Enter "csv" into search and click the "Import from CSV" button that shows up.
Finish import according to instructions.
All transactions starting with underscore are omitted from the Cointracker CSV (i.e. _LP_WITHDRAW). This means these transactions must be imported into Cointracker manually (or ignored where appropriate).
Can I import CSV multiple times?
Multiple imports causes duplicates on zenledger. 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)
