What usually goes wrong with it
Manual upload of individual files
Most tools require selecting and uploading each Excel file one by one, which is time-consuming when handling hundreds of reports.
DataMimi DataMimi lets you drop an entire folder, automatically reading all Excel files inside without manual uploads.
Inconsistent sheet names and structures
Excel files from different weeks or months often have varying sheet names or column orders, causing errors or misaligned merges.
DataMimi It scans sheet names and column structures to align data even when files differ in layout.
Hidden subtotal or total rows
Some reports include subtotal rows that should be excluded from the final merged file to avoid double counting.
DataMimi Subtotal and total rows are detected and excluded from the merged output to avoid inflated totals.
Mixed file formats within folder
Folders may contain both .xlsx and .xls files or CSV exports, complicating batch merging without format-specific handling.
DataMimi Files in .xlsx, .xls, and CSV formats are all supported in one batch merge.
Large volume causing slow processing
Merging hundreds of files manually or with basic tools often leads to slow performance or crashes.
DataMimi Optimized processing handles hundreds of files efficiently without freezing or crashing.
