## Features

Straightforward excel file parser and builder.

- Relies on [SheetJS xlsx](https://github.com/SheetJS/sheetjs) module to parse/build excel sheets.
- Built with [TypeScript](https://www.typescriptlang.org/) for static type checking with exported types along the
  library.

## Install

```bash
npm install node-xlsx --save
```

## Quickstart

### Parse an xlsx file

```js
import xlsx from 'node-xlsx';
// Or var xlsx = require('node-xlsx').default;

// Parse a buffer
const workSheetsFromBuffer = xlsx.parse(fs.readFileSync(`${__dirname}/myFile.xlsx`));
// Parse a file
const workSheetsFromFile = xlsx.parse(`${__dirname}/myFile.xlsx`);
```

### Build an xlsx file

```js
import xlsx from 'node-xlsx';
// Or var xlsx = require('node-xlsx').default;

const data = [
  [1, 2, 3],
  [true, false, null, 'sheetjs'],
  ['foo', 'bar', new Date('2014-02-19T14:30Z'), '0.3'],
  ['baz', null, 'qux'],
];
var buffer = xlsx.build([{name: 'mySheetName', data: data}]); // Returns a buffer
```

### Custom column width

```js
import xlsx from 'node-xlsx';
// Or var xlsx = require('node-xlsx').default;

const data = [
  [1, 2, 3],
  [true, false, null, 'sheetjs'],
  ['foo', 'bar', new Date('2014-02-19T14:30Z'), '0.3'],
  ['baz', null, 'qux'],
];
const sheetOptions = {'!cols': [{wch: 6}, {wch: 7}, {wch: 10}, {wch: 20}]};

var buffer = xlsx.build([{name: 'mySheetName', data: data}], {sheetOptions}); // Returns a buffer
```

### Spanning multiple rows `A1:A4` in every sheets

```js
import xlsx from 'node-xlsx';
// Or var xlsx = require('node-xlsx').default;

const data = [
  [1, 2, 3],
  [true, false, null, 'sheetjs'],
  ['foo', 'bar', new Date('2014-02-19T14:30Z'), '0.3'],
  ['baz', null, 'qux'],
];
const range = {s: {c: 0, r: 0}, e: {c: 0, r: 3}}; // A1:A4
const sheetOptions = {'!merges': [range]};

var buffer = xlsx.build([{name: 'mySheetName', data: data}], {sheetOptions}); // Returns a buffer
```

### Spanning multiple rows `A1:A4` in second sheet

```js
import xlsx from 'node-xlsx';
// Or var xlsx = require('node-xlsx').default;

const dataSheet1 = [
  [1, 2, 3],
  [true, false, null, 'sheetjs'],
  ['foo', 'bar', new Date('2014-02-19T14:30Z'), '0.3'],
  ['baz', null, 'qux'],
];
const dataSheet2 = [
  [4, 5, 6],
  [7, 8, 9, 10],
  [11, 12, 13, 14],
  ['baz', null, 'qux'],
];
const range = {s: {c: 0, r: 0}, e: {c: 0, r: 3}}; // A1:A4
const sheetOptions = {'!merges': [range]};

var buffer = xlsx.build([
  {name: 'myFirstSheet', data: dataSheet1},
  {name: 'mySecondSheet', data: dataSheet2, options: sheetOptions},
]); // Returns a buffer
```

_Beware that if you try to merge several times the same cell, your xlsx file will be seen as corrupted._

- Using Primitive Object Notation Data values can also be specified in a non-abstracted representation.

Examples:

```js
const rowAverage = [[{t: 'n', z: 10, f: '=AVERAGE(2:2)'}], [1, 2, 3]];
var buffer = xlsx.build([{name: 'Average Formula', data: rowAverage}]);
```

Refer to [xlsx](https://sheetjs.gitbooks.io) documentation for valid structure and values:

- [cell object]: (https://sheetjs.gitbooks.io/docs/#cell-object)
- [data types]: (https://sheetjs.gitbooks.io/docs/#data-types)
- [Format](https://sheetjs.gitbooks.io/docs/#number-formats)

### Troubleshooting

This library requires at least node.js v10. For legacy versions, you can use this workaround before using the lib.

```sh
npm i --save object-assign
```

```js
Object.prototype.assign = require('object-assign');
```

### Contributing

Please submit all pull requests the against master branch. If your unit test contains javascript patches or features,
you should include relevant unit tests. Thanks!
