When this tool helps

Use this tool when copied lines contain unwanted spaces before or after each value.

It is useful before deduplication, sorting, spreadsheet import, keyword list cleanup, or matching text values between tools.

Common cleanup options

Leading spaces

Remove accidental indentation before list values, keywords, names, or exported fields.

Trailing spaces

Clean hidden spaces that can break matching, imports, or comparison work.

Internal spaces

Optionally collapse repeated spaces inside each line.

Line order

The tool keeps the original order unless you use a separate sorting tool.

How to use it

  1. Paste text with extra spaces.
  2. Choose whether to collapse repeated internal spaces.
  3. Choose whether to remove empty lines.
  4. Run the tool and review the cleaned output.

Privacy, review, and limitations

The current version processes pasted text in your browser for normal use, and the page explains the tool behavior that is visible in the interface. Review the preview before copying output into another workflow, especially when the source text came from PDFs, spreadsheets, exports, or copied tables.

Trimming is text-based and does not validate whether a value is correct.

Intentional indentation should be reviewed before trimming source code, outlines, or formatted text.
