VIN spreadsheet validator

Client

VIN spreadsheet validator targets fleet analysts exporting a single column from Excel or Google Sheets. Paste below for per-row mod-11 results without uploading the workbook.

From Excel to validator

Select the VIN column, copy, paste into the tool. Each non-empty line runs mod-11 independently—ideal for pre-import QA on logistics CSVs.

Privacy: parsing runs only in your browser. This page does not query DMV, insurance, or manufacturer databases—only the published mod-11 rule for the ninth character.
?

After removing spaces and hyphens, the frame must be exactly 17 characters. Letters I, O, and Q are forbidden everywhere. Position 9 (index 8) is the check symbol: decimal 0–9 or X for remainder ten. Each symbol maps to a numeric value, is multiplied by a fixed weight for its position, products are summed, and sum mod 11 must equal the check symbol’s value (X → 10).

Result

Passes check digit — weighted sum mod 11 is 10; expected X.
