Frequently Asked Questions
How does the compare and diff tool work?
Paste two text objects (JSON, code, or any text) into the left and right editors. The tool will compare them line-by-line and highlight added, removed, and modified lines with git-style diff visualization.
Can I compare non-JSON text?
Yes, this tool works with any text format. If the text is valid JSON, it will be formatted for better comparison. Otherwise, it compares the text as-is.
How are differences displayed?
Differences are shown inline with color-coded highlighting: green for added lines, red for removed lines, and yellow for modified lines, similar to git diff.
