Choose the tool that matches your cleanup task

• For line changes, use Merge Lines, Remove Duplicate Lines, Remove Empty Lines, Remove Lines Containing Specific Words, or Trim Lines to Max Length.
• For words, spaces, and characters, use Remove Duplicate Words, Remove Stop Words, Remove Accents / Diacritics, Remove BOM (Byte Order Mark), Remove Non-Printable Characters, Remove HTML Tags, Remove Special Characters, Remove Punctuation, or Trim Whitespace.
• For detected patterns, use Remove Email Addresses, Remove URLs From Text, or Remove Numbers from Text.
• Use Text Cleaner when you need several cleanup actions in one run.

Use the available cleanup controls

• Remove Lines Containing Specific Words removes the entire line when it matches. Set Use regex, Case sensitive, and Trim spaces before checking carefully.
• Remove Duplicate Lines has Case sensitive and Trim spaces before comparing. Remove Duplicate Words has Case sensitive and Trim spaces between words.
• Trim Lines to Max Length accepts 1 to 50 in its length field. Enable Add … when trimmed if shortened lines should show an ellipsis.
• In Remove Punctuation, choose Preserve apostrophes, Preserve hyphens & dashes, Preserve decimal points, and Also keep as needed. Choose Remove or Replace with space, then decide whether to Clean up leftover whitespace.
• In Remove Special Characters, choose Keep spaces, Keep newlines, Keep numbers, and Also keep these characters. Remove Non-Printable Characters separately provides Keep tabs and Keep newlines.
• Remove URLs From Text can enable Match bare domain-style URLs (no scheme or www). Remove Numbers from Text lets you choose digit characters or whole number tokens, a number format, and removal or replacement. Remove HTML Tags includes Decode HTML entities.

Use Text Cleaner for a combined cleanup

Choose General Text, Documents, Email, AI / Markdown, Code, or Data to load a starting set of actions. You can then change the action checkboxes.

Set Tab size from 1 to 12 and Max blank lines from 0 to 10. Enabled actions run in a fixed pipeline order. The Code preset avoids per-line leading-whitespace trimming and space collapsing, but it trims whitespace at the whole-file boundaries and converts tabs to spaces.

Review, copy, or download the result

Check the generated output before using it. The inspected tools do not use a general Process button; several update through JavaScript as you type or change options. Select Copy to place the result on the clipboard, or Download to save it when shown.

Limitations and local processing

The inspected transformations read files with FileReader, create downloads with Blob, and use browser JavaScript for text changes and clipboard copying. No network request was found in those text-transformation scripts. Browser compatibility and offline behavior are not documented.

No category-wide input-size, file-size, character-set, or line-count limits are documented. Review results especially after using regex, replacement, or multiple Text Cleaner actions.
