How to Use the Batch Line Operations Tool

Operation options:

  • Insert:
    Add a prefix or suffix to each line. Choose whether to insert your text at the beginning (prefix) or end (suffix) of each line, and optionally specify the starting column. You can use \n in your insert text to add a line break.

  • Remove before/after delimiter:
    For every line, remove everything that appears before or after a specified delimiter. You can use \n as your delimiter to represent a line break.

  • Trim lines:
    Remove any spaces or tabs at the beginning and end of each line.

  • Collapse multiple spaces:
    Replace any sequence of two or more spaces with a single space in each line.

  • Remove blank lines:
    Delete lines that are completely empty or contain only whitespace.

  • Remove lines containing:
    Delete all lines that contain the specified text. You can use \n to match line breaks.

  • Keep only lines containing:
    Keep only the lines that contain your specified text. All other lines will be removed. You can use \n to match line breaks.

Tip:

Whenever you type \n (backslash + n) in any field, it will be treated as a real line break during processing.
This allows you to insert or match actual line breaks, not just the characters “\” and “n”.
