## The problem

Repeated spreadsheet cleanup wastes time and creates manual errors.

## The prompt

> Build an upload tool that accepts messy CSVs, dedupes rows, normalizes columns, previews changes, and exports a clean CSV.

## What you get

- Private upload page
- Column mapping flow
- Dedupe and normalization logic
- Clean CSV export

## What to have ready

- Example messy CSV
- Rules for duplicate rows and column names
- Desired output format

## Limits

- Large files may need chunked processing or a database-backed workflow.
- Ambiguous cleanup rules should be reviewed before bulk use.

## Done when

- A sample file uploads successfully.
- Previewed transformations match the cleanup rules.
- The exported CSV is usable by the destination system.

## Cost

Estimate: Low for small files; medium for large files or complex validation.
