Strip Line Numbers from Text The Strip Line Numbers tool removes leading numeric prefixes from text — cleaning up content copied from PDFs, documentation, e-books, and numbered code snippets. Pattern matching uses the ECMAScript regular expression specification for precise numeric prefix detection. The PDF specification (ISO 32000) explains why PDF documents embed line numbers in exported text — they are part of the rendered layout. --- The Problem with Copy-Pasted Numbered Text Text copied from PDFs, printed documentation, and some code sharing sites arrives with line numbers embedded. These numbers interfere with downstream processing: If you paste this into a word processor, the numbers become part of the content. If you feed it to a script, the numbers corrupt your data.

Frequently Asked Questions
How do I remove line numbers from text?
Paste the numbered text into the Strip Line Numbers tool and click Strip. The tool detects leading numeric patterns (1., 1:, 1), 1 ) and removes them from every line, leaving clean content.
How do I strip leading whitespace from lines?
Enable the Trim Whitespace option. After stripping the numeric pattern, any remaining leading and trailing spaces are removed. This cleans up the extra indentation that often follows a line number.
How do I remove numbering from a list?
Paste your numbered list into the tool. Patterns like '1.', '2.', '10.' with any common separator are detected and stripped automatically. The separator types supported are period, colon, parenthesis, and space.
How do I clean text copied from a PDF?
PDF text extraction often introduces line numbers, page numbers, and extra whitespace. Paste the extracted text, run Strip Line Numbers to remove the numbers, then use the Wrap Text tool to rejoin paragraph breaks inserted by the PDF renderer.
How do I remove line numbers with regex?
Use the Find and Replace tool with Regex mode. Pattern: ^\s*\d+[.:\)\s]\s* — this matches optional leading whitespace, one or more digits, a separator character, and trailing whitespace. Set replacement to empty.
