FAQ Frequently Asked Questions

Can I convert both HTML tables and CSV data?
Yes, the tool handles both HTML table markup and CSV data input. Simply paste your content and the tool automatically detects the format and converts it to properly structured JSON data.
How does the tool handle table headers?
The converter automatically detects header rows and uses them as JSON object keys. If no headers are detected, it can generate generic field names or you can specify custom keys for your data structure.
Can I customize the JSON output structure?
Yes, you can choose between array of objects, nested structures, or other JSON formats depending on your needs. The tool provides options for how to structure the converted data.

The tool handles simple table structures best. Complex tables with merged cells, nested tables, or irregular structures may need manual cleanup or preprocessing before conversion for optimal results.
Can I use this for API development?
Absolutely! Converting tabular data to JSON is perfect for creating API endpoints, importing data into databases, or transforming data between different systems and applications.
