Join text lines with a custom separator
Remove empty lines when joining text
Prepare line-based data for spreadsheets and lists
Convert text lines in your browser without installing software
Copy or download your converted text
Features explained
Custom separator
Set the separator string used between lines. The configured default is a semicolon, and you can replace it with a comma, a comma and space, or another string.
Skip empty lines
The skipEmpty option is enabled by default. Lines whose trimmed content is empty are omitted. When disabled, empty lines remain in the sequence used to build the output.
Copy to clipboard
Use the Copy button to copy the converted text. The interface also has a Copied! label for its copied state.
Download output
Use Download to save the converted text. The supplied code does not establish the file extension, file name, or encoding.
Load an example
Select Load Example to try sample input before using your own list.
Clear text
Use Clear to reset the current text in the workbench.
Client-side conversion
The conversion logic runs on the client side. The supplied analysis does not show a fetch or API call for this processing mode.
What can you use it for?
Make a comma separated list of names
Join names entered on separate lines into a single list for a form or text field that expects separated values.
Convert keywords for SEO research
Combine line-separated search terms into one string using a comma or another separator accepted by your research workflow.
Join product names and tags
Turn one-item-per-line product names, labels, or tags into a compact separated string for copying into another tool.
Prepare values for spreadsheets
Join text values before moving them into a field that expects one separated line. Confirm the destination's separator requirements first.
Clean a list before pasting
Skip blank or whitespace-only lines to avoid generating empty entries between retained values.

Benefits
- Join multiple lines into one separated string in a single conversion.
- Choose a separator that matches the field where you plan to paste the result.
- Skip blank and whitespace-only lines with the default setting.
- Copy or download the generated text using the available controls.
- Try Load Example before processing your own data.
Limitations
- The default separator is a semicolon, not a comma.
- The tool does not provide a separate trim-items option in the documented linesToComma processing mode.
- It joins text without validating CSV rules or escaping commas and quotation marks inside values.
- The output is plain joined text; structured file formats are not confirmed.
- The supplied code does not establish a maximum input length or a specific download file name.
- Client-side processing does not, by itself, establish how the surrounding website handles analytics or other data.
How your text is processed
The linesToComma conversion is performed on the client side. The supplied processing code shows no fetch or API call for this operation. This describes the conversion logic only; it does not establish the behavior of analytics, logging, browser extensions, or other parts of the website.
Tips
- Change the separator from the default semicolon to a comma if your destination expects comma separated values.
- Use a comma followed by a space when you want a more readable list.
- Keep skipEmpty enabled when blank lines should not produce empty entries.
- Inspect values that already contain commas before using the result as CSV data.
- Try Load Example to understand the conversion, then use Clear before entering a new list if needed.
Frequently asked questions
How do I convert lines to comma separated text online?
Paste your lines into Input lines, choose a comma in Options, and review Converted text. The tool joins the retained lines using your chosen separator. The default is a semicolon, so change it if you specifically need commas.
Can I change the separator from a semicolon to a comma?
Yes. The separator is configurable. Replace the default semicolon with a comma, comma and space, or another string. Every retained line is joined using that separator exactly as configured.
Does the converter skip blank lines automatically?
Yes. The configured skipEmpty option is enabled by default. It removes lines whose trimmed content is empty from the joining operation. It does not trim leading or trailing spaces from lines that contain actual text.
Can I join lines using a vertical bar or semicolon?
Yes. The separator accepts a string, so you can use a vertical bar, semicolon, comma, or another separator. The output uses the configured string between retained lines.
How do I convert a list of names into one line?
Paste each name on its own line, choose the separator you want, and inspect the output. For example, Alice, Bob, and Charlie can become one comma-separated string. Empty names or blank lines are handled according to skipEmpty.
Can I use this tool to prepare keywords for SEO?
Yes. Paste one keyword per line and choose a comma or another separator that your destination accepts. The converter joins the terms but does not research keywords, check search volume, or validate the resulting list.
Does this line converter upload my text to an API?
No API call is shown in the supplied conversion logic. The linesToComma operation runs on the client side. This does not independently verify how the rest of the website handles analytics, logging, or other browser activity.
Can I copy or download the converted text?
Yes. Use Copy to copy the output or Download to save it as a file. The interface also includes Load Example and Clear. The supplied code does not establish the downloaded file's name or extension.
Does the converter automatically create a valid CSV file?
No. It joins lines with the separator you choose, but it does not validate CSV syntax or escape values containing commas or quotation marks. If you need a standards-compliant CSV file, check and format those values separately.
Is there a maximum number of lines I can convert?
The supplied processing logic does not specify a maximum number of lines or characters. Actual practical limits may depend on the browser and the surrounding application, so a guaranteed unlimited input size cannot be confirmed.
