Excel Numeric Data Entry

I have several source spreadsheet files filled entirely with numbers that must be transferred into a single master Microsoft Excel workbook. Your task is to copy each numeric value into the correct column and row, keep the existing formats intact, and double-check totals so the data stays reliable for later calculations.

I will supply the source spreadsheets and a template of the master file. Once you finish, return the updated workbook along with a brief note of any inconsistencies or issues you uncover during entry. Accuracy and careful attention to cell placement are all that matter here; no text entry or complex formulas are involved—just precise numeric data copying within Excel.
