How it works

CRLF and LF input splits into rows, trimming runs first when selected, and each eligible row becomes prefix + row + suffix. The reconstructed output uses LF and counts only rows that actually received additions.

  • Both additions start empty, while trimming and skipping are off so no source characters disappear by default.
  • An empty final row from a trailing newline is treated like any other row unless skipped.

Worked example

Add prefix/suffix to lines
Add custom text before and after each line
Input
											Input: apple
banana
cherry
Prefix: - 
Suffix: ;
Output
												- apple;
- banana;
- cherry;

When to use this

SQL drafts gain -- comments, Markdown items gain dash prefixes, and batch-command filenames receive quotes or trailing delimiters.

Edge cases

  • A trailing newline creates one final empty row that receives the prefix and suffix when empty rows are included.
  • A spaces-only row is processed without trimming but becomes empty and skippable when trimming runs first.
  • Windows CRLF rows are rejoined with LF, so the visible text survives but original line-ending bytes do not.
