使用SSIS将SQL导出到Excel（xlsx）？

Question

I'm an SSIS noob (less than a week experience) so please bear with me.
I am running a stored procedure to export its result to an Excel file.

From my research I have found that SSIS's Excel Destination does not play nicely with .xlsx files (can't be xls since I have more than the ~65K rows in the result), but I found that I can use a OLE DB Destination to write to an excel file.

The issue I am seeing is an error message that occurs on run that says:

OLE DB Destination [212]] Error: 
An error occurred while setting up a binding for the "Main Job Notes" column. 
The binding status was "DT_NTEXT"."

The fields that are erroring are coming in as Text Streams ([DT_TEXT]), and since I was getting an error around not being able to convert between unicode and non-unicode, I use a Data Conversion to transform it into a Unicode text stream ([DT_NTEXT])

If it helps at all, my setup is as follows:

Any help would be amazing. Thank you.

You should consider doing this using a script component, keep in mind that when in data flow task you cannot debug directly but you can use mbox snipped to check results. Also keep in mind that excel will always try to suppose your column data types automatically, for example when you try to import a file from excel that one of its columns starts with a number but in the row 3455 there's a character, it will import the column as a number and you will lose the char value, you will find it as null in your database.

I will give you some code to construct the file you need programmatically, maybe it can give you an idea. (This example reads a file as one column, then it will split in as if you chose fixed with delimited values in excel and will output in a csv file.
