Zovo Spreadsheet Checker
Check a spreadsheet for errors before you import it, send it or report from it
Validates CSV, TSV and Excel files or pasted tables. Muse can profile the columns, then flag duplicate rows and IDs, impossible or mixed-format dates, invalid emails, wrong phone lengths, blanks, numbers stored as text, stray spaces and totals that do not add up.
Try asking Muse: "Check customers.xlsx for duplicate emails and bad dates before I import it."
