Guide to Visual Studio Git Changes & Code Comparison
Side-by-Side vs. Inline Diff View
Side-by-Side (Split) View: Displays the original and modified files simultaneously in two vertically-aligned panes. This is ideal for desktop screens when comparing large structural changes, refactored methods, or layout differences.
Inline (Unified) View: Stacks deletions directly above additions within a single continuous editor pane, identical to GitHub commit views and standard Git terminal patches.
Keyboard Shortcuts & Pro Tips
- F7 / Shift + F7: Instantly jump forward or backward between changed diff hunks.
- Ctrl + F: Search text inside whichever editor pane currently has focus.
- Collapse Unchanged Blocks: Fold uninterrupted identical code so you can focus exclusively on modifications.
- Word-Level Micro Diff: Notice subtle character/variable name updates with bright contrasting highlighting within the modified line.
Frequently Asked Questions
How do I compare two text or code files online?
Paste your original code or base version into the left editor and the modified version into the right editor. The diff viewer instantly calculates line and character-level differences in real time, highlighting additions in green and deletions in red.
Is my code private and secure when using this online diff tool?
Yes, 100% private. All diff computations and syntax coloring run entirely in your local browser using client-side WebAssembly and JavaScript. No text, source code, or proprietary data is ever uploaded or transmitted to any server.
What is the difference between Side-by-Side and Inline diff view?
Side-by-Side (Split) view displays original and modified versions in two parallel side-by-side panes, making it ideal for desktop screens. Inline (Unified) view stacks deletions directly above additions in a single vertical stream, which matches git diff terminal output and is ideal for mobile and smaller screens.
Can I export or download a Git patch (.patch) file?
Yes. Click the 'Download .patch' button on the toolbar to export a standard unified Git diff patch file that can be applied to repositories using the git apply command.
How do I ignore whitespace and formatting differences?
Simply check the 'Ignore Whitespace Differences' box in the options toolbar. The tool will ignore tabs, spaces, and line-ending variations (CRLF vs LF), focusing only on actual functional code changes.
