About this tool

Convert CSV rows into JSON objects using the first row as headers. Processing happens locally in your browser, so your input is not sent to a server or included in analytics.

Frequently asked questions

Does it support quoted commas and newlines?

Yes. Quoted CSV fields may contain commas, escaped quotes, and line breaks.

Are values inferred as numbers?

No. CSV cell values are preserved as strings.

What if a row has a different number of columns?

The converter reports an error instead of silently dropping or inventing values.
