**TLDR:** The process of standardizing raw text at the spelling, formatting, and character levels to make it more consistent and processable.

<p>Text normalization is one of the most critical early steps in an NLP pipeline. Inconsistencies in casing, unnecessary whitespace, punctuation variants, character irregularities, and noisy social-media style expressions are handled at this stage. The goal is to reduce superficial noise while preserving semantic content before the data reaches the model. It has a direct impact on performance, especially in heterogeneous sources such as enterprise text, user feedback, OCR output, and conversational data.</p>
