Data format conversion is essential when exchanging data between different systems and tools. REST APIs speak JSON, configuration files often use YAML or TOML, legacy integrations require XML, and spreadsheets work with CSV. These converters eliminate manual reformatting by handling the transformation instantly in your browser.

The collection supports bidirectional conversion between JSON, YAML, XML, CSV, and TOML, plus specialized conversions from JSON to TypeScript type definitions and from Markdown to HTML. All conversions run client-side — no data leaves your browser.
