About CSV to JSON Converter
Turning a CSV export into JSON is a frequent step when moving data into APIs and apps. This tool treats the first line as column headers and converts each subsequent row into an object, producing a clean JSON array. It handles simple comma-separated data and runs entirely in your browser, so even sensitive exports stay private.
FAQ
Does the first row need to be headers?
Yes — the first line is used as the object keys for every row that follows.
Does it handle quoted commas?
It splits on commas, so values containing commas should be cleaned or use the dedicated JSON-CSV tool.
Is my data uploaded?
No, the conversion runs locally in your browser.
