Excel Data Cleanup & Formulas -- 2

I have several spreadsheets that now feel unwieldy and inconsistent. I need someone who can step in, quickly understand the structure, and turn them into clean, reliable workbooks.

Here’s what I specifically need:
• Data entry of new records without introducing errors
• Applying the right filters so the information I need surfaces instantly
• Building or correcting formulas to automate totals, look-ups, and other basic calculations

You’re welcome to suggest smarter ways to structure the sheets if it will speed up future updates. If things go smoothly, I may also pass along some light photo edits and ID-card layout tweaks later, but the first milestone is all about getting these Excel files running efficiently.

The deliverable is a polished workbook (or set of workbooks) that opens without warnings, returns accurate results, and is easy for me to maintain going forward.
