JSON Studio - Format, Validate & Transform (JSON, CSV, XML, YAML)
JSON Studio: The most powerful free tool for formatting, validating and transforming data. Auto-detect & convert JSON, CSV, XML, and YAML. Features AI-repair, Schema validation, and privacy-first processing.
Welcome to **JSON Studio**, the professional-grade workspace for all your data formatting and transformation needs. Unlike basic tools, JSON Studio automatically detects and converts between JSON, CSV, XML, and YAML. It features AI-powered structure repair, live schema validation, and advanced code generation—all processed entirely within your browser for complete privacy.
How to Use
- Paste your data (JSON, CSV, XML, or YAML) or drag and drop a file.
- JSON Studio automatically detects the format and converts non-JSON inputs to JSON.
- Use the "Auto-Fix" button to instantly repair syntax errors like missing trailing commas.
- Explore your data through the Interactive Tree View or use JSONPath for deep queries.
- Validate your results against a JSON Schema or generate a schema from your data.
- Export to your desired format: JSON, XLSX, CSV, XML, YAML, or PDF.
Features
- Multi-Format Input - Seamlessly handle JSON, CSV, XML, and YAML in one place.
- AI Syntax Repair - Heuristic engine fixes common data structure errors on the fly.
- Real-time Auto-Detect - No manual mode-switching; just paste and the tool adapts.
- Advanced Code Gen - Generate TypeScript, Zod, Python, Java, and Go from your data.
- Spreadsheet Integration - Export large datasets directly to Excel (.xlsx) or CSV.
- JSONPath & Schema Hub - Query complex objects and validate against standard schemas.
- Total Privacy - Every transformation happens client-side; your data is never uploaded.
Common Use Cases
- **Data Migration**: Converting legacy XML or CSV exports into modern JSON for APIs.
- **API Debugging**: Formatting and inspecting microservice payloads with live validation.
- **Development**: Generating type-safe interfaces (TypeScript/Zod) from sample data.
- **Reporting**: Transforming nested JSON data into flat CSV or XLSX for business analysis.
- **Learning**: Visualizing complex data structures via the interactive tree explorer.
Tips & Best Practices
Paste CSV data directly; JSON Studio will convert it to a JSON array of objects automatically.
Use the "Deep Search" feature to find and replace values across thousands of lines.
If your JSON is slightly broken, try the "AI Fix" before manual cleanup.
Download your transformation results directly to avoid copy-paste character encoding issues.
The tree view is editable—update values visually and watch the code update in real-time.
