Export your transaction history from WealthSimple as a CSV file.
Step 1a:
Go to the user-settings Document page
Step 1b:
Click on "Request Documents" and choose `Holdings Report`.
note: I suggest selecting 1 account at a time as I ignore the account column in the CSV.
Step 2:
Upload the CSV file using the "Drag and drop" area above or by clicking to select the file or by copy and pasting the CSV into the input field and clicking "Process Textbox Input"
Step 3:
Once processed, click the "Download Result" button to get your converted CSV file for Yahoo Finance.
Step 4:
Import the downloaded CSV file into your Yahoo Finance account.
There are some example files in the `examples` folder you can use to test the converter.
