Frequently Asked Questions
- Are these online converters safe for sensitive data?
- Yes. Every converter runs entirely in your browser using JavaScript. Your data is never sent to a server, stored, or logged. You can verify this by disconnecting from the internet — the tools will still work.
- Which converter should I use for spreadsheet data?
- Use the CSV to JSON converter to transform tabular data into structured JSON, or the JSON to CSV converter to go the other way. Both handle nested objects, custom delimiters, and large files.
- Can I convert between multiple formats in one step?
- Each tool handles one conversion direction. For multi-step conversions (e.g., XML → JSON → YAML), run the tools in sequence — the output of one can be pasted directly into the next.
- Is there a file size limit?
- Since all processing happens in your browser, limits depend on your device memory. Most tools handle files up to 10 MB without issues. For very large files, consider splitting them into smaller chunks.
