About this tool

Paste CSV text or upload a .csv file, and the equivalent JSON array of objects appears on the right, using your first row as the object keys.

Frequently asked questions

How are columns mapped to JSON keys?
The first row of your CSV is treated as the header row, and its values become the object keys for every following row.
Does this handle quoted fields with commas or newlines inside them?
Yes — quoted fields ("like, this") are parsed correctly, including embedded commas, newlines, and escaped "" quotes.
Is my CSV sent to your servers?
No. The conversion runs entirely in your browser, whether pasted or uploaded as a file.
