Text Diff (JSON/YAML/XML)

Usage

• Enter documents to compare in Input 1 and Input 2, or upload files.
• Format is automatically detected, but you can manually select using radio buttons.
• Click the "Diff" button to compare the two documents.
• View added/deleted/modified parts in colors in the Diff area.
• Comparison results are displayed in the top Alert, showing whether they are identical and the number of differences.
• JSON/YAML/XML formats are normalized before comparison, so order or format differences are ignored.

Input, output, limits

Input is two documents (paste or file). Output is a Monaco Diff view plus a difference count. JSON/YAML/XML are normalized first. Nothing is uploaded.

Example

Input 1: {"a":1} / Input 2: {"a":2} → Diff highlights the changed value. JSON that only differs in key order is treated as identical.

JSON

• Key Order: Object key order is ignored when comparing.
• Whitespace: Whitespace and indentation differences are ignored.
• Array Elements: Intelligently detects addition, deletion, and movement of array elements.
• Data Type Change: Detects both value and data type changes.

YAML

• Key Order: Object/map key order is ignored when comparing.
• Comments: Comment (#) changes are ignored.
• Style Variation: Style differences (block/flow) are ignored, only final structure is compared.
• Multiple Documents: Multiple documents (separated by ---) are compared individually.

XML

• Attribute Order: XML node attribute order is ignored.
• Whitespace Nodes: Indentation or line break text nodes are ignored.
• Namespace: Namespace declaration changes are shown as important differences.
• Comments: Comment changes are ignored.
