What splitting text does
Splitting text breaks a single block of text into separate pieces wherever a chosen delimiter appears, putting each piece on its own line. The classic case is turning comma-separated values into a clean vertical list — "apple, banana, cherry" becomes three lines. You choose what to split on, and the tool divides the text accordingly. It is the counterpart to joining lines, and essential for reshaping data.
Common splitting tasks
The need arises constantly when data comes in the wrong shape. You have a comma-separated string and need it as a list to process line by line. You have text with items separated by semicolons, pipes, tabs, or some other character, and need them separated. You are converting a single-line export into rows. You want to break a sentence into words by splitting on spaces. Any time your data is packed into one line with a separator and you need it broken out, splitting does it in one step.
Choosing your delimiter
The delimiter is the character or string that marks where to split. A comma is the most common, but you can split on a semicolon, a space, a tab, a pipe, or any custom character or word. This flexibility lets you handle whatever format your data arrived in. There is also an option to trim each resulting piece, which removes any leading or trailing spaces — useful because comma-separated data often has a space after each comma that you do not want in the result.
Splitting and joining together
Splitting and joining are two halves of reshaping text between a delimited string and a list. Split turns a delimited line into separate lines; join turns separate lines back into a delimited string. Together they let you convert data between formats — take a comma-separated string, split it to a list, clean or sort the list, then join it back with a different separator. Both run entirely in your browser, so your data stays private throughout.
Privacy: your text never leaves the browser
All processing happens locally, on your own device. Your text is never sent to servers, which makes the tool safe even for confidential content. When you close the tab, nothing remains stored.
