Today in ridiculously specific tools... if you ever have data that's been gzipped and then base64-encoded and you need to see what's in it, my new "base64 decode and then un-gzip" tool is for you! observablehq.com/@simonw/base6

Built because I'm using pytest-recording and it turns out it sometimes stores base64-gzipped responses in YAML files github.com/datasette/datasette

Screenshot of an Observable notebook - base64 decode and then un-gzip A big bob of base64 has been pasted in a textarea Below it some decoded JSON is displayed - it's a nested object with an emedding vector of floats

@simon Sorry to be another reply guy, but I find CyberChef very useful for this kind of quick and dirty conversion. It's a handy downloadable single HTML file from our friends at GCHQ

Edit: Direct link to this recipe: tinyurl.com/mw45spm3
