Data Format Converters

Switch data between JSON, CSV, XML, YAML, Excel, TOML and other formats without a backend, an upload or a spreadsheet app. The converters cover the pairs developers and analysts actually need: JSON to CSV, XML, YAML, Excel, HTML and Markdown tables, and SQL INSERT statements — and the same set in reverse, so CSV, XML, YAML and Excel can all become JSON again. There are also smaller format bridges: TOML to JSON and YAML, .env files to JSON and back, query strings to JSON and back, CSV to vCard and back, SQL results to JSON, and geographic formats — GeoJSON, KML and GPX — converted between each other and to CSV. Paste your data or drop in a file, pick the target format, and download the result. Everything is processed in your browser, which matters when the data is a real export with customer details, API keys or internal values you do not want on a server. The tools are handy for reshaping an API response for a spreadsheet, turning a config file into a table, or preparing data for import into another tool. Free, with no account, and each converter shows its result immediately.
