Remove Whitespace

Strips all whitespace characters (spaces, tabs, newlines) from any text string. Use via MCP in Cursor or Windsurf for cleaning user input, or call GET /v1/string/remove-whitespace with your text. Perfect for sanitizing data before validation or creating compact identifiers. Returns the exact input with every whitespace character removed.

FAQ

What types of whitespace does this remove?

Removes all Unicode whitespace: spaces, tabs, newlines, carriage returns, form feeds, and other whitespace characters like non-breaking spaces.

How do I use this with MCP in my AI coding assistant?

Call the remove_whitespace tool with your text parameter. Works in Cursor, Claude Code, Windsurf, and other MCP-compatible editors for instant text cleaning.

Does this preserve the original character encoding?

Yes, all non-whitespace characters remain unchanged including Unicode symbols, emojis, and special characters. Only whitespace is removed.

What's the difference between this and trim functions?

Trim only removes leading/trailing whitespace. This removes ALL whitespace throughout the entire string, including spaces between words.

Can I use this for creating URL-safe strings?

Partially - it removes spaces but doesn't handle other URL-unsafe characters. You'd need additional URL encoding for complete safety.
