Why I'm Building These
I’ve always found myself needing tiny tools to speed up repetitive tasks — things like:
Cleaning URLs before sharing
Converting CSV to Parquet for ETL jobs
Mocking test data for demos or clients
So I started building CSVTools Online to:
Solve daily dev/data annoyances
Keep everything free, fast, and browser-based
Avoid login/signup hell 🔥

What’s Coming Next?
I'm planning to roll out:
Excel Formula Explainers
Image metadata scrapers
More developer-focused converters
