Text Splitter / Joiner
Split a single string into multiple lines or join multiple lines into a single string using custom delimiters.
Split Options
Split Mode: Convert a single string (like apple,orange,banana) into a vertical list. Very helpful for cleaning up data exports or breadcrumbs.
Join Mode: Convert a vertical list of items into a single string separated by your choice of delimiter. Perfect for creating CSV output or SQL IN () parameters.
Why use a Text Splitter & Joiner Tool?
Data often arrives in a format that isn't quite right for your current needs. You might have a long string of tags separated by commas that you need as a vertical list, or a vertical list of emails that you need to convert into a single, semicolon-separated string for a mail merge. Manually reformatting these lists is prone to error and incredibly slow. Our Text Splitter & Joiner tool provides a dual-mode solution for these common tasks. In 'Split Mode', you can break down a single line of text into multiple lines using any custom character. In 'Join Mode', you can take multiple lines and merge them into a single string with your choice of separator. It’s an essential utility for developers, marketers, and anyone handling list-based data. As with all our tools, it runs completely on your local machine for total privacy.

Frequently Asked Questions
How do I convert a comma-separated list to a vertical list?
Set the tool to 'Split Mode', enter a comma (,) as the delimiter, and paste your text. The tool will instantly create a new line for every item.
Can I join lines using a space or tab?
Yes! In 'Join Mode', you can enter a space or use standard character representations to merge your list into a single line.
What does the 'Trim Items' option do?
It automatically cleans up each part by removing extra spaces. This is very useful when splitting strings like 'apple , orange' to get 'apple' and 'orange' instead of 'apple ' and ' orange'.
Is there a limit on the amount of text?
The tool can process thousands of items instantly. Your only limit is the memory available in your web browser.
