SheetClip.js

Copy/paste from your HTML5 web app to a spreadsheet

Tiny library that transforms JavaScript 2-dimensional arrays to clipboard strings compatible with spreadsheets such as Microsoft Excel, Google Docs, LibreOffice and OpenOffice

Usage

Convert array to string (to copy it to Excel)

var str = SheetClip.stringify(arr);

The above line will convert a 2-dimensional array:

var arr = [
  ['A', 'B', 'C'],
  ['D', 'Some\nlong\ntext', 'F'],
  ['G', 'H', 'I']
];

To a string:

A/tB/tC/nD/t"Some/nlong/ntext"/tF/nG/tH/tI/n

Which, pasted from clipboard to an Excel sheet will render as:

A B C
D Some
long
text
F
G H I

Convert string to array (to paste it from Excel)

var arr = SheetClip.parse(str);

The above line parses a string:

A/tB/tC/nD/t"Some/nlong/ntext"/tF/nG/tH/tI/n

that was copied to clipboard from Excel sheet:

A B C
D Some
long
text
F
G H I

to a 2-dimensional array:

[
  ['A', 'B', 'C'],
  ['D', 'Some\nlong\ntext', 'F'],
  ['G', 'H', 'I']
]

Notes

This library was created with the intention to be used in Handsontable. I decided to make it a separate project in case somebody else needs it.

It does not provide you with clipboard access in JavaScript. That part still needs to be figured out by you. There are various ways to achieve it but none of them is perfect. Probably the most compatible with all the browsers is to keep a hidden <textarea> on the page that is always focused. Then, you can fill it with value that can will be automatically copied to clipboard when the user presses CTRL+C. Analogously, pressing CTRL+V will fill the focused textarea with the value from clipboard.

At least this is the way how Handsontable does it.
