The honest read

This is a well-scoped data cleaning task with clear inputs, defined rules, and reversible outputs — exactly where AI agents excel. The main wrinkle is fuzzy vendor name matching, which requires a confidence threshold and a short human review pass for edge cases. Everything else — deduplication logic, flagging, CSV output — is fully automatable.

The five dimensions

Repeatability

High

The structure is identical across all 36 files: same columns, same logic, same output format. This is a textbook repeatable ETL task with no instance-by-instance variation in approach.

Ambiguity Tolerance

Medium

Most success criteria are crisp — deduplicate, standardize, flag >$5K cross-month duplicates. The fuzzy vendor matching introduces genuine ambiguity: 'Acme Corp' vs 'Acme Corporation' is easy, but edge cases like 'Smith Consulting' vs 'Smith & Associates Consulting' require a judgment call or a master list to anchor against.

Data & Tool Availability

High

The user has all 36 CSV files ready and the column schema is known. A code agent can read, process, and write CSVs without any external API access or permissions beyond file I/O.

Error Cost

Medium

Errors are reversible — the original files are untouched and the output is a new CSV. However, a missed duplicate or a wrong vendor merge could cause downstream accounting errors if the output is used for tax prep or audits without human review.

Human Judgment Required

Low

The deduplication and flagging rules are algorithmic. The only genuine judgment call is resolving ambiguous vendor name matches, which can be handled by surfacing a short review list rather than requiring human involvement throughout.

What an agent would need

Access to all 36 QuickBooks CSV export files with consistent column headers (date, vendor, account code, amount)
A master vendor name list to anchor standardization, or the ability to generate one from the data and surface it for human confirmation
A fuzzy string matching library (e.g., rapidfuzz) with a configurable similarity threshold for vendor name normalization
Clear deduplication rule definition: same vendor + same amount + different month = flagged duplicate, not auto-removed
A human review step for low-confidence vendor name matches before the final cleaned CSV is accepted as authoritative
