CSV to JSON Converter
Paste CSV and get a clean JSON array of objects instantly. Headers become keys; numbers and booleans are detected automatically.
Frequently Asked Questions
How are CSV columns mapped to JSON?
The first row is treated as headers and becomes the key names. Every row after that becomes one JSON object, with each column value assigned to its matching header key.
Does it detect numbers and booleans automatically?
Yes. Values like 30 or true are converted to a JSON number or boolean rather than staying as text — this matches how most APIs expect typed JSON data.
Can it handle commas inside a quoted field?
Yes. A field wrapped in double quotes — like "Smith, John" — is parsed as a single value even though it contains a comma, following standard CSV quoting rules.
What if my CSV has an empty cell?
An empty cell becomes an empty string ("") in the resulting JSON, keeping every object shape consistent even when some rows have missing data.
Can I open a spreadsheet exported from Excel?
Yes. Export or copy your Excel/Google Sheets data as CSV, then paste it in — standard comma-separated CSV with a header row works out of the box.
