Frequently Asked Questions

What does Trim Lines do?

It removes a specified prefix from the start and a specified suffix from the end of every line in your text. This is useful for cleaning up lists, JSON entries, and other structured data.

Does it remove the prefix/suffix from every line?

It only removes the prefix if a line actually starts with it, and only removes the suffix if a line actually ends with it. Lines that do not match are left unchanged.

Can I use it to clean JSON array entries?

Yes! If you paste lines like "apple", you can set prefix to " and suffix to ", to get clean values like apple.

What does "Trim whitespace first" do?

When enabled, each line is trimmed of leading and trailing spaces before the prefix and suffix are checked and removed. This helps when lines have inconsistent indentation.

Is my text stored anywhere?

No. All processing happens in your browser. Your text is never sent to any server.

Can I remove numbered prefixes like "1. " from every line?

You can remove a fixed prefix like "- " or "* ", but since numbered prefixes differ on each line (1., 2., 3...), you would need a regex tool for that. This tool removes the same prefix from every line.
