Text Separator
Runs entirely in your browser
Join a list of lines into a comma or custom delimited string, or split delimited text back into separate lines. Everything happens directly in your browser.
How to use Text Separator
- Paste your text — one item per line to join, or a delimited list to split.
- Choose a separator, and a wrapping style if you're joining.
- Click Join with separator or Split into lines.
- The result appears in the Output box — copy it with one click.
Features
- Join lines into a comma, semicolon, pipe or custom delimited string.
- Split delimited text back into one item per line.
- Optional quote or parenthesis wrapping for each item.
- 100% client-side — your text never leaves your browser.
Example
Joining this list, with the separator set to Comma and wrapping set to double quotes:
apple
banana
cherryproduces a ready-made SQL IN list:
"apple","banana","cherry"Splitting works the other way: paste red,green,blue with the separator set to Comma and click Split into lines to get:
red
green
blueTips for cleaner results
- When joining, blank lines in your input are skipped automatically — an accidental empty line between items won't produce an empty entry in the output.
- When splitting, each resulting item has its leading and trailing spaces trimmed, so "red, green, blue" splits cleanly into "red", "green" and "blue" even with spaces after the commas.
- A custom separator can be more than one character, such as " | " with spaces on each side — it's matched literally, not as a pattern.
- Choose New line as the separator to turn one long comma- or pipe-delimited string into a plain list, one item per line.
Is Text Separator safe?
Yes. Text Separator joins and splits your text locally, automatically skipping blank lines and trimming spaces as described above — none of it is sent to a server, and nothing is kept once you close or refresh the tab.
Frequently Asked Questions
What separators can I use?
Comma, comma with a space, semicolon, pipe, space, tab and new line are built in, or you can enter any custom separator.
Can I wrap each item in quotes?
Yes. When joining lines, you can wrap each item in double quotes, single quotes or parentheses, which is useful for building SQL IN lists or code arrays.
What does Split into lines do?
It takes a single line of delimited text, such as a comma-separated list, and breaks it into one item per line using the separator you choose.
