Compare two JSON documents for added, removed, and changed values. Text Diff and Structured Diff, for integration debugging. Data stays local.
Paste one object on each side (A / B). Text Diff shows whitespace and key order. Structured Diff focuses on paths and values.
In integration work the usual hits are "a new field appeared," "the status changed," or "the array is one item short." Read the path, then decide whether frontend or backend should change.
Both documents are compared locally. Nothing is sent to a third-party Diff service.
When keys were reordered or whitespace drifted, but you only care about business values, use Structured Diff and skip the layout noise.
Comparison follows the current order. A reorder may look like a delete plus an add. If you have a stable id, sort by id first.
Text Diff says yes. Structured Diff focuses on paths and values, so it ignores layout noise.
In current order. If items only swapped places, you may see a delete plus an add. Read that in context.
Convert to JSON on the YAML page first, then come back here.
No.
Format both sides first, or use Structured Diff.
This page has no ignore rules. Delete tokens and timestamps by hand, then compare.
Diff first so you see the gap, then decide which side wins.
Adds, deletes, and changes are marked by path. Read the path first, then the old and new values.
