How do I add text to the beginning or end of every line?
Choose the Add Prefix, Add Suffix, or Add Both operation, type the text you want in the Prefix and/or Suffix field, then click Process Text to apply it to every line of your input.
How do I remove a prefix or suffix from multiple lines at once?
Select Remove Prefix, Remove Suffix, or Remove Both, enter the exact text to strip (such as "www." or ".txt"), and the tool deletes that text from the start or end of each line.
Is removing a prefix case sensitive?
By default removal matches case exactly, but you can enable the "Case sensitive" option to control whether "WWW." and "www." are treated as the same text when removing.
Will the tool remove a prefix from blank lines?
If "Skip empty lines" is enabled, blank lines are left untouched; otherwise the operation still applies to them, which can add unwanted prefixes or suffixes to empty rows.
Can I add a prefix and suffix to the same lines in one step?
Yes, choose the "Prefix & Suffix" or "Add Both" operation to apply both a prefix and a suffix to every line in a single processing pass.
