The converter reads the first row of your CSV as the column headers and uses those headers as JSON keys. Every following row becomes one JSON object, with each cell mapped to its column key. The result is a JSON array of objects, the same shape most APIs and JavaScript applications expect. Paste your CSV and the JSON output appears instantly.

About the CSV to JSON Converter

CSV is the universal export format for spreadsheets, databases, and analytics tools, but modern APIs and JavaScript applications speak JSON. This CSV to JSON converter bridges that gap: paste a CSV export from Excel, Google Sheets, or any database dump, and get a clean JSON array of objects ready for your code. The parser follows standard CSV quoting rules, so commas and line breaks inside quoted fields are preserved, and custom delimiters (semicolon, tab, pipe) cover regional Excel exports and TSV files. Because the converter is free and runs entirely in your browser, it is a safe choice for customer lists, financial exports, and any data you would rather not upload to a server.
