Tools that turn one representation of the same data into another: YAML and JSON, CSV and JSON, Markdown and HTML, Unix timestamps and dates, and identifiers between naming conventions. The YAML, CSV and timestamp converters work in both directions, and the parsers report errors by line and column instead of guessing. Conversion happens in your browser, so config files, exports and logs never leave your machine.
