Exporting BioBlitz data

Is there a way to wrangle the exported data from a BioBlitz project and create a classic species vs time/effort curve? Ideally I’d want one column of each unique species and a second column of the exact time each of those species was first sampled. Unsure if this is possible considering as stuff gets ID’ed the two columns would be dynamic, but obviously you could set an end time on IDs and just do it from there.

You can’t get this just from the iNat export, but downloading the observations and then using Excel you can sort by species then time, and then if you remove duplicates Excel will keep the earliest species/time cells. Resort by time at that point and you should be able to make a species accumulation graph. That’s how I’ve done it in the past and it seems to work fine.
