What usually goes wrong with it
Hidden differences in merged cells
Merged cells may cause misalignment between versions, making it hard to detect changes in the underlying data.
DataMimi DataMimi aligns merged cells and detects underlying data differences despite misalignment.
Numbers stored as text
Numeric values formatted as text in one file but as numbers in the other can appear as differences even if the values are equivalent.
DataMimi It normalizes numbers stored as text to prevent false difference flags.
Extra or missing rows and columns
Rows or columns added or removed shift data, causing false mismatches when comparing files without structural alignment.
DataMimi The software aligns rows and columns structurally to avoid mismatches caused by extra or missing rows.
Inconsistent header rows
Headers not always on the first row or differing between files complicate identifying which rows contain comparable data.
DataMimi It detects header rows even when not in the first row to correctly match data across versions.
Formatting changes flagged as data changes
Differences in cell formatting such as font or background color are often irrelevant but can clutter comparison results if not filtered out.
DataMimi DataMimi filters out formatting changes so only actual data differences appear in the results.
