Common problems and fixes

All values in the JSON are strings, but I need numbers and booleans.

CSV stores everything as text. The converter produces string values for all fields. Parse numbers and booleans in your application code after conversion.

The CSV has no header row and the JSON keys are wrong.

This converter uses the first row as column headers. If your CSV has no header row, add one before converting.

Values containing commas are splitting into extra columns.

Make sure comma-containing values are wrapped in double quotes in the CSV. Most spreadsheet exports handle this automatically.

Frequently asked questions

How do I convert CSV to JSON?

Paste your CSV into the input box, run the converter, and copy or download the JSON output.

Does this CSV to JSON converter use the first row as headers?

Yes. The first CSV row is used as the header row and each following row becomes an object in the JSON array.

Will numeric values be numbers or strings in the JSON output?

Strings. CSV doesn't encode types, so the converter treats all values as text. Convert to numbers in your application code if needed.

What if my CSV has quoted values containing commas?

Standard CSV quoting is handled correctly. A value like "Smith, John" stays as one field rather than splitting on the comma.

Can I paste CSV exported from Excel or Google Sheets?

Yes. Both produce standard comma-delimited CSV that converts cleanly.

Is this CSV to JSON converter free?

Yes. It is free to use in your browser.
