Frequently Asked Questions

FAQs about CSV to JSON

How are headers detected?

The first row of your CSV is automatically used as the key names for each JSON object.

Does it handle quoted values?

Yes. Values wrapped in double quotes are unquoted. This handles values containing commas.

Can I upload a CSV file?

Yes. Click the Upload button to select a .csv file from your computer.

What if rows have different numbers of columns?

Missing values are set to empty strings. Extra values beyond the header count are ignored.

Is my data safe?

Yes. All conversion happens in your browser. No data is sent to any server.
