Normalization
Convert field values to canonical forms, so the same thing is written the same way everywhere.
One city, five spellings. Dallas, DALLAS, Dallas TX, dallas and Dallas, Texas are five values for one city. Every filter that names one of them misses the other four, and every report built on those filters is quietly wrong.
Normalization is the least glamorous tool and the one everything else depends on. Matching cannot find duplicates across five spellings. Segments cannot select on a field that holds five values for one thing. A score weighted on industry is weighted on noise.
A scheme is a set of field rules. Each rule names a field and the canonical form it should take: title case for cities, the bare domain for websites, E.164 for phone numbers, the two-letter code for countries. The rules are saved on the connection, so the same scheme runs next quarter without being rewritten.
Preview before you write. A scheme can be previewed against your real records, so you see what it would change and how many records it touches before anything is written.
How a pass runs
The detail
Changed only
A normalization pass over a clean book should write zero records.
Most tools that touch every record in a scope write to every record in that scope. This one diffs first: it computes the canonical value, compares it to what the record holds, and skips the ones that already agree.
That is what makes normalization safe to run on a schedule. The second pass over the same scope is a no-op, your CRM's modified timestamps do not churn, and the audit trail records the handful of records that actually moved rather than ten thousand that did not.
For agents
Reads are free and need no permission to write. Anything that changes a record is a separate grant.
