Comma Separator
Convert line-separated text to comma-separated values or split delimited data into lines with custom delimiters.
Comma Separator
The Comma Separator converts line-separated lists into delimited text and splits delimited values back into lines. Use it to prepare CSV data, clean up copied lists, or reformat text for spreadsheets and scripts. Related tools: Remove Line Breaks, Sort Text Lines, and Remove Duplicate Lines.
How It Works
Enter one item per line in the left panel to join them with your chosen delimiter. Edit the delimited output on the right to split values back into separate lines. The default delimiter is a comma, but you can use tabs, semicolons, pipes, or any custom string.
Common Use Cases
- Convert a vertical list of emails into a comma-separated string for mail merge
- Split a CSV row into individual lines for editing
- Prepare data for import into Excel, Google Sheets, or databases
- Reformat tags, keywords, or IDs between line and delimited formats
Frequently Asked Questions
What is a delimiter?
A delimiter is a character or string that separates values in a list. The comma is the most common delimiter, but tabs, semicolons, and pipes are also widely used.
Can I use a custom delimiter?
Yes. Enter any character or string in the Delimiter field. For example, use a pipe (|) to create values like apple|banana|cherry.
What are comma-separated values (CSV)?
CSV is a plain text format where each row contains values separated by commas. CSV files can be opened directly in Excel and most spreadsheet applications.
Does the tool trim whitespace?
Yes. Leading and trailing whitespace is removed from each item during conversion. Empty lines and empty values are skipped.
Can I convert in both directions?
Yes. Edit the lines textarea to generate delimited text, or edit the delimited output to split values back into lines. Conversion updates in real time.
What if my data contains the delimiter character?
If values themselves contain the delimiter (e.g., commas inside names), wrap those values in quotes before processing, or choose a delimiter that does not appear in your data.
