About Converter Tools
Converters translate data from one format to another. Developers constantly move data between JSON, CSV, XML and YAML, and these tools make the conversion a single paste-and-click operation instead of a scripting task.
Each converter validates your input and shows clear errors when something is malformed, so you can fix the problem quickly. Conversions happen client-side, meaning even large datasets are handled locally without uploading sensitive records to a third party.
Use converters together: turn a JSON API response into a CSV for a spreadsheet, or import a CSV export and reshape it into JSON for your application. The related links on each page connect the full conversion chain.
