How to Convert Case and Clean Text Quickly
Fix uppercase, lowercase, title case, duplicate lines, and messy spacing without uploading text.
Pick the final format first
Use uppercase or lowercase for simple cleanup. Use sentence case for paragraphs, title case for headings, and camelCase, snake_case, or kebab-case for code-like names and labels.
Clean pasted lists in small steps
When text comes from a spreadsheet, CMS, PDF, or email, run cleanup actions one at a time. Trim lines, remove empty rows, remove duplicate lines, then sort only if alphabetical order helps.
- Duplicate-line removal keeps the first exact match.
- Normalize spaces when copied text has repeated spaces or tabs.
- Swap output back into input when you want another pass.
Check meaning before publishing
Case conversion is mechanical. Names, acronyms, brand capitalization, and editorial style rules may still need a quick manual pass before the text goes live.
