CSV is a tabular data format, while JSON is a hierarchical key-value format. This tool bridges the gap by converting each row of the CSV into a JSON object, with the column headers serving as the keys.
What if my CSV doesn't have a header row?
The tool will use the first row as headers by default. If you need to handle CSVs without headers, that's a great suggestion for a future feature!
Does it handle commas inside quotes?
Yes, it correctly parses fields that contain commas, as long as they are properly quoted.
Is there a file size limit?
Since the conversion happens in your browser, very large files may be limited by your browser's memory.
All calculations and data processing for this tool are performed locally in your browser. We do not send any of your data to our servers, ensuring your information remains private and secure.
