CSV Trim & Data Sanitization Utility
Data quality often suffers from "invisible" issues like leading whitespace or hidden control characters. Our **CSV Trim & Sanitize** tool provides a one-click solution to deep-clean your datasets.
Cleaning Operations
- Trim Whitespace: Removes leading and trailing spaces from every cell in your CSV.
- Remove Hidden Characters: Strips non-printable ASCII and control characters (e.g., Null, ESC, Bell).
- Case Standardization: Optionally convert all text to UPPERCASE, lowercase, or Title Case.
- Empty Field Cleanup: Replaces whitespace-only fields with true empty strings or nulls.
Why Clean Your CSV?
Hidden spaces are a common cause of "failed matches" in SQL joins and lookups."John Doe " is not the same as "John Doe". By sanitizing your CSV, you eliminate these subtle bugs and ensure your data is ready for analysis or migration.
Frequently Asked Questions
What does 'Sanitize' actually do?

Can I trim specific columns only?
The current version applies trimming and sanitization to all columns to ensure global data consistency, which is the most common requirement for data cleaning.
