## 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');
|
||||
```
|
||||

||||
