About This Tool

The REST to GraphQL Converter convert rest api endpoints to graphql schemas with type inference and resolver generation. All processing happens client-side in your browser, ensuring your data remains private and secure. Perfect for developers who need quick, reliable processing without compromising on privacy or security.

How to Use This Tool

Paste REST Source Data

Enter the REST data you want to convert. The tool automatically validates your REST input and shows any syntax errors before conversion. Ensure your REST is valid for best results.

Configure Conversion Options

Adjust conversion settings like indentation, handling of REST-specific features, and GRAPHQL output style. Smart defaults work for most cases, but you can customize how REST structures map to GRAPHQL.

Review GRAPHQL Output

The converted GRAPHQL appears in real-time. Review carefully to ensure data integrity is maintained. Copy to clipboard or download the GRAPHQL file. Verify the output with our GRAPHQL validator if needed.

Technical Implementation

This tool is built using modern JavaScript and runs entirely in your web browser. All operations complete in milliseconds for typical inputs, with performance optimized for both speed and accuracy. The implementation is client-side only - your data never leaves your device. The tool works offline once loaded, requires no cookies, and includes no tracking. Supported browsers include Chrome 90+, Firefox 88+, Safari 14+, and Edge 90+. The tool is mobile-responsive and works on tablets and smartphones.

Best Practices & Tips

✓Validate input before conversion. Ensure your REST is valid before converting to GRAPHQL. Invalid REST often produces unexpected GRAPHQL results.
✓Review conversion results. Spot-check the GRAPHQL output to ensure data structure and values are preserved correctly. Pay special attention to nested objects and special characters.
✓Handle conversion edge cases. Test with empty values, null fields, special characters, and large datasets. REST-to-GRAPHQL conversion can have nuances that require attention.
✓Use related tools in sequence. After conversion, use our GRAPHQL formatter and validator to ensure the output is clean and valid. This creates a reliable conversion workflow.

Troubleshooting Common Issues

Problem: Conversion output is missing data or incorrect

Solution: First validate your REST input. Invalid REST often converts to incomplete GRAPHQL. Also check if the data structure is compatible - some REST features may not have GRAPHQL equivalents.

Example: REST comments or special attributes might not convert to GRAPHQL if GRAPHQL doesn't support those features.

Problem: Special characters appear corrupted after conversion

Solution: Ensure your REST uses proper character encoding (UTF-8). Special characters, emojis, or international text require consistent encoding throughout the conversion process.

Example: If you see � or garbled text, your source REST might not be UTF-8 encoded.
