YAML viewer and editor
Inspect and edit YAML in your browser
Work with YAML source, a structured preview, formatting tools, and diffs without installing a separate editor or routinely uploading configuration data.
Open File ViewerChoose or paste YAML after the viewer opens.
What the YAML viewer supports
- Syntax-aware source editing for YAML and YML files.
- Structured previews for mappings, sequences, and scalar values.
- Formatting plus original-versus-current comparisons.
- Table and form tools when the document shape supports them.
Privacy and limitations
The default workflow parses the document locally. YAML features vary between parsers, so application-specific tags or malformed documents may require their original toolchain.
