What this task is
Checking entered data for completeness, correct formats and internal consistency, such as ID number length, totals that add up and logical dates, then fixing errors.
How AI replaces it
From 2020, rule engines automatically checked formats and numeric logic, and large language models added the ability to catch semantic contradictions and suggest fixes. By around 2026 routine validation is largely system-driven.
What stays human
People define and maintain the validation rules, resolve the records the system flags as suspicious, and give final sign-off on corrections that have significant downstream impact.
