Python Script to Parse CSV, Identify Duplicates, and Generate Cleaned Dataset with Summary Report
“Create a Python script that parses CSV files, identifies duplicate entries, and generates a cleaned dataset with a summary report”
Summary · Write a Python script to parse CSV files, detect duplicate rows, output a cleaned deduplicated dataset, and produce a summary report of what was removed and why.
CSV parsing and duplicate detection are well-defined, code-centric tasks with no sensitive judgment, physical action, or deep proprietary context required. AI produces correct, idiomatic Python for this class of problem reliably, and the output is easy to verify by running the script against sample data. Light human review is sufficient.
Where AI helps most
Generating the boilerplate script, handling pandas deduplication logic, and formatting the summary report — tasks that take an expert 30–60 minutes — are done in under 2 minutes by AI, with the remainder being testing and business-rule clarification.

Worker comparison
six profiles| Worker | Time | Cost | What you actually get | Conf. |
|---|---|---|---|---|
|
01
Solo Individual
DIY on your own time, no contract, no schedule
|
3–8 hours | $0 (personal time) or $20–$60 if hiring on a per-task basis | A first-timer will likely produce a working script for simple cases but may miss edge cases: encoding issues, mixed data types, case-sensitive vs case-insensitive duplicates, or partial duplicates on a subset of columns. Stack Overflow and ChatGPT can fill gaps, but debugging unfamiliar pandas or csv-module behavior adds significant time. The script is unlikely to be production-hardened or well-documented without extra effort. | medium |
|
02
Solo Expert
Hire a freelance specialist, day rate, scoped per job
|
30–90 minutes | $75–$200 as a flat freelance engagement | A Python-proficient developer will reach for pandas quickly, handle encoding and dtype edge cases, parameterize column selection for duplicate detection, and produce readable output. Freelance engagement friction is real: vetting on Upwork or Toptal takes time, scope creep around 'what counts as a duplicate' is common, and a one-off script rarely comes with a support commitment. Revisions may be limited or billable separately. Turnaround on a marketplace can be days even for short work. | high |
|
03
Small Team
Coordinate 2 or 3 freelancers, handoffs and gaps
|
1–3 hours (wall-clock 1–2 days with coordination) | $150–$400 blended | A mixed team adds code review, which genuinely improves robustness, but introduces coordination overhead — agreeing on output format, who writes the report template, and who tests. For a script this size, team overhead can exceed the coding time. Best suited when the task is part of a larger data pipeline project, not a one-off. Calendar time stretches to a day or two even when billable hours are low. | medium |
|
04
Agency
Account-managed, billable hours, formal scope and SOW
|
4–8 hours billable (1–2 week calendar turnaround) | $500–$1,500 depending on scope and agency tier | An agency will scope, estimate, build, review, and deliver with documentation — overkill for a self-contained utility script unless it fits into a larger engagement. Expect a discovery call, a statement of work, and multiple approval checkpoints. Agencies rarely take on small standalone scripts; minimum engagement fees can make this cost-prohibitive. Quality is high, but the calendar wait and process overhead are substantial. | medium |
|
05
Enterprise
RFP, procurement, multi-stakeholder approvals
|
1–3 weeks (wall-clock) with a few hours of actual coding | $1,000–$5,000+ internal loaded cost including overhead | Enterprise processes add ticket creation, sprint planning, security review, code review, QA, and deployment approval. A simple data-cleaning script becomes a formal deliverable requiring documentation, version control standards, and sign-off. Actual coding is a small fraction of elapsed time. Internal loaded cost (salary, benefits, overhead) makes even trivial scripts expensive in accounting terms. Suitable only when the script feeds a governed data pipeline. | low |
|
AI
AI (Claude / Agent)
AI plus competent human review
|
10–25 minutes including human review and testing | $0–$5 in API costs; ~$0 with a subscription tool like Claude or Copilot | AI generates a solid working script very quickly — pandas-based deduplication, configurable column subsets, CSV output, and a text or HTML summary report are all well within current capability. Human reviewer needs to: verify duplicate-detection logic matches actual business rules (exact vs. fuzzy, which columns), test against a real sample file with encoding edge cases, and confirm the summary report format meets downstream needs. Main failure modes: silently wrong logic when 'duplicate' is ambiguous in the prompt, no error handling for malformed input, and brittle assumptions about column names. Plan 10–15 minutes of real testing against your actual data. | high |
