What usually goes wrong with it
Columns with different names but same data
Data from different sheets often use different column headers like 'Qty' vs 'Quantity' or 'Sales Rep' vs 'Salesperson', making manual merges error-prone.
DataMimi Automatically matches similar columns with different names to align data correctly
Duplicate rows during merge
When merging multiple exports, identical transactions or customers can appear multiple times, inflating totals if not removed.
DataMimi Detects and removes duplicate rows to prevent inflated totals
Inconsistent data types across sheets
Dates or numbers stored as text in one sheet but as proper formats in another cause errors in calculations after merging.
DataMimi Converts inconsistent data types like text dates into proper formats during merging
Subtotal or header rows breaking merges
Sheets sometimes include subtotal rows or repeated header rows that interfere with clean concatenation and analysis.
DataMimi Ignores subtotal and repeated header rows that disrupt clean merges
Manual reformatting slows report delivery
Manually aligning columns, removing duplicates, and fixing data types before analysis delays report completion.
DataMimi Previews the merged dataset before export to verify accuracy

Try it with your own file
DataMimi reads the file you actually have — merged cells, headers below row one, totals pasted at the bottom — and shows which rows and columns every number came from.
