WHAT YOU GET
Everything is included. There is no paid tier.
Csvshape has no accounts, no sign-in, no data collection, and no subscription. Every feature listed on this page works for every user on every visit. The tool runs entirely in your browser — nothing is uploaded to any server.
The only limit is what your browser can hold in memory. Files larger than approximately 100 MB trigger a clear warning rather than failing silently. This is a browser limitation, not an artificial cap — and it applies to everyone equally.
