How to use YAML Validator & Error Finder
Validate YAML syntax online, locate errors by line and column, and inspect the parsed structure before downloading JSON.
- Enter the required values or paste text into the interactive workspace.
- Adjust available precision, format, unit or bulk settings as needed.
- Run the calculator or generator and review all output information.
- Download the resulting file or CSV summary; batch outputs can be downloaded as ZIP where available.
How the tool works
YAML syntax is parsed by a dedicated YAML library in the browser, including indentation, arrays, anchors, mappings and scalar values within supported YAML syntax.
Example: Paste a configuration containing `server:\n port: 3000`. If indentation is malformed, the checker reports the parser’s line and column.
Technical limits: tool-specific validation protects browser memory, input parsing and export reliability. Certain file types or uncommon data may be rejected. Always check important financial results or fabrication files using their original records and professional software.
Frequently asked questions
Does this validate Kubernetes or Docker Compose schemas?
No. It checks YAML syntax, not application-specific schemas or Kubernetes semantics.
Will it show exact syntax errors?
It reports the line and column supplied by the YAML parser. Some semantic configuration problems are not detectable from YAML syntax alone.
Is private YAML uploaded?
The source is processed in your browser. The parser library loads from a CDN.
Can I validate multiple YAML files?
Yes. Upload up to 12 small YAML/YML/TXT files per batch.
Privacy and compatibility
Input is handled locally in the browser by Solvory scripts and selected third-party parsing or export libraries. The libraries may download from a CDN. Uploaded file contents are not intentionally sent to a Solvory processing server. Browser features and file encodings may influence compatibility, and generated files must be saved before closing the tab.
