If you had Binance Convert transactions from the last 6 months, follow this guide to export the Binance Convert History file.
Note: Due to limitations from Binance this file import method only pulls in Convert trades made in the last 6 months. If you had Convert transactions from before the last 6 months you can add these manually following this guide.
From the Orders dropdown menu, select Convert History and click on Export
Select Past 6 months and click Export
You will receive files in .xlsx format.
Navigate to Step 1. Import and open up a Binance import tab. Click on Upload File and drag your XLSX file into the box to import your transactions.
Note: It's important not to open the file before you import it as Excel can cause formatting changes to the file that prevent it from importing
