Input Two JSON Objects
Load or paste content for two separate JSON objects into dedicated editors. This allows for a direct, side-by-side comparison to highlight discrepancies.
Why it matters
Comparing two versions of a JSON object is essential for code reviews, tracking document revisions, or identifying changes in configuration files.
Advantages
- Direct Comparison: See both versions simultaneously.
- Flexible Input: Supports both pasting text and loading files.
- Accuracy: Ensures no change goes unnoticed.
Use case
Compare a new version of a JSON configuration with its previous version to understand what changes were introduced.
Drag and Drop
Easily upload JSON files by dragging and dropping them into the designated dropzones. This provides a quick and intuitive way to load your files for comparison.
Why it matters
Drag and drop functionality streamlines the file selection process, making it faster and more user-friendly than traditional file pickers.
Advantages
- Intuitive Interface: Simplifies the file upload process.
- Time-Saving: Quickly load files without navigating through file dialogs.
- Enhanced User Experience: Provides a modern and efficient workflow.
Use case
Quickly compare two JSON files by dragging them from your file explorer directly into the application.
Side-by-Side Diff
Visualize differences between your JSON objects in a clear, intuitive side-by-side layout. Changes are highlighted with distinct colors for easy identification of additions, deletions, and modifications.
Why it matters
A visual diff makes it easy to quickly grasp the nature and extent of changes, improving review efficiency and reducing errors.
Advantages
- Visual Clarity: Color-coded highlights for different change types.
- Intuitive Layout: Easy to follow changes line by line.
- Comprehensive Overview: Get a full picture of all modifications.
- Word Wrap: For improved readability of long lines, toggle word wrap using
Alt+Z(Windows/Linux) orCmd+Alt+Z(Mac).
Use case
Review changes made to a JSON configuration file by a colleague before merging them into the main branch.
Simple Search
Quickly locate specific text or patterns within your compared JSON objects using the intuitive search bar.
Why it matters
Efficiently find relevant sections or specific data points within large JSON objects without manual scanning.
Advantages
- Instant Results: Find matches as you type.
- Dual Editor Search: Search across both original and modified JSON objects.
Use case
Search for a specific key name or value across two versions of a JSON file.
Advanced Search
Utilize powerful regular expressions (regex) and advanced filtering options to perform complex searches across your compared JSON objects, accessible via the Ctrl+F shortcut.
Why it matters
Pinpoint intricate patterns, specific data formats, or subtle discrepancies that simple text searches might miss.
Advantages
- Pattern Matching: Use regex for flexible and powerful searches.
- Granular Control: Refine your search with various filtering options.
Use case
Search for all email addresses or specific API endpoint changes across two large JSON files.
Copy to Clipboard
Effortlessly copy selected content or entire JSON objects from either editor to your clipboard with a single click.
Why it matters
Streamline data transfer for external use, documentation, or integrating changes into other development tools.
Advantages
- Quick Transfer: Instantly copy data for reuse.
- Accuracy: Avoid manual transcription errors.
Use case
Copy a specific JSON object from the modified file to paste into your version control system's commit message.
Paste from Clipboard
Directly insert content from your system clipboard into either of the comparison editors.
Why it matters
Quickly load data for comparison without manual typing, file uploads, or navigating through local directories.
Advantages
- Instant Input: Load content directly from clipboard.
- Convenience: Ideal for comparing snippets or data from other applications.
Use case
Paste a JSON object from a chat application into one editor and a local file's content into the other for a quick comparison.
Format JSON
The Format JSON tool automatically beautifies raw JSON data, transforming it into a clean, indented structure that's easier to read and debug.
Why it matters
Unformatted JSON is hard to scan, especially with nested objects. Formatting improves readability and makes errors easier to catch.
Advantages
- Readability: Indented JSON is easier to navigate.
- Debugging: Quickly spot missing commas or brackets.
- Collaboration: Share cleaner data with teammates.
Use case
When working with an API response that comes as a single line, paste it in and instantly format it for inspection.
Minify JSON
The Minify JSON tool compresses JSON data by stripping whitespace, line breaks, and comments.
Why it matters
Minified JSON reduces file size, which improves transfer speed and saves bandwidth.
Advantages
- Performance: Faster API responses with smaller payloads.
- Efficiency: Less bandwidth usage in client-server communication.
- Storage: Reduced disk space usage for large datasets.
Use case
Before deploying config files in production, minify them to optimize size without losing data.
Trim Whitespace
The Trim Whitespace tool removes leading and trailing whitespace from each line of your file content, and collapses multiple spaces into a single space.
Why it matters
Whitespace differences can often be ignored in comparisons. This tool helps you focus on meaningful content changes by normalizing whitespace across both files.
Advantages
- Noise Reduction: Eliminates irrelevant whitespace differences.
- Improved Clarity: Focus on the actual content changes that matter.
- Consistency: Ensures a consistent whitespace format across files.
Use case
Before comparing two code files that have been formatted differently, use Trim Whitespace to ignore formatting differences and focus on logic changes.
Clear & Reset Editors
Easily clear both input editors and reset the comparison tool. Start a new comparison with fresh content at any time.
Why it matters
Provides a clean slate for new comparisons, preventing accidental mix-ups with previous data.
Advantages
- Fresh Start: Begin each comparison without residual data.
- User-Friendly: Simple one-click action to prepare for a new task.
Use case
After completing a file comparison, clear the editors to prepare for comparing a different set of files.
