Text and file cleanup

C# Find-and-Replace across text or multiple files.

Paste content or drop in a handful of files, then run exact or regex-based replacements with instant previews for every file you processed.

  • Regex and plain-text modes
  • Case sensitivity toggle
  • Per-file match counts

Powered by a .NET 8 minimal API—no uploads are saved.

Bring your own pattern, preview updates, and download cleaned copies.

Provide text or a regex. Empty values are rejected to avoid accidental blank replacements.

Drop in .txt, .md, .json, .html, .rtf, .docx, or code files—contents are processed in memory only.
