Applying Data Validation Business Rules

I am in charge of validating 800+ excel reports coming from our vendors each month. I use excel data validation feature everytime I receive a new file. Data Validation feature is native to the excel workbook and cannot be saved to be used with other workbooks (at least; this is what I think).

What is the best way to write a generic validation script that I can run on any workbook. I am thinking somewhere along the lines of a test script that looks for specific data, data format, required data etc.

Here are some of the rules I have to validate against:

Cells in Column 'A' must contain data, reject if not populated.Cells in Column 'B' must contain a specific value (cat, dog, car), reject if other.Cells in Coulmn 'C' must contain (CA,AMM) only if cells in Column 'D' = 'Yes'Cells in Coulmn 'E' must be in proper casingAddress must use U.S. Postal Service standardsZip Code must be 5digits+4Exclude formatting charecters like '( )' from phone numberMinumum age must be less than or equal max ageMaximum age must be greater than Min ageCheck for populated data in cells, else reject file.Date must be in 'YYYMMDD' formatTime must be in HH:MM:SS' or 'MM:SS' formatID must contain 7 integersThis is a sample that represent 70% of files recived.
