The functionality doesn't currently exist in QBO to export a particular bank rec report into excel. You only have the option to print it at this time.
If you really need to get it into an excel version, if you open up the particular reconciliation report you need, Select all the content on the report and Copy, you can Paste it into an excel sheet.
The columns all break correctly from the report, but you will need to format the sheet.
Not an ideal solution, but if you need it, it will work.
