The six checks
Exactly what gets cleaned
Each check is a separate rule — you tick the ones to run, and a cleaning report sheet lists every change made.
Control and non-printable characters that break imports are stripped from cell text.
Leading, trailing and doubled spaces are trimmed so lookups and filters match again.
Text-formatted numbers are standardised so sums and pivots include them.
Dates written in different styles are normalised to one consistent format.
Fully blank rows that break sorting and ranges are removed.
Exact duplicate rows are removed, and the report shows how many were dropped.
