CSV to JSON

Convert CSV data to JSON for APIs and applications.

Paste a CSV file and get an array of objects keyed by the header row, ready to drop into an API request, a seed file, or a unit-test fixture. The parser handles quoted cells, escaped quotes, and the usual delimiters without configuration.

Common use cases: importing a spreadsheet into your application, converting a CSV export from a third-party tool into a format your API understands, generating fixtures for tests, and quickly browsing a CSV in a hierarchical viewer.

Frequently asked questions

Does it handle quoted cells with commas inside?
Yes. The parser follows RFC 4180: cells wrapped in double quotes can contain commas, newlines and escaped quotes ("") without breaking the row.
What if my CSV uses semicolons or tabs?
Many European locales export with ; as the separator, and TSV files use \t. The tool auto-detects the most likely delimiter from the first few lines.
How are numbers and booleans typed?
By default everything is a string, safest for round-tripping IDs that look numeric (postal codes, phone numbers, leading-zero codes) without silently losing the zeros. Use the type-coercion toggle if you want "42" to become 42 and "true" to become true.
My first row is data, not headers, what now?
Toggle the "first row is header" option off. The output will be an array of arrays instead of an array of objects, preserving column order.
