Repeatability
High
The transformation rules are explicit and consistent: E.164 phone formatting, lowercase emails, title-case job titles, deduplication, and flag missing fields. This is structurally identical every time the file is processed.
Ambiguity Tolerance
High
Success criteria are well-defined — specific output format, a named flag column, and clear normalization targets. The only ambiguity is in job title standardization, where abbreviations may require judgment, but this is a small fraction of the work.
Data & Tool Availability
High
The input is a single Excel file the user can upload directly. Standard libraries (pandas, phonenumbers, etc.) or a code-capable agent can handle all transformations without external APIs or special permissions.
Error Cost
Low
The output is a new CSV, leaving the original file intact and fully reversible. Errors in normalization are visible and auditable before the cleaned file is used in production.
Human Judgment Required
Low
Phone and email standardization are purely mechanical. Job title normalization is the one area where human review of edge cases is useful, but the agent can flag uncertain rows rather than silently guess.
