How to convert CSV files in your browser
A data transfer often fails because the source and destination use different structures. For example, a JSON array uses objects and keys, while a CSV file uses rows and column headers. Choose the matching converter, add your data, and save the result. This method keeps the conversion focused on the formats you need.
- You can choose JSON to CSV, CSV to XLS, CSV to JSON, or CSV Viewer from this list.
- You can paste your data or add a file. The page processes the input in your browser.
- You can review the output, then copy or download it. A reverse converter can restore the other format when the structure supports it.
