Select Wallets -> Add new (or choose existing wallet if you've done this before).
Name wallet something like "Terra"
Select Accointing Template -> Continue
Upload .xlsx file
All transactions starting with underscore are omitted from the Accointing .xlsx (i.e. _LP_WITHDRAW). This means these transactions must be imported into Accointing manually (or ignored where appropriate).
Can I import .xlsx multiple times?
Multiple imports causes duplicates on Accointing. To remedy, there are two options:
Edit CSV (i.e. google sheets), such that only new transactions exist.
Upload edited CSV
Delete all transactions for the previous import(s)
