JSON ↔ CSV Converter
Convert data between JSON (array of objects) and CSV bidirectionally. Paste and convert instantly in the browser, no file upload needed.
How to use?
If you're in JSON → CSV mode, paste a JSON array of objects. Going the other way, in CSV → JSON mode, paste a CSV whose first line is the header. Everything gets converted on the spot, right inside the browser.
Convert between JSON and CSV both ways
JSON is the language of APIs and CSV is the language of spreadsheets. Crossing those two worlds becomes routine, whether you're exporting data from a system into Excel or turning a table into a format code can read. This converter handles the translation in both directions in the same moment.
Paste a JSON array of objects and the matching CSV comes back, with headers taken from the keys. Paste a CSV and the structured JSON shows up. Good for prepping data before an import, opening an API response in a spreadsheet, or converting a report without firing up any heavy program.
None of it goes through a server. Everything happens in the browser, with no file uploads, and your data never leaves the device, which keeps it safe to convert even sensitive information.
