How it Works

Text Cleaner analyzes and reconstructs your input text using efficient string manipulation algorithms and Regular Expressions (RegEx), all in your browser.

1. Processing Pipeline

Your text goes through a series of cleaning steps: removing empty lines, eliminating duplicates, and trimming whitespace. Each step builds on the previous one.

2. Smart Extraction

In extraction mode, the tool scans the text using precise RegEx patterns to identify emails or URLs, collecting them into a clean, unique list.

3. Local Privacy

All processing happens in your browser's memory (RAM). Your data is never sent to any external server, ensuring complete privacy.

Use Cases

Frequently Asked Questions

Is "Unique Lines" case sensitive?

Yes. The algorithm distinguishes between cases. "Apple" and "apple" are considered two different lines and will both be preserved.

How accurate is email extraction?

We use standard regex patterns that catch almost all correctly formatted emails (name@domain.com). Emails deliberately obfuscated to avoid scraping (like name [at] domain) may not be detected.

Does it lag with large files?

Processing thousands of lines is instantaneous. However, pasting huge text blocks (tens of megabytes) might cause a momentary freeze due to browser memory limits.

Are all empty lines removed?

Yes. With "Remove Empty" on, lines that are completely empty or contain only whitespace (tabs, spaces) will be removed.

Which URL protocols are supported?

Common protocols like HTTP, HTTPS, and FTP are supported. Strings starting with these protocols are typically extracted correctly.

Is my data uploaded?

Never. This is a Client-side application. No data is sent to any server; everything stays in your browser tab.

Can I split lines by separator?

This version focuses on line-based operations. For complex splitting or replacing, we recommend using a Regex editor or advanced text editor.

How can I undo?

Direct undo isn't supported, but your original Input Text is always preserved on the left (or top). Processing only affects the Output box, so your source data is safe.
