I review business spreadsheets for inconsistent formatting, broken or suspicious formulas, missing ranges, duplicated logic, and totals that do not reconcile. The service begins with a bounded intake and a preserved copy of the original workbook. Deliverables can include a cleaned workbook, a source-linked issue log, corrected formulas within the agreed scope, and a concise explanation of material changes. I distinguish visual cleanup from calculation-risk review, do not invent missing business rules, and identify items that require the owner’s decision. Projects use clear limits for workbook size, formula issues, revisions, and deadline before work begins.
