Frequently Asked Questions
What is the Text Splitter tool?
Text Splitter is a free online tool that breaks text into smaller parts using various methods. You can split by a specific delimiter (like comma or pipe), by fixed character length, by regex pattern, by lines, or by words.
How do I split by a custom delimiter?
Select "By Delimiter" mode and enter your delimiter in the text field. You can use any character or string as a delimiter. For special characters, use escape sequences like \n for newline or \t for tab.
What regex patterns can I use?
The tool supports standard JavaScript regex patterns. Common examples: \s+ (one or more whitespace), \d+ (one or more digits), [,;:] (any of comma, semicolon, or colon). Invalid patterns will show an error message.
What does "Keep Delimiter" do?
When enabled, the delimiter is kept attached to each part instead of being removed. For example, splitting "a,b,c" by comma with Keep Delimiter gives ["a,", "b,", "c"] instead of ["a", "b", "c"].
Is my data secure?
Yes! All processing happens directly in your browser using JavaScript. Your text is never sent to any server, making it completely private and secure for sensitive data.
