YAML Diff Tool
Compare two YAML documents key by key
Runs 100% in your browser — nothing is ever uploaded.
What is YAML Diff?
Paste two YAML documents (separated by a ----- line) and get a semantic comparison: keys are flattened to dot paths and every changed, added or removed value is listed clearly. Unlike a text diff, formatting, ordering and comments do not create noise — ideal for Kubernetes manifests and CI configs.
How to use YAML Diff
- Paste your 2× YAML into the input box or click “Load sample” to try it.
- Adjust the options in the toolbar if needed (root name, format, delimiter …).
- Click the convert button — the diff output appears instantly in the output pane.
- Copy the result with one click or download it as a file.
ConvertLab FAQ
Is the YAML diff tool free?
Yes — 100% free, no signup, no limits, no watermarks. Use it as often as you like.
Why is a semantic diff better than a text diff for YAML?
Because YAML allows different indentation, key order and quoting for identical data. The semantic diff parses both documents and compares actual values by path, so only real configuration changes are reported.
Is my data uploaded to a server?
No. Everything runs entirely in your browser with JavaScript — your data never leaves your device, which makes the tool safe even for confidential files.
Are these converters free?
Yes — every ConvertLab tool is 100% free with no signup, no limits and no ad walls.
Is my data uploaded anywhere?
No. All conversions (JSON, CSV, XML, YAML, INI, .env) run entirely in your browser. Nothing ever leaves your device.
Do these tools work offline?
Yes — once the page is loaded, every converter works without an internet connection.
