FORMAT GUIDE
How to convert delimiters and list formats reliably
These notes explain how the tool changes delimiters, wrappers, and prefixes while preserving item order and content.Vertical and inline lists
Turn one-item-per-line text into a comma list or convert comma-separated text back into separate lines.
Spreadsheet copied values
Convert tab-separated values copied from spreadsheets into new lines, commas, pipes, or another delimiter.
Service-specific formats
Use semicolons, pipes, or your own literal string as either the source or target delimiter.
Code and list helpers
Wrap each item with single or double quotes. Matching quote characters inside items are escaped with a deterministic rule.
Document-ready lists
Add numbers, bullets, or hyphens to make newline output easier to paste into documents and chat.
Keep order and item text
This tool does not sort, deduplicate, search, or replace text. Only the selected trim, empty, wrapper, and prefix rules are applied.
IMPORTANT NOTES
Important notes
- Custom delimiters are treated as literal strings, not regular expressions.
- Quote mode is not a complete CSV serializer and does not guarantee SQL safety.
- Numbers and bullets are most natural with newline output, but other target delimiters still show the exact selected result.
- Service limits remain candidate values until the main workspace approval gate is completed.
FAQ
Frequently asked questions
01What happens to empty values between delimiters?+
They are removed when Remove empty items is enabled and preserved when it is disabled.
02Are spaces trimmed automatically?+
Only when Trim item edges is enabled, using JavaScript trim semantics.
03Can I use .* as a custom delimiter?+
Yes. Custom delimiters are literal strings, so regex metacharacters are not interpreted.
04What if an item already contains the same quote character?+
It is preserved by doubling the matching quote character before wrapping the item.
05Does this tool sort or remove duplicates?+
No. Sorting and deduplication belong to tool 039; tool 040 focuses on delimiter and list formatting.
