Text Cleaner
Clean up messy, inconsistently formatted text with a suite of configurable processing toggles — remove duplicate spaces, trim leading and trailing whitespace from each line, delete empty lines, remove duplicate lines, normalize mixed line endings (CRLF/LF), and strip special characters. This tool is invaluable for cleaning data copied from PDF documents (which often introduces random line breaks and double spaces), sanitizing text pasted from web pages, preparing CSV and log file data for analysis, and normalizing imported content before publishing. Each cleaning operation runs independently and can be combined in any configuration, with a real-time preview of the cleaned output alongside your original text. Processing runs entirely client-side, ensuring that sensitive business data, legal documents, and personal information never leave your device.

Deterministic Whitespace Normalization & Regex Sanitization
Mathematical derivation, technical breakdown & worked practical example
Text cleaning sanitizes raw unstructured text by stripping extraneous formatting artifacts. It normalizes mixed line endings (CRLF to LF), collapses consecutive whitespace spaces into single spaces, removes non-printable ASCII control characters, and deduplicates identical lines while maintaining structural readability.
Worked Example: Cleaning Messy Data Copied from a PDF Table
Sanitizing text copied from a PDF with jagged line breaks and double spaces.
- Strip trailing and leading spaces from every line using regex /^\s+|\s+$/gm
- Collapse multi-spaces: replace /\s{2,}/g with single space " "
- Remove empty lines: filter out empty string elements
- Configurable toggle switches allow you to choose exactly which cleanup rules to apply.
- Saves hours of manual backspace and delete editing on large text documents.
How to use Text Cleaner
- 1 Paste your raw text into the input box.
- 2 Toggle desired cleaning rules using the control switches.
- 3 Click "Clean Text".
- 4 Copy the sanitized text.
