HelloCSV - A free FlatFile alternative

Maker

📌

Hello ProductHunt! TLDR: HelloCSV is an open source, free, Flatfile alternative We're a software shop and almost every project we work on inevitably needs a CSV importer, which all share the same set of problems: - How do you make sure that data uploaded is correct - How do you notify the user that the data is incorrect before they upload it, and give the user a chance to fix it - Incorrect or duplicate data that is uploaded is super annoying to try to fix after-the-fact - Run automatic formatters (ex: phone number formatting), but providing a way for the user to see what our formatter did before uploading as a sanity check So we built a tool that we've been using internally for a few months now, and just polished it up and open sourced it. It's basically a drop in CSV importer that: - Supports custom columns - with custom validations - and custom transformations - and a nice UI that walks a user through a 4 step process of uploading a CSV (upload, map columns, preview data, upload confirmation) Some of the things we really tried to achieve for was: - Be able to use this for non-React / SPA projects - Keep bundle size small (99kb was as small as I was able to make it, really tried hard!) - 100% frontend, unlike alternatives like FlatFile / OneSchema that send data to remote servers. - 100% free & open source - The stack is as minimal & stable as we could make it. Preact for a tiny, stable reactive renderer + TanStack datatables for the preview. Demo: https://hellocsv.github.io/Hello... Code: https://github.com/HelloCSV/Hell...

@chris_zhu Super cool! Any plans to add bulk edit or “smart suggestions” during the mapping step?

@masump 👋 Thats a great idea! We have hooks to integrate with an LLM backend, but at the moment, nothing will be applied by default so developers would have to implement that themselves. We can explore it as we integrate deeper into our own product!

The next thing on the roadmap is supporting Excel files better and also supporting a localstorage extension so that users don't lose anything even if they refresh the page

We are planning to add more features and make this even more powerful than it is.
