🧾 CSV CONVERTER • 100% PRIVATE
CSV Converter — CSV to JSON and Back
Spreadsheet-shaped data in, API-shaped data out — with proper quoting, computed locally.
CSV is the universal interchange format for spreadsheets, and JSON is the universal format for APIs. This converter handles both directions with the edge cases done right: fields wrapped in double quotes, commas inside fields, escaped quotes, and headers mapped to keys. Because the parse runs in your browser, a database export or a customer list never touches a server.

How to use these converters
- Paste your CSV (headers in the first row).
- Click Convert — quoted fields with commas inside are parsed correctly.
- Copy or download the JSON array of objects.
FAQ
- Does it handle commas inside quoted fields? Yes — standard CSV quoting (double quotes around fields, doubled quotes inside) is parsed and generated correctly in both directions.
- Is my CSV uploaded anywhere? No — the conversion is pure string processing in your browser.
