CSV Input
Output

CONVERT

First row is used as object keys. Quoted fields with commas are handled correctly.

Runs entirely in your browser

How it works

The CSV is parsed field-by-field in JavaScript, handling quoted fields, embedded commas, and escaped quotes. The first row becomes the object keys. All parsing runs locally in your browser.

Processing runs in your browser

All conversion happens inside your browser tab using JavaScript. Our servers are not involved at any point.

After converting, pretty-print or minify the output with the JSON formatter. For escaping commas or quotes inside cells, try URL encode. To convert formatted SQL dumps into rows, see the SQL formatter.

Frequently asked questions

What JSON structure is produced?
An array of objects, one per CSV data row. Keys come from the header row, values come from each subsequent row.
Does it handle quoted fields with commas inside?
Yes. Fields wrapped in double quotes are parsed correctly, including commas, newlines, and escaped quotes inside the value.
Is my CSV data uploaded anywhere?
All parsing runs in JavaScript inside your browser tab. Our servers are not involved at any point.
What if my CSV has no header row?
The first row is always treated as keys. If your CSV lacks a header, add one manually before pasting so the JSON keys are meaningful.
