Sound familiar?
Court filing systems reject CSVs with inconsistent date formats (MM/DD vs DD/MM)
Case management imports fail because birthdates are formatted differently than filing dates
You waste hours manually reformatting dates in Excel before every system import
Why Paralegals choose browser-based cleaning
Your firm exports 500 case records for a new e-discovery platform. The export has birthdates in MM/DD/YYYY, filing dates in YYYY-MM-DD, and court dates in "January 5, 2024" format. The platform rejects the import. With cloud tools, you'd upload client SSNs and case details to a third party. With CSVCleaner, you fix all dates to ISO format in seconds — entirely in your browser.
