#FAQ
How does the YAML diff work? ▾
The tool compares YAML documents line by line using a longest common subsequence algorithm, showing added lines in green, removed lines in red, and unchanged lines in the default color.
Is the comparison structure-aware? ▾
The diff is line-based, which works well for YAML since its indentation-based format aligns structure with lines. For structure-aware comparison, try the JSON Diff tool with YAML converted to JSON first.
