the second chainring on my crank is starting to wear out and skip so i’m looking at having to replace the chainring. While i’m at it is it worth making the conversion to 1x? Rear setup is a shimano deore 10 speed 11-32 tooth that i could bump up to 34 if necessary but i’m still not sure that that’s enough for climbs.

I like compact double or, for touring, triple crankset. Anything can become 1x or 2x. Could be fun to try. A larger range cassette is usually needed for 1x, so changing your rear derailleur would also be needed
I’d take a hard look at the Deore M6100 drivetrain. If your BB and cranks are still okay, you could get a shifter, derailleur, cassette, chain, shift cable, housing, and a narrow-wide chainring for about $260 at Jenson and have a new, modern, wide-range 1x drivetrain.
I’ve done this on a few city bikes. You can then lose the front derailleur, the cable and the extra chainrings.
Replacing chainrings is easy and should not cost that much, replacing the whole crankset and most likely BB might not be worth it for the very limited gear range it will give you.
Ideally you’d want at least an 11-42 cassette to run a 1x. What’s your budget for the project? If you do go 1x, make sure to get a proper ‘narrow-wide’ chainring up front for proper chain retention. There’s some relatively cheap new Shimano Cues setups for 1×9 and 1×10. These run link-glide though so you’d have to change everything but worth looking at depending on your budget.
Replacing the Chainring would be easiest. look for the BCD stamped on the ring, or measure bolt distance.
If you want an easy way to try 1x, since you’ll have the crankarm off, you could unbolt the granny and big ring when you replace the middle ring and ride it around to see if the gearing works for you. Don’t remove the front derailleur until you’re sure, it can be a pain getting a triple front dialed it.
BTW, you could also not buy a new middle and just move the big ring, this gearing us good for cruising around, but it sounds like you do a lot of climbing.
Converting to 1x but keeping the tiny ass 11-30 cassette is sorta pointless.
