Text & JSON Diff Checker
Compare captured responses, configurations or token claims in your browser, with line differences, structural JSON paths and list set operations.
About Text & JSON diffFeatures & how to use
Compare text lines, JSON fields and lists locally. Inspect additions and removals, compare indicator sets and export differences without uploading data.
What it can do
- Compare ordered text lines with original and modified line numbers.
- Compare JSON structurally, ignoring object key order while preserving array order and value types.
- Calculate list intersection, union and one-sided differences; optionally trim line edges.
- Bounded worker execution, input limits and cancellation protect against oversized comparisons.
How to use it
- Paste original and modified input, or load the example JSON documents.
- Choose Line diff, Structural JSON or a list operation, then select Compare.
- Review changes and copy or download the complete result. JSON comparison uses standard JavaScript number precision.
