Remove Line Numbers
Remove Line Numbers applies ^\s*\d+[.):\-]\s* to every line. It removes optional leading whitespace, one or more digits, one delimiter among ), ., :, or -, and optional following whitespace. It can therefore remove meaningful numeric prefixes such as dates or identifiers, but does not handle brackets, padded labels without those delimiters, roman numerals, nested numbering, or numbers without punctuation.

Prefix heuristics can remove real data
A regex cannot know whether '2026- report' is a line number or meaningful content.
How it works
CRLF is normalized; each line receives one anchored regex replacement; LF rejoins.
Key concepts
Anchored at line start
Numbers later in the line remain.
Whitespace included
Indentation before the number is also removed.
When to use it
- Strip simple '1. ' list numbering.
- Remove '42) ' or '7: ' prefixes.
- Clean a reviewed numbered excerpt.
When not to use it
- Do not run blindly on date/ID-leading data.
- Do not expect roman or bracketed formats.
- Do not expect multiple nested prefixes removed.

Common mistakes
Removing IDs
Numeric-dash prefixes match. Correction: Review input or use a stricter rule.
Expecting [1]
Brackets are unsupported. Correction: Use Find/Replace regex elsewhere.
Nested list
Only one prefix pass. Correction: Repeat deliberately or parse lists.
Best practices
- Test on representative lines.
- Keep source.
- Use a domain-specific prefix pattern for important data.
