Business & farm

Sorry not from Excel.   Doesn’t your spreadsheet have totals?   You only need to enter the totals for income and each expense category.   I would try using Quicken.  I have an older Quicken that I can’t import but I setup my expense categories to match the Schedule C line numbers.  Then I can just enter the totals from my Quicken report.   It doesn’t take long just to enter the totals.
