How to use Excel to CSV / JSON

- Set the options you need, then press the button to start.
- Download the result. The whole job happens in your browser; nothing is uploaded.
Good to know
Every sheet becomes its own CSV file, saved as UTF-8 so accented and non-Latin characters survive. Choose JSON instead if the data is headed for a program. This tool is light and starts instantly.
Questions and answers
Is Excel to CSV / JSON really free?
Yes. There is no charge, no account and no limit on how many files you convert.
Are my files uploaded anywhere?
No. The conversion runs inside your browser, on your own device. Your files are never sent to us or to anyone else.
Is there a file-size limit?
There is no fixed limit. Very large files depend on how much memory your device has; a computer copes with more than a phone.
Does it work without an internet connection?
Yes, once you have opened the tool while online. You can also save the whole site for offline use from the home page.
