Adding Several Blockchain Addresses Efficiently

I have several hundred standalone cold storage bitcoin blockchain wallets (that I created at bitaddress.org). Putting them in Koinly one at a time is for the birds. Can these be put into a CSV file without too much effort and then successfully imported? My significant research of the use of CSV files for Koinly import did not give me insight on how to do this.

I hope someone can give some guidance on this.

I have since learned that I can enter up to 100 blockchain addresses at a time through the manual feature if they are each separated by a comma.

So what I did is I took my listing of my several hundred wallets and broke them down into sub 100 chunks. Each chunk was in a column, so I used the Excel “transpose” function so they would all be in one row. I then saved this one row of info (with everything else deleted) as a CSV file. From there, I then reopened the file in word. It was in a nice literal comma separated format which I could copy/paste into Koinly. It seemed to work well.
