CSV Schema Guard

Compare a trusted CSV against a new file before it enters a workflow. Catch missing columns, type drift, null spikes, duplicate keys, row-count swings, and suspicious value shifts.

Local data quality gate Use this as a preflight check for recurring exports, vendor feeds, analytics drops, ops reports, or any CSV that can quietly change shape.

Trusted baseline

The known-good CSV shape you expect future files to follow.

Reconcile the file Move from schema preflight into duplicate checks, cleanup, lookups, and cycle count reports. Validate identifiers Check UPC, EAN, and Code 128 values before label or WMS import issues spread. Feed a slotting plan Use stable SKU, velocity, cube, and location fields before building pick-path moves. Review count variance Use stable cycle count exports to flag recounts, value impact, and inventory accuracy drivers.
