What is the JSON Converter?
The JSON Converter is a utility that instantly transforms complex JSON data into human-readable YAML or CSV formats compatible with Excel or databases. It's highly useful when you need to switch formats for data analysis, configuration editing, or log inspection.
Key Features
- Real-time Conversion: Results update instantly as you input JSON or change options.
- JSON to YAML: Cleanly transforms JSON objects into readable YAML with proper indentation.
- JSON to CSV: Converts JSON arrays into CSV files for Excel, with delimiter and header options.
- Automatic Flattening: Automatically flattens nested objects into dot-notated columns (e.g., user.name).
- Privacy Protected: Processing occurs only within your browser for complete data safety.
When Should You Use It?
- When you need to analyze API responses (JSON) in Excel or create reports.
- When migrating configuration files like Kubernetes or Docker Compose from JSON to YAML.
- When you want to visualize nested JSON structures in a flat table format.
Frequently Asked Questions (FAQ)
Can single-object JSON be converted to CSV?
Yes, a single object is treated as a single row. For arrays, each element becomes a row.
Can it handle large JSON files?
For stable browser performance, we recommend data within 100,000 characters. Larger data may result in slower processing.
What is the encoding of the downloaded file?
Files are downloaded using UTF-8 (with BOM) encoding to ensure non-English characters display correctly in Excel.
