Frequently Asked Questions
How does the text diff work?
The text diff tool splits both inputs into individual lines and uses the Longest Common Subsequence (LCS) algorithm to identify the minimum set of changes needed to transform one text into the other. Lines present only in the original are shown in red (removed). Lines present only in the modified version are shown in green (added). Matching lines are shown as unchanged.
What can I use a text diff tool for?
Text diff tools are useful for comparing code versions, reviewing document edits, checking configuration file changes, comparing API responses across environments, and identifying what changed between two versions of any text. Developers commonly use diff tools to review changes before committing code.
