Frequently Asked Questions
Everything you need to know about processing files securely in your browser
How does the CSV to JSON converter work?
It parses comma-separated values (CSV) or tab-separated values (TSV) text or files, extracts the headers from the first row, and transforms each subsequent row into a structured JSON array of objects.
Is my data safe when converting sensitive CSV files?
Yes, 100%. The conversion is performed purely client-side in your browser. No files are uploaded to any server, making it compliant with strict privacy requirements.
Can I customize the JSON output format?
Yes, you can choose delimiters like commas, semicolons, or tabs to correctly parse your tabular data, and then copy the formatted JSON array or download it as a .json file.
How do I handle CSV files that use delimiters other than commas?
The tool allows you to manually specify the delimiter (comma, semicolon, or tab) in the parsing configuration to ensure accurate parsing of various file types.
