Frequently Asked Questions
What's the difference between "Collapse whitespace" and "Remove whitespace"?
Collapse whitespace replaces multiple consecutive spaces, tabs, and newlines with single spaces, keeping text readable. Remove whitespace eliminates ALL whitespace characters completely, resulting in continuous text without any spaces.
How does "Unique lines" work?
Unique lines removes duplicate lines while preserving the original order of first occurrence. It performs case-sensitive comparison, so "Apple" and "apple" are treated as different lines.
Can I use "Extract numbers" on financial data?
Yes, it extracts all numeric values including decimals (12.34), negative numbers (-5), and numbers with commas (1,000). However, it returns just the numbers - you may need to preserve context separately.
What does "Lines → JS array" do?
It converts line-separated text into a JavaScript array format: ["line1", "line2", "line3"]. Perfect for generating array literals in code, converting lists to JSON arrays, or preparing data for JavaScript applications.
Will "Strip Markdown" remove all formatting?
It removes common Markdown syntax like headers (#), bold (**), italic (*), links ([]()), code blocks (```), and images (![]()), but preserves the actual text content. Perfect for converting markdown documents to plain text.
