Excel Mixed-Data Consolidation

I have a collection of CSV and native Excel files that need to be merged into one clean, well-structured workbook. The source material already sits in digital form, so no manual transcription from scans is required—just careful extraction and organization of the mixed data (both numbers and text).

Here’s what I need from you:

• Import each CSV/Excel source, preserving every value exactly as it appears.
• Standardize column headers and align the datasets into a single master sheet (or a set of logically separated tabs if that proves clearer).
• Run quick checks—basic formulas, filters, or conditional formatting—so obvious discrepancies or mis-typed entries surface immediately.
• Deliver the final .xlsx file plus a brief note summarizing any issues you spotted and how you resolved them.

Accuracy matters more than speed, but if you can finish promptly without sacrificing precision that’s ideal. Let me know your experience with large-scale Excel data handling and when you can start.
