FAQ

How does the first row work?

First row becomes JSON keys. Each following row becomes an object with those keys.

Can I use tab as a delimiter?

Yes. Paste a tab character in the delimiter field, or use semicolons or pipes.

What about commas inside values?

Wrap the value in double quotes: "New York, NY"

Is my data sent to a server?

No. Everything runs locally in your browser.
