Frequently asked questions

Are my files uploaded to a server?

No. Everything is processed inside your browser, and your files never leave your device.

What file size is supported?

There's no fixed limit. Sheets with hundreds of thousands of rows can be slow or use a lot of memory; use a computer for those.

Are formulas and formatting preserved?

The values are converted. Formulas are saved with their result, and visual formatting is lost.

About this tool

Turn a list of JSON objects into a table you can open in Excel or Google Sheets. The CSV file uses UTF-8 encoding with BOM so accented characters display correctly in Excel.

Because everything happens on your device, you can convert customer lists, payrolls or inventories without exposing them on the internet.

If accented characters look wrong, save your original file with UTF-8 encoding.
