Accurate Mixed-Data Entry Task

I have a collection of records containing both numbers and text that need to be transferred, checked for consistency, and neatly organized into a structured spreadsheet or database. The sources arrive in different formats—PDF exports, CSV files, and occasional handwritten scans—so I need someone comfortable switching between them while keeping everything aligned and error-free.

Here’s what matters most to me:
• Every value and word ends up in the correct column, spelled and formatted exactly as in the source.
• Obvious duplicates or mis-keyed entries are flagged so I can confirm before you finalize.
• Your final file is delivered in Excel or Google Sheets with clear, sortable headers.

If you regularly work with large mixed datasets and understand the importance of accuracy, I’d love to hear how quickly you could turn this around and what process you follow to keep error rates low.
