About CSV ↔ JSON
Convert CSV data to JSON or JSON to CSV in the browser, with live conversion and a downloadable result.
Move between tabular and structured data
CSV is convenient for spreadsheets and tables, while JSON is common in APIs and application configuration. The converter lets you switch between CSV → JSON and JSON → CSV and see the result immediately.
You can paste the data directly into the editor, review the generated output and download the result. This is useful when moving a dataset between a spreadsheet-oriented workflow and a developer-oriented workflow.
Local data handling
Conversion is performed in the browser. The intended workflow does not send the pasted dataset to a My Karya Kit processing server. This is helpful for business exports and other data that should stay under your control.
Even with local processing, treat the input as sensitive if it contains personal or confidential information. Your clipboard, operating system and destination application remain outside this site's control.
Check the output
CSV and JSON have different data models, so a conversion is a transformation rather than a perfect preservation of every spreadsheet convention. Review headers, values, quoting and the resulting structure before importing the output into another system.
