Show HN: DonutData – Clean messy datasets with natural language prompts

2 Ukd_1209 2 5/2/2025, 4:52:09 PM donutdata.in ↗

I built DonutData to make cleaning and preprocessing datasets easier — without writing any code.

You upload a file (CSV, JSON, XML), type a prompt like:

"Remove extra spaces, drop rows with nulls, lowercase all text"

…and DonutData runs the relevant transformations automatically.

This is the first version — preview/iteration is coming soon. Feedback form pops up after use. I’d love your thoughts!

Works with structured formats (CSV, JSON, YAML, XML) 30+ preprocessing operations built in Free to use — only sign in to download the result

Try it out: https://donutdata.in/ Use our sample dataset: https://drive.google.com/file/d/11NOu1FSm4nyYT8QZjcltmaN0LGu...

Would love to hear feedback of any kind!

We're in the process of finalizing the full privacy policy and as this is the first version we are still working on it. For now, to clarify: we don’t store or use any of your uploaded data beyond the processing session. Everything runs serverlessly and is wiped immediately after. If you have any specific concerns, feel free to ask or DM — happy to clarify anything! Would really like you to use it and provide feedback
