Privacy note
Your text is processed in your browser. This tool does not store pasted text on a server.
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
- Paste text with extra spaces.
- Choose whether to collapse repeated internal spaces.
- Choose whether to remove empty lines.
- Run the tool and review the cleaned output.
Privacy and limitations
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.
