CSV to JSON

How to convert CSV to JSON

1. Paste your CSV, or choose a file. You can also copy cells straight from Excel or Google Sheets, which pastes as tab-separated text.
2. The separator is detected for you. With "First row is headers" on, each row becomes an object with those names as keys.
3. Copy the JSON or download it. Switch Convert to JSON to CSV to go the other way.

Frequently asked questions

Are quoted fields handled?

Yes. Fields in double quotes can contain commas, line breaks and doubled quotes, as in files saved by Excel.

Why are some values numbers and others text?

With "Convert numbers" on, values that are plain numbers become JSON numbers. Values such as 007 or 1,5 stay text so nothing is lost; turn the option off to keep everything as text.

Is my data uploaded?

No. The file is read and converted in your browser.
