Keyboard Shortcuts
Use Ctrl+A (Cmd+A on Mac) to select all formatted JSON, then Ctrl+C to copy. This is faster than clicking the copy button for large JSON files.
Validate API Responses
Paste API responses directly from your browser's Network tab to quickly validate structure and identify issues. This is especially useful when debugging REST APIs or GraphQL queries.
Compare JSON Objects
Format two JSON objects side-by-side in separate browser tabs to easily spot differences in data structure or values. This helps when comparing API versions or test data.
Minify for Production
Use the minify option to remove whitespace and reduce file size when deploying JSON configuration files. This can reduce bandwidth usage by 30-50% for large config files.
Handle Large Files
For JSON files over 1MB, consider splitting them into smaller chunks or using the browser's built-in search (Ctrl+F) to find specific keys without scrolling through thousands of lines.
SQL Formatter
Format and beautify SQL queries with proper indentation.
SQL Validator
Validate SQL queries across multiple dialects with intelligent error detection and auto-fix suggestions.
Regex Tester
Test and debug regular expressions with live highlighting.
Data Format Converter
Convert between JSON, YAML, and XML formats with real-time validation.
