CSV to JSON Converter
Paste CSV data to get a clean JSON array of objects, with proper handling of quoted fields and commas — all in your browser.
Turn spreadsheets into API-ready JSON
CSV is how data leaves spreadsheets and databases; JSON is what code and APIs actually consume. This converter bridges the two. Paste any CSV and it reads the header row as keys and each subsequent row as an object, giving you a clean array of objects you can drop straight into a request body, a config file, or a mock dataset.
It parses CSV properly rather than just splitting on commas, so fields wrapped in quotes can contain commas, escaped quotes, and even line breaks without corrupting the output. If your file has no header row, switch to array mode and each line becomes a simple array of values instead. The result is pretty-printed and ready to copy.
Private and instant
Everything runs in your browser, so even sensitive exports never leave your device.
Frequently Asked Questions
How does the CSV to JSON converter work?
It reads the first row as headers and turns each following row into a JSON object keyed by those headers, producing an array of objects — the format most APIs and apps expect.
Does it handle quoted fields and commas inside values?
Yes. It follows standard CSV rules, so values wrapped in double quotes can contain commas, quotes (escaped as ""), and line breaks without breaking the parse.
Can I get an array of arrays instead of objects?
Toggle the “no header row” option and each row becomes an array of values, useful when your CSV has no header line.
Is my data private?
Yes. Conversion happens entirely in your browser — nothing is uploaded or stored.
