Replace multiple spaces with a single space in text

How to use this calculator

1. Paste your text in the "Input Text" area. You can copy text from documents, emails, or web pages.
2. Optionally, check the "Preserve newlines" box if you want to keep line breaks intact in your output.
3. Click the "Calculate" button to process your text.
4. The normalized text will appear in the "Output Text" area, with multiple spaces replaced by single spaces.
5. Statistics about the word count and character count are automatically calculated.

Principle explanations

This calculator uses regular expressions to identify sequences of whitespace characters (including spaces, tabs, and newlines) and replaces them with a single space. The core JavaScript function used is:

// Replace multiple spaces with a single space
var normalized = text.replace(/\s+/g, ' ');
                

The regular expression \s+ matches one or more whitespace characters in sequence, and the g flag ensures that all such sequences throughout the text are replaced.

Use cases

• Cleaning up text data before processing it in applications
• Normalizing user input to prevent formatting issues
• Preparing text for display in user interfaces
• Creating consistent text formats for documentation
• Improving text searchability by eliminating excessive whitespace
