How Line Number Removal Works
Uses regex patterns anchored to the start of each line to remove numbering prefixes without touching inline digits.
Supports both automatic detection of standard numbering formats and user-defined custom regex input.
Processes each line independently for accuracy, even with mixed numbering styles.
All processing runs locally, ensuring privacy and zero data transmission.
