save-csv

Download an array of objects as a CSV file in the browser

save-csv is a tiny library (892 bytes gzipped) that creates an CSV file from a array of objects with matching keys and triggers a download in the browser. Features:

• Automatically detects the value separator (usually ,) based on the user's regional settings.
• Saves UTF8 by default and helps Excel to recognize this by adding a byte order mark.
• Fully configurable. Every output character can be modified via options.

Example

<script src="save-csv.min.js"></script>

saveCsv([
  {a:1, b:2},
  {a:3, b:4},
]);

Output

a,b
1,2
3,4
