How to use

  1. Select your target operation: Clean Whitespace, Remove Blank Lines, Multi-line to Single-line, or Single-line to Multi-line.
  2. Configure options to trim line edges, collapse multiple spaces, or strip non-printable ASCII control bytes.
  3. Choose a delimiter if joining or splitting lines (space, comma, comma-space, semicolon, pipe).
  4. Paste your text into the input pane and click Run.
  5. Click Swap at any time to invert between multi-line and single-line conversions.

Edge cases

Preserving Meaningful Code Indentation

When cleaning source code or indented configuration files, use the Remove Blank Lines operation rather than Clean Whitespace to strip empty lines without erasing leading indentation tabs or spaces.

Control Characters and Hidden Bytes

Copy-pasting text from PDFs, legacy terminals, or Word documents often introduces non-printable control characters (such as null bytes 0x00 or bell 0x07). Enabling Strip Non-Printable ASCII purges these hidden characters while preserving valid tabs and line feeds.

Flexible Delimiter Splitting

The Single-line to Multi-line operation tolerates irregular spacing around delimiters (such as 'a, b, c'), producing clean, uniformly trimmed lines.

How it works

  1. Scans text using regular expressions to collapse repeated spaces and tabs into single spaces without mangling newline breaks.
  2. Filters line arrays to prune lines containing only whitespace or zero characters.
  3. Joins or tokenizes lists using the selected delimiter token (comma, semicolon, pipe, or space).
  4. Runs entirely within an isolated browser Web Worker without any remote server communication.

Frequently asked questions

What does collapsing multiple spaces mean?

Collapsing spaces replaces two or more consecutive spaces or tabs between words with a single space, removing accidental gaps created during text copying or OCR scanning.

Does this tool normalize Windows and Unix line endings?

Yes. Both CRLF (\r\n) and LF (\n) line breaks are parsed consistently and normalized to clean standard line breaks.

Is my text transmitted over the internet?

No. All cleaning, trimming, and line joining takes place 100% locally in your web browser memory.
