Edit Numeric Excel Data

I have several workbooks filled with numeric information that now needs a careful refresh. All of the incoming numbers are already sitting in companion CSV or Excel files, so the task is strictly digital—no scanning or transcription from paper.

Here is what I need done:

• Open my current spreadsheets, locate the rows and columns flagged in comments, and correct any inaccurate figures.
• Import new numeric records from the supplied CSV / Excel files, making sure the data lines up perfectly with the existing column structure.
• Preserve every existing formula, reference, and formatting rule so that nothing breaks after the update.
• Spot-check totals and subtotals to confirm the edits balance out.

When you return the files, I will verify results by running a few test calculations; clean reconciliation on the first pass will be the main acceptance criterion. If you have solid experience with data validation, VLOOKUP / XLOOKUP, and quick turnaround times, this should be a straightforward assignment.
