Show HN: A fast way to clean and convert messy CSV/JSON files in the browser
datumintapp.com
I often work with CSV and JSON files that are a bit messy - duplicates, inconsistent formatting, or just hard to inspect.
I usually end up jumping between Excel, scripts, and random online tools.
So I started building a small browser-based tool to make this easier.
Right now it lets you:
- Convert between JSON, CSV, Excel formats
- Remove duplicates quickly
- Filter and reshape data visually
- Inspect basic issues in the file
and few more.
Everything runs in the browser - no uploads to a server.
It’s still early, but I’d love to know your experience and thoughts about the product.
Maybe I am missing something or thinking wrong, your response will really matter. So looking forward for your feedback.
I would like to ask:
- what is that thing in your data workflows or data tasks, that feels like slowing you or like giving a sharp pain regularly?
