Quick Answer

Normalize whitespace by trimming line edges, converting tabs, collapsing repeated spaces, and reducing repeated blank lines. Use conservative settings when paragraph structure matters.

What Problem This Solves

Different sources use whitespace differently. PDFs, spreadsheets, websites, and documents can create inconsistent tabs, spaces, and blank lines that make text difficult to process.

The goal is to make spacing predictable without removing meaningful structure such as paragraphs, lists, or indentation that should remain.

Before and After Example

Here is a simplified example of whitespace cleanup.

Before
