Accelerating DD of financials during valuation

I've received multiple sets of financials for multiple years for various businesses to really dig into locaiton-specific performance and comps

I appreciate this may sound naive (!) but is there a way to collate large numbers of multi-year financials to calculate SDE without having to simply brute force manually myself?

What approaches have you taken to gathering financials to analyse and easily compare valuations?

Thanks in advance!
