Whitespace Cleaner

Cleaned the text, removing 10 character(s).

How it works

• Normalised CRLF and lone CR line endings to LF.
• Expanded each tab to 2 space(s).
• Collapsed runs of two or more spaces to one.
• Trimmed leading and trailing whitespace on every line.
• Dropped lines that were empty after trimming.

• Only whitespace is changed; other characters are preserved exactly.
• The clean-up is idempotent for a fixed option set.

Methodology

1. Normalise CRLF and lone CR to LF.
2. Expand tabs to the chosen number of spaces, or keep them when the width is zero.
3. Collapse runs of two or more spaces into one when space collapsing is enabled.
4. Trim leading and trailing whitespace on each line when line trimming is enabled.
5. Remove lines that are empty after trimming when blank-line removal is enabled.

Usage

1. Paste the text to clean.
2. Choose which whitespace operations to apply.
3. Run the tool and copy the cleaned text.

Examples

These are examples, not current values: they use fixed inputs, while the interactive tool computes live results in your browser.

Collapse and trim

{
  "text": "  hello   world  \n\n  next line ",
  "trimLines": true,
  "collapseSpaces": true,
  "removeBlankLines": true,
  "tabWidth": 2
}

Expand tabs

{
  "text": "a\tb",
  "trimLines": false,
  "collapseSpaces": false,
  "removeBlankLines": false,
  "tabWidth": 4
}

Trim only

{
  "text": "  keep   inner  spaces  ",
  "trimLines": true,
  "collapseSpaces": false,
  "removeBlankLines": false,
  "tabWidth": 0
}

Limitations

Pasted text carries formatting

Text copied from a document editor often mixes tabs, non-breaking spacing and trailing spaces. Cleaning it reproducibly makes diffs and downstream processing predictable.
