Terms of service
Effective 2026-10-02. By using Zovo Spreadsheet Checker you agree to these terms.
The service
Zovo Spreadsheet Checker is a tool provided by Zovo, a brand operated by autom8 LLC for use inside ChatGPT, Claude, and other MCP clients. Zovo Spreadsheet Checker reads a CSV or Excel file and finds the data errors that break imports and reports, such as dates that do not exist (February 30, month 13, February 29 in a non-leap year), dates written in a different order or format than the rest of the column, invalid email addresses and likely domain typos, phone numbers with the wrong number of digits, duplicate IDs and duplicate rows, blank cells in columns that should be filled, text and placeholders in number columns, numbers stored as text, mixed decimal marks, leading and trailing spaces, IDs and ZIP codes that lost their leading zeros or turned into 1.2E+15, formula errors, and row totals that do not add up. Column types are detected from the values and headings, and you can add your own rules: required columns, unique columns, allowed values, numeric ranges and total formulas. You get an issue list with row, column and the cell value, counts per check, an Excel copy with problem cells highlighted plus an Issues sheet, and a CSV of the issues. For Excel files the copy is your own workbook with flagged cells filled, so formulas and formats stay as they were.
