I was in the same situation. I converted my paper logbooks into an excel spreadsheet by making one excel row for every page in my logbook. Then multiple columns for aircraft and type of time (PIC, IMC, etc). Discovered some logbook errors along the way. It was a PITA and took hours.
But at the end of the process, I was confident that I had represented my total time (and all the required subcategories) as accurately as possible. I got hired at AA and had zero logbook questions during the interview process. In other words, it was worth it to me.
And I still keep my paper logbook. Old school, yes, but it is a history of my flying life and I like it that way!
