Practical Text Cleaning Workflows
Clean an Email List Before Importing
Paste a contact export, use Extract Emails, then remove duplicates and sort A to Z. This gives you a clean one-email-per-line list that is easier to review before importing into a CRM, newsletter tool, or spreadsheet.
Prepare Spreadsheet Data
Use Trim Whitespace, Remove Empty Lines, and Remove Double Spaces to normalize copied spreadsheet columns. The live word, character, and line counters help confirm that rows were not accidentally lost.
Turn Titles Into Clean URL Slugs
Paste a page title, convert it to a URL slug, and copy the result for blog posts, product pages, documentation, or CMS entries. The output stays readable and removes punctuation that can break URLs.
Strip HTML From Scraped Text
Remove HTML tags from snippets copied from web pages, CMS exports, or template files. Follow with whitespace cleanup to create plain text that is easier to read, search, translate, or analyze.
