About CSV ↔ JSON Converter

CSV and JSON are the two most common data formats you'll run into when working with spreadsheets, APIs, and databases. This tool converts between them instantly — paste a CSV and get clean structured JSON, or paste JSON and get a formatted CSV ready to open in Excel or Google Sheets. A table preview lets you visually verify the data looks right before downloading.

File uploads are supported too, so you can drag in a .csv or .json file directly. Perfect for data migration, API response inspection, import/export workflows, and any situation where you need to move data between tools that use different formats. Clean, fast, and no server involved.
