What Is Line Splitter?
Reviewing a pasted blob without line numbers means reviewers say 'the third one from the bottom' instead of 'line 47'. That's slow and error-prone.
Paste your text and get a numbered version back.
If you're handing off migration previews, you reference exact rows in runbooks. If you're triaging errors, you point at specific stack frames in chat. If you're reviewing code, you make pastes easy to discuss.
Frequently Asked Questions
Can I start from a number other than 1?
Yes, set the start index to align with the source file.
Tip: Useful when reviewing slices of larger files.
CRLF vs LF?
Both work. Output uses your system's default.
Tip: Cross-platform safe.
Are empty lines numbered?
Yes by default. Toggle skip-empties to omit them.
Tip: Skip for code reviews, keep for source-aligned numbering.
How does this differ from Text Splitter?
Both produce line output. Line Splitter also numbers and formats.
Tip: Text Splitter for non-newline delimiters.
What format is the numbering?
'1: content' by default. Configurable to brackets or fixed-width.
Tip: Use 001: padding for monospace docs.
Good for code review?
