App Data
Problems
Help me clean up messy spreadsheet data. App + what the data is: {APP_DATA} The problems (duplicates, inconsistent text, blanks, formats): {PROBLEMS} Give me: 1. A step-by-step cleanup plan (in order). 2. The formulas/features to use for each (TRIM, dedupe, split, find-replace, etc.). 3. How to do it without breaking the original (work on a copy). 4. A quick check that it worked. Practical and safe. Don't assume I'm advanced.
