There are many times I find some government data in shapefile (.shp) format but want to use the attributes inside for analysis in tabular format. It's always a pain to open this in QGIS, convert the CRS correctly, then save as CSV. So I built a tool that will handle this for you, all running within the browser so data doesn't need to be sent anywhere. Under the hood it's using DuckDB built for Wasm + the spatial extension (which links GEOS). And full disclaimer, I'm using this as lead generation for my Honeycomb Maps product, but if you'd prefer not to give your email that's completely fine, just put from@hn.com or something similar :)
