About This Tool
Diff Checker compares original and modified text line by line and marks changed line positions. Lines at the same index are compared with exact string equality; this is not a character-level or moved-block diff.
What You Can Do
Side-by-side view
Diff Checker accepts Two plain-text blocks as its documented input.
Changed-line count
The current Diff Checker implementation produces Visual line comparison.
Safe text-node rendering
Lines at the same index are compared with exact string equality; this is not a character-level or moved-block diff.
How to Use

Practical Use Cases
Diff Checker workflow
Use Diff Checker when you need to compares original and modified text line by line and marks changed line positions.
Result preparation
Create a reviewable Visual line comparison result while retaining the original Two plain-text blocks.
Privacy and File Processing
Diff Checker keeps its Two plain-text blocks input in browser memory while the operation runs. The workflow creates Visual line comparison for local preview or download and does not send the entered values or selected file bytes to the GXA Toolbox application server.
Supported Inputs and Outputs
Input
- Two plain-text blocks
Output
- Visual line comparison
How It Works
Lines at the same index are compared with exact string equality; this is not a character-level or moved-block diff.
Quality and Fidelity
Lines at the same index are compared with exact string equality; this is not a character-level or moved-block diff.
Limitations and Important Notes
- Inserted lines can make later unchanged lines appear changed.
- Whitespace and letter case are significant.
Worked Example
Compare two configuration excerpts to locate which numbered lines differ.
Helpful Tips
- Keep a copy of the original Two plain-text blocks while using Diff Checker.
- Validate the Visual line comparison in its intended destination context.
Frequently Asked Questions
Does Diff Checker execute on the application server?
No. The current Diff Checker operation runs in the browser.
Is the Diff Checker transformation always reversible?
Not necessarily. Inserted lines can make later unchanged lines appear changed.
What should I verify after using Diff Checker?
Lines at the same index are compared with exact string equality; this is not a character-level or moved-block diff.
