Move Data Between Formats Without Breaking It

Every system seems to want data in a different format: a spreadsheet export is CSV, an API wants JSON, a config file is YAML or TOML, and an older integration speaks XML. These converters handle the details - quoted fields, nesting, escaping - and run in your browser, so customer lists and exports stay on your device.

Spreadsheets and APIs

The most common jobs are CSV to JSON and JSON to CSV. Tab-separated files convert with TSV to CSV and CSV to TSV, and XML-based systems are covered by CSV to XML and XML to CSV.

Configuration Formats

JSON to YAML and YAML to JSON for Docker, Kubernetes and CI files.
JSON to XML and XML to JSON.
INI to JSON and TOML to JSON, and back again.

Documents

Turn notes into web pages with Markdown to HTML, go the other way with HTML to Markdown, or strip markup with HTML to Text. Our CSV to JSON guide covers the common pitfalls.
