Next: Select the Invisible Character Remover Tool

Finally: Export Your Results

When you're satisfied with the results, simply click the "Export" button. Your transformed data will be downloaded as a new CSV file, ready to use in Excel, Google Sheets, databases, or any other tool you prefer.

Export formats:

  • CSV: The most widely supported format, compatible with virtually all data tools and programming languages.
  • Excel (XLSX): A native Excel format that preserves formatting, formulas, and data types for seamless integration with Microsoft Excel.
  • JSON: Ideal for web developers and API integrations, providing a structured format that is easy to work with in JavaScript and other programming languages.
  • TSV: A tab-separated format that is preferred by some systems and can be easily imported into various tools.
  • DSS: A custom format that represents sparse grids and sheets efficiently in plain text: no more binary files that can't be previewed or edited in a text editor. DSS files are perfect for sharing complex data structures while maintaining readability and editability.

When you export your results, the tool ensures that all encoding is preserved correctly. This means that any international characters, special symbols, or formatting in your data will remain intact, eliminating the common issue of garbled text or broken formulas that can occur with other tools. You can trust that your exported file will be clean and ready to use without any additional fixes needed.

More about Invisible Character Remover

Ghost Scrub scans your file for characters that render as blank but aren't, zero-width spaces (U+200B), non-breaking spaces (U+00A0), and other invisible Unicode marks that often sneak in from copy-pasted web content or exports from certain CMS and PDF tools. These characters look identical to a normal space in a spreadsheet but break exact-match filters, VLOOKUPs, regex, and API calls downstream. The tool strips them out while leaving your visible text untouched.

Frequently Asked Questions

What are "ghost" characters?

Invisible characters like zero-width spaces and non-breaking spaces that look like normal whitespace but break string comparisons, regex matches, and code that parses your CSV.

How would I know my file has this problem?

A classic symptom is a value that looks identical to another in a spreadsheet but fails an exact-match filter or lookup, that's usually a hidden character.

Common Use Cases

  • Fixing lookup failures where two values look identical but a VLOOKUP or JOIN won't match them
  • Cleaning text copy-pasted from web pages or PDFs before importing into a database
  • Sanitizing form-submitted data before it's used as a matching key in another system
