Validating Data Extracted from Files

[Ari King]

Hi,

I'm sourcing data from multiple excel files (workbooks) each with multiple worksheets. Prior to persisting the aggregated data, I want to validate it. I was thinking of creating classes to hold the data and validate type and content via methods. I'd appreciate feedback on this approach, suggestions on possibly better alternatives, and if there are existing libraries that provide this functionality. Thanks.

Best,
Ari
