Every now and then I "google" through Steemit to see whether someone finally (or again) created a reporting tool so we can export an overview of all the rewards we earned in a year.
Sadly, most of the links are dead ends, but today I came across Accusta by @semasping, which gives me most of what I want to see, actually.
It's easy to export your author- and curation rewards (and more) since the beginning of time in a .csv file.
All you have to do is go to https://steemit.accusta.tk, enter your account name, et voilá!
You'll see your earnings in SBD, STEEM and STEEM POWER displayed in green graphs on top of the page, and as you scroll down, you'll see the overview in list format, as well as a light blue button that says Export Rewards to Excel (csv).
You do have to do quite some fiddling around with the files in order turn them from .csv to readable spreadsheets though. Normally you just click "text to columns" to transform the blob of text to a readable table, but some of the rows start with a semicolon, which screws the whole thing up... :) You can't just do a "replace all semicolons", because the rest of them are needed to know where the columns should be... ugh!
If anyone knows how to do a "if there's a semicolon at the beginning, remove it, but leave all the other semicolons" command - please let me know!! :)
Except for this one point, it's worth checking out!
