Prompt template
I have a very messy spreadsheet and want to tidy it into a clean, analyzable format. From a data analyst's view, tell me step by step how to clean it. Roughly what the data looks like: (describe the columns, e.g., date/product/quantity/amount, or paste the first few rows) The question I ultimately want this data to answer: (e.g., which month sold best, which product had the most returns) Problems I've found so far: (e.g., inconsistent date formats, blank rows, inconsistent category names) Please: 1. List the items needing cleaning (as a list, ordered by what to handle first) 2. Give a concrete handling method for each (manual or with a tool) 3. After cleaning, suggest 2-3 angles to slice the data to answer my question 4. Remind me of common data traps to watch for (e.g., double counting, inconsistent units)
