
||||
const file = e.target.files[0];
|
||||
/* get raw data */
|
||||
const data = await file.arrayBuffer();
|
||||
/* data is an ArrayBuffer */
|
||||
const workbook = XLSX.read(data);
|
||||
/* do something with the workbook here */
|
||||
console.log(XLSX.utils.sheet_to_json(wb.Sheets[wb.SheetNames[0]]))
|
||||
}
|
||||
input_dom_element.addEventListener("change", handleFileAsync, false);
|
||||
```
|
||||
|
||||
## HTML Drag and Drop API
|
||||
|
||||
_Reading Files_
|
||||
|
||||
The `dataTransfer` property of the `drop` event holds a list of files:
|
||||
|
||||
```js
|
||||
async function handleDropAsync(e) {
|
||||
e.stopPropagation(); e.preventDefault();
|
||||
/* get first file */
|
||||
const f = e.dataTransfer.files[0];
|
||||
/* get raw data */
|
||||
const data = await f.arrayBuffer();
|
||||
/* data is an ArrayBuffer */
|
||||
const wb = XLSX.read(data);
|
||||
/* do something with the workbook here */
|
||||
console.log(XLSX.utils.sheet_to_json(wb.Sheets[wb.SheetNames[0]]))
|
||||
}
|
||||
drop_dom_element.addEventListener("drop", handleDropAsync, false);
|
||||
```
|
||||
|
||||
## File System Access API
|
||||
|
||||
_Reading Files_
|
||||
|
||||
`window.showOpenFilePicker` shows a file picker and resolves to an array of
|
||||
file handles. When `multiple: false` is set, the array has one element.
|
||||
|
||||
The `getFile` method resolves to a `File` object whose data can be read with
|
||||
the `arrayBuffer` method:
|
||||
|
||||
```js
|
||||
/* Show picker and get data */
|
||||
const [hFile] = await window.showOpenFilePicker({
|
||||
types: [{
|
||||
description: 'Spreadsheets',
|
||||
accept: { 'application/vnd.ms-excel': ['.xlsx', '.xls', '.xlsb', /*...*/] }
|
||||
}],
|
||||
excludeAcceptAllOption: true,
|
||||
multiple: false
|
||||
});
|
||||
const ab = await (await hFile.getFile()).arrayBuffer();
|
||||
|
||||
/* parse */
|
||||
const wb = XLSX.read(ab);
|
||||
|
||||
/* do something with the workbook */
|
||||
console.log(XLSX.utils.sheet_to_json(wb.Sheets[wb.SheetNames[0]]));
|
||||
```
|
||||
|
||||
_Writing Files_
|
||||
|
||||
`window.showSaveFilePicker` shows a file picker and resolves to a file handle.
|
||||
The `createWritable` method resolves to a `FileSystemWritableFileStream`, which
|
||||
readily accepts `Uint8Array` data from `XLSX.write`:
|
||||
|
||||
```js
|
||||
/* Show picker and get handle to file */
|
||||
const hFile = await window.showSaveFilePicker({
|
||||
suggestedName: "SheetJS.xlsx",
|
||||
types: [
|
||||
{ description: 'Excel 2007+ (XLSX)', accept: { 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet': ['.xlsx'] } },
|
||||
{ description: 'Excel 97-2004 (XLS)', accept: { 'application/vnd.ms-excel': ['.xls'] } },
|
||||
{ description: 'Excel 2007+ Binary (XLSB)', accept: { 'application/vnd.ms-excel.sheet.binary.macroEnabled.12': ['.xlsb'] } },
|
||||
/* note that each MIME type must be unique! */
|
||||
]
|
||||
});
|
||||
const wstream = await hFile.createWritable();
|
||||
|
||||
/* get extension */
|
||||
const ext = hFile.name.slice(hFile.name.lastIndexOf(".")+1)
|
||||
/* write */
|
||||
wstream.write(XLSX.write(wb, { bookType: ext, type: "buffer" }))
|
||||
/* close stream to commit file */
|
||||
wstream.close();
|
||||
```

</details>
|
||||
|
||||
## File and Directory Entries API
|
||||
|
||||
In the web browser, the File and Directory Entries API does not project to the
|
||||
local file system. `cordova-plugin-file` *does* write to device in mobile apps!
|
||||
|
||||
_Writing Files_
|
||||
|
||||
```js
|
||||
// Request File System Access
|
||||
window.requestFileSystem(window.PERSISTENT, 0, (fs) => {
|
||||
// Request a handle to "SheetJS.xlsx", making a new file if necessary
|
||||
fs.root.getFile("SheetJS.xlsx", {create: true}, entry => {
|
||||
// Request a FileWriter for writing data
|
||||
entry.createWriter(writer => {
|
||||
// The FileWriter API needs an actual Blob
|
||||
const u8 = XLSX.write(wb, { type: "buffer", bookType: "xlsx" });
|
||||
const data = new Blob([u8], { type: "application/vnd.ms-excel" });
|
||||
// `onwriteend` is called on success, `onerror` called on error
|
||||
writer.onwriteend = () => {}; writer.onerror = () => {};
|
||||
// write the data
|
||||
writer.write(data);
|
||||
});
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
## Internet Explorer
|
||||
|
||||
Internet Explorer offered proprietary APIs that were not adopted by Chromium.
|
||||
|
||||
#### Blob API
|
||||
|
||||
_Writing Files_
|
||||
|
||||
IE10 and IE11 support `navigator.msSaveBlob`. `writeFile` will use the method.
|
||||
|
||||
#### VBScript
|
||||
|
||||
_Reading and Writing Files_
|
||||
|
||||
Internet Explorer 6-9 with VBScript support `Scripting.FileSystemObject`. This
|
||||
is not supported in modern browsers.
|
||||
|
||||
This approach is implemented in the library `readFile` and `writeFile` methods.
|
||||
It requires the shim script to be loaded before the main library script:
|
||||
|
||||
```html
|
||||
<!-- load the shim script first -->
|
||||
<script src="shim.min.js"></script>
|
||||
<!-- then load the main script -->
|
||||
<script src="xlsx.full.min.js"></script>
|
||||
```
|
||||
|
||||
## Other Platforms
|
||||
|
||||
### NodeJS
|
||||
|
||||
`fs.readFileSync` and `fs.writeFileSync` allow for reading and writing files.
|
||||
|
||||
When using `require`, these are supported in `readFile` and `writeFile`:
|
||||
|
||||
```js
|
||||
var XLSX = require("xlsx");
|
||||
var wb = XLSX.readFile("sheetjs.numbers");
|
||||
XLSX.writeFile(wb, "sheetjs.xls");
|
||||
```
|
||||
|
||||
[Installation](../getting-started/installation/nodejs) has a special note for
|
||||
use with NodeJS ECMAScript Modules:
|
||||
|
||||
```js
|
||||
import { readFile, writeFile, set_fs } from 'xlsx';
|
||||
import * as fs from 'fs';
|
||||
set_fs(fs);
|
||||
|
||||
var wb = XLSX.readFile("sheetjs.numbers");
|
||||
XLSX.writeFile(wb, "sheetjs.xls");
|
||||
```
|
||||
|
||||
### Deno
|
||||
|
||||
`Deno.readFileSync` and `Deno.writeFileSync` are supported by `readFile` and
|
||||
`writeFile` out of the box:
|
||||
|
||||
```js
|
||||
// @deno-types="https://cdn.sheetjs.com/xlsx-latest/package/types/index.d.ts"
|
||||
import * as XLSX from 'https://cdn.sheetjs.com/xlsx-latest/package/xlsx.mjs';
