What is csv-api?
csv-api turns any CSV file into a live REST API in seconds. Upload a spreadsheet, and you instantly get a queryable endpoint with filtering, sorting, pagination, and type detection — no backend code, no deploy step, no configuration. It's built for developers who need data endpoints fast: prototypes, internal tools, static sites, or quick data sharing.
Dog-fooding: we use our own product
The landing page you see at csv-api.com is itself powered by csv-api datasets. Two sections on the front page pull their content straight from the database using the same dynamic tables that back every user's API:
-
"Everything you need"
The feature cards (Filtering & Sorting, Pagination, Type Detection, etc.) are stored in a CSV dataset and loaded from a dynamic table at render time.
-
"Built for your workflow"
The use-case cards (Rapid Prototyping, Internal Tools, Static Sites & SPAs, Data Sharing) come from a second CSV dataset, queried the same way.
The data was imported with a migration that parses the CSV files, creates datasets, and builds the dynamic tables — the exact same pipeline every user's upload goes through. If the datasets aren't available, the page gracefully falls back to hardcoded defaults. It's a small thing, but it means the landing page is a live proof that the product works.
