How to read large excel xlsx files in Uipath

I used the EXCEL APPLICATION SCOPE and READ RANGE ACTIVITY using UiPath.Excel.Activities, and also the activities placed in market place from UipathTeams.XLExcel.Activities.
And there is a crash in all of them, It´s not possible to handle such a big excell file without having errors. I use to kill excel process and delay 3 minutes before using these activities.
My CRM aplication only gives me excell files no CSV files. so I need to convert excel to csv files in UiPath .
Thanks for your answer.
