Smart Date Normalizer: Zero bloat, client-side date format normalization.

An automatic date format normalizer that handles messy, mixed-up datasets without breaking your raw text. Coded in pure browser JavaScript and HTML to run locally. Part of the Summit Side Utilities minimalistic utility suite.

Good Morning Product Hunt! I spent a bunch of time researching things that actually annoy data analysts and developers during their daily workflows. One of the biggest complaints I found was how frustrating it is to fix a messy, mixed-up variety of date formats in data files using modern bloated web tools, so I built a tool to make it fast and simple. This was coded in pure browser JavaScript and html so it runs locally on your machine—your data never touches a server, and you don't have to create a useless account just to fix a few lines of text. Access to this tool—and any new micro-utilities I build in the future—is a straight $2/month subscription. You get a single text key to unlock the page instantly. It is the first tool of a minimalist utility suite I am building. Let me know what you think.

Honestly this looks handy for cleaning up spreadsheets, but it would be really useful if you could add a bulk preview mode that shows the before and after for a whole column at once before you commit to the changes. Right now I assume you have to run it blindly and hope for the best, which kind of defeats the point when dealing with messy data.

@erhanporl Thanks Erhan. That's a good point actually, and I will incorporate it into my utilities. I had thought about it before but wasn't sure if it was an actual problem for users. Thanks for letting me know!

Finally something that doesn't choke on the weird date formats in my scraped data. Loved that it all runs locally without uploading anything sketchy.
