Frequently Asked Questions

What types of separators does this tool support?
The tool automatically detects and converts the following separators to commas:
  • Spaces (apple banana cherry → apple,banana,cherry)
  • Tabs (useful when pasting from Excel or Word)
  • New lines (each line becomes a comma-separated item)
  • Mixed separators (it will handle combinations of the above)
Can I use this tool with numbers and special characters?
Absolutely! The comma separator tool works with:
  • Numbers (1 2 3 → 1,2,3)
  • Special characters (#, @, $, etc.)
  • Mixed content (text with numbers and symbols)
  • Foreign language characters and Unicode
The tool preserves all characters exactly as you enter them, only changing the separators.
Will this tool work with CSV or Excel data?
Yes, it's perfect for preparing CSV data! Here's how to use it with Excel/CSV:
  • Copy a column from Excel and paste it into the tool - it will convert to comma-separated
  • For multi-column CSV data, process one column at a time
  • Works with tab-separated values (common in CSV exports)
The formatted output is ready to paste back into Excel or use in SQL queries.
Is there a limit to the amount of text I can process?
The tool can handle:
  • Thousands of items at once (tested with 10,000+ items)
  • Large text blocks (up to 1MB of data, about 200,000 words)
  • Performance remains fast even with large inputs
For best results with very large datasets, consider processing in batches of a few thousand items at a time.
Can I customize the separator (use something other than commas)?
The current version is optimized for comma separation, but we're working on adding:
  • Custom separator options (semicolons, pipes, etc.) in a future update
  • Advanced formatting options for developers
  • Batch processing features for large datasets
For now, you can easily replace commas with other characters after generation.
Is my data secure when using this tool?
Your data never leaves your browser! This tool is:
  • 100% client-side processing (no server communication)
  • No data storage or logging of your content
  • Safe for sensitive information (processes locally in your browser)
You can even use it offline after loading the page once.
