How to Use
- Prepare your JSON data:Ensure your JSON is formatted as an array of objects. Each object represents a row, and object properties become columns.
- Paste or type your JSON:Enter your JSON data in the input textarea. You can also click "Load Sample" to see an example or upload/drag & drop a JSON file.
- Configure options:
- Toggle "Include Headers" to add/remove column names
- Enable "Flatten Nested Objects" for complex JSON structures
- Select your preferred delimiter (comma, semicolon, tab, or pipe)
- Review the output:The CSV will be generated automatically in the output area.
- Export your data:Click "Download CSV" to save the file, or "Copy" to copy it to your clipboard.
💡 Pro Tips:
- • Use the sample data to understand the expected JSON format
- • For nested objects, try the "Flatten" option to create separate columns
- • Choose semicolon delimiter for Excel compatibility in some regions
- • Large datasets? Consider processing in smaller batches for better performance
⚠️ Common Issues & Solutions:
JSON parsing error: Unexpected token
Check for missing quotes, trailing commas, or invalid JSON syntax. Use the sample data as a reference.
Nested objects not flattening correctly
Enable the 'Flatten Nested Objects' option and ensure your JSON structure is consistent across all objects.
CSV output has extra columns
This happens when objects have different properties. Consider normalizing your JSON data first.
Special characters not displaying correctly
Ensure your JSON is properly encoded in UTF-8 and avoid using control characters.
