Compare two text files online and visualize every difference instantly. This tool helps you review code, detect changes in configuration files, or verify document revisions with precision and speed. For specialized tasks, try our Online JSON Editor, JSON Compare, and Folder Diff tools, or use our Base64 decoder for data conversion.
Load or paste content for two separate files into dedicated editors. This allows for a direct, side-by-side comparison to highlight discrepancies.
Comparing two versions of a file is essential for code reviews, tracking document revisions, or identifying changes in configuration files.
Compare a new version of a script with its previous version to understand what changes were introduced.
Easily upload files by dragging and dropping them into the designated dropzones. This provides a quick and intuitive way to load your files for comparison.
Drag and drop functionality streamlines the file selection process, making it faster and more user-friendly than traditional file pickers.
Quickly compare two files by dragging them from your file explorer directly into the application.
Visualize differences between your files in a clear, intuitive side-by-side layout. Changes are highlighted with distinct colors for easy identification of additions, deletions, and modifications.
A visual diff makes it easy to quickly grasp the nature and extent of changes, improving review efficiency and reducing errors.
Alt+Z (Windows/Linux) or Cmd+Alt+Z (Mac).Review changes made to a configuration file by a colleague before merging them into the main branch.
Quickly locate specific text or patterns within your compared files using the intuitive search bar.
Efficiently find relevant sections or specific data points within large files without manual scanning.
Search for a specific variable name or function call across two versions of a code file.
Utilize powerful regular expressions (regex) and advanced filtering options to perform complex searches across your compared files, accessible via the Ctrl+F shortcut.
Pinpoint intricate patterns, specific data formats, or subtle discrepancies that simple text searches might miss.
Search for all email addresses or specific API endpoint changes across two large log files.
Effortlessly copy selected content or entire file sections from either editor to your clipboard with a single click.
Streamline data transfer for external use, documentation, or integrating changes into other development tools.
Copy a specific code block from the modified file to paste into your version control system's commit message.
Directly insert content from your system clipboard into either of the comparison editors.
Quickly load data for comparison without manual typing, file uploads, or navigating through local directories.
Paste a code snippet from a chat application into one editor and a local file's content into the other for a quick comparison.
The Trim Whitespace tool removes leading and trailing whitespace from each line of your file content, and collapses multiple spaces into a single space.
Whitespace differences can often be ignored in comparisons. This tool helps you focus on meaningful content changes by normalizing whitespace across both files.
Before comparing two code files that have been formatted differently, use Trim Whitespace to ignore formatting differences and focus on logic changes.
Easily clear both input editors and reset the comparison tool. Start a new comparison with fresh content at any time.
Provides a clean slate for new comparisons, preventing accidental mix-ups with previous data.
After completing a file comparison, clear the editors to prepare for comparing a different set of files.
A diff tool, short for “difference tool,” is a software utility that compares two text files and highlights the differences between them. These tools are widely used in software development, content writing, and configuration management to ensure accuracy between document versions.
JSON Workbench’s File Compare tool brings this capability online, offering a fast, privacy-focused way to perform comparisons without installing additional software.
The interface is designed to be intuitive and accessible even for non-developers who simply need to check text differences between two versions of a document.
No. JSON Workbench runs entirely in your browser using local processing. Your content never leaves your device.
Any text-based file: JSON, JavaScript, HTML, CSS, Python, YAML, Markdown, or plain text.
Yes. The side-by-side diff view helps developers review pull requests or local file changes before commits.
You can ignore formatting differences using the Trim Whitespace feature to focus on meaningful content changes.
Following these practices ensures cleaner, more consistent comparisons — especially when working with JSON or configuration files.
Unlike traditional tools that require installation, JSON Workbench runs directly in your browser with privacy-first design. It’s lightweight, accurate, and suitable for both developers and general users. Whether you’re auditing data, reviewing scripts, or comparing legal text, this tool offers clarity without complexity.
