What is Text Line Joiner?

Text Line Joiner is a tool for combining multiple lines of text into a single line. It is useful when you want to turn a line-based list into a delimiter-separated string.

You can choose the delimiter, trim whitespace from each line, and ignore empty lines. The result updates automatically.

How to Use

1. Enter multiple lines of text.
2. Set the delimiter.
3. Toggle whitespace trimming or empty-line handling if needed.
4. Review the joined one-line result.

Main Settings

Delimiter

This is the text inserted between lines. You can use values such as ,, , , or a space depending on the output you need.

Trim Whitespace from Lines

This removes leading and trailing spaces from each line before joining. It is useful for cleaning pasted lists.

Ignore Empty Lines

This skips blank lines so they do not affect the joined result.

Use Cases

• Turning a line-based list into comma-separated text
• Preparing one-line values for arrays or arguments
• Joining copied multi-line data into a single string
• Cleaning whitespace and blank lines while combining text

Input and Output Example

Tokyo
Osaka
Nagoya
Fukuoka

With , as the delimiter, this becomes:

Tokyo,Osaka,Nagoya,Fukuoka

Things to Keep in Mind

• The delimiter choice affects whether the output is ready for direct reuse
• If whitespace trimming is enabled, line-edge spaces are not preserved
• If empty-line ignoring is disabled, blank lines also affect the final output
