Download CSV Test Pack

A comprehensive CSV testing toolkit. Includes clean CSV files in multiple sizes, realistic datasets (users, products, sales), and intentionally broken files with common CSV problems — UTF-8 BOM, inconsistent columns, unescaped quotes, and mixed delimiters. Everything you need to test CSV parsers, import pipelines, and data validation logic.

Why This Bundle?

CSV is deceptively simple — the lack of a strict standard means real-world CSV files are full of edge cases. This pack covers both ideal and broken scenarios so you can ensure your parser handles everything from clean exports to messy legacy data.

Frequently Asked Questions

What CSV problems are in the broken files?

UTF-8 BOM prefix, inconsistent column counts, unescaped quotes, mixed delimiters (comma and semicolon), and fields with raw newlines.

Are the datasets realistic?

Yes. The user and sales datasets contain realistic field names, data types, and distributions matching real-world CRM and analytics data.
