Put it to work
Paste configuration versions to inspect added and removed lines.
From input to output
- Open Text diff and load the example.
- Read the format notes, choose your options, and replace the example with your input. Start with test data instead of sensitive information.
- Run the tool and inspect the result and status. If an error appears, correct the input format and run it again.
- Copy the output or download a file. Generated and converted results are not saved automatically.
When ignoring whitespace changes the meaning
Ignoring whitespace helps compare prose, but may hide meaningful changes in Python indentation, YAML structure, or string literals. Review code with whitespace preserved first. Line mode marks whole lines as added or removed; word mode shows smaller word and punctuation changes. The output’s + and - markers identify additions and deletions without relying on color.
Example input
Before: const theme = "light"; After: const theme = "dark";
Reading the result
-const theme = "light"; +const theme = "dark";
Details that matter
Format and meaning
Line mode suits configuration files; word mode suits prose edits.
Using it correctly
Ignoring whitespace normalizes repeated and trailing whitespace before comparing.
Supported scope and limits

Split inputs that exceed the limit. If a format or algorithm is unsupported, choose a tool that matches your requirements instead of silently changing the format.
