About the JSON / CSV Converter
Turn a JSON array of objects into a clean CSV spreadsheet, or turn CSV rows back into structured JSON. The converter reads every field name across your records to build a complete set of columns, and it correctly quotes values that contain commas, quotes or line breaks.
When converting CSV to JSON, numbers and true/false values are detected automatically so your output is properly typed. Choose a comma, semicolon or tab delimiter to match your source file.
Is my data private? Yes. All conversion happens in your browser, so sensitive data is never uploaded.
