## Frequently asked questions

### When should I normalize before editing columns?

Normalize first when you are unsure about delimiter, encoding, header placement, or damaged rows; otherwise later steps may clean the wrong structure.

### Should I merge files before filtering them?

Usually no. Clean each extract enough to confirm compatible headers, then merge into a controlled master file.

### When is transposition useful for CSV?

Use it when fields were exported as rows instead of columns, or when a review process needs side-by-side comparison of a narrow record set.

### Why compare against Excel if the final output is CSV?

Many handoffs are reviewed in spreadsheets first. A diff step catches header drift, row loss, and value changes before import.
