How to compare JSON files online?

Paste your original JSON in the "Original Text" field and the modified JSON in the "Modified Text" field. Select "JSON" from the language dropdown for proper syntax highlighting, then click "Compare". The tool will highlight all differences, including added, removed, and modified properties. Since JSON comparison happens locally, your sensitive data never leaves your browser.

Can I use this tool for Git merge conflicts?

Yes! This tool is perfect for resolving Git merge conflicts. Simply copy the original version (usually marked with ` >>>>>>`) into the "Modified Text" field. The side-by-side diff view makes it easy to see exactly what changed and merge the changes manually.

What is the difference between Split View and Inline View?

Split View (side-by-side) displays the original and modified text in two columns, making it easy to compare corresponding lines. Inline View shows changes within a single column with inline indicators (+, -, ~) for additions, deletions, and modifications. Split View is generally better for large files, while Inline View is more compact.

How does the MiniMap feature help with large files?

The MiniMap is a small overview of your entire file displayed on the right side of the editor. Unlike other online diff tools that require scrolling through thousands of lines, you can click anywhere on the MiniMap to instantly jump to that section of the file. This feature, borrowed from VS Code, makes navigating large configuration files or codebases much more efficient.

Is it safe to compare sensitive code or configuration files?

Absolutely! All comparison happens 100% in your browser using client-side JavaScript. Your code, configuration files, or any text you paste is never sent to any server, stored, or logged. This makes our tool perfect for comparing sensitive data like API keys, database configurations, or proprietary code.

Can I compare XML or SQL files?

Yes! Select "XML" or "SQL" from the language dropdown to enable proper syntax highlighting for these formats. The diff algorithm works with any text format, but syntax highlighting makes it easier to understand the structure of XML documents or SQL queries when comparing them.

About Text & Code Comparison

A diff checker (difference checker) is an essential tool for developers to compare two versions of text or code files. Unlike traditional diff tools that upload your data to servers, our tool processes everything locally in your browser, ensuring complete privacy and security. Whether you're resolving Git merge conflicts, comparing configuration files, or reviewing code changes, our VS Code-like interface provides an intuitive and powerful comparison experience. The built-in MiniMap feature makes it easy to navigate through large files, a capability that many online diff tools lack.
