What DataMimi is built to do
- Answers you can audit. Every answer shows the sheet, the columns it used, any filters and how many rows the figures were computed over.
- Messy exports as they arrive. Headers below row one, merged cells and totals rows are handled, and every change is reported before a number is quoted.
- Cleaning you approve. Duplicates, numbers stored as text and spelling variants are shown with before-and-after examples; the original file is never overwritten.
- What to look at first. When a file is read, the largest changes, outliers and gaps in the data are pointed out without spending credits.
- Deliverables. Charts, slide decks, written reports and cleaned Excel exports from the same analysis.
