Create a txt file from the data in the excel sheet

Hello,
I need your help to export to a text file the information in the sheet "Detail".
- The Head of the text file is in my script. Only the date in that header changes, it is the day wich the text file is created.
- Records detail (0602): There are many records as rows in the Sheet.
- A total record (0802): This is the last of the table and it is described only once in the text file.

The empty spaces are part of the txt file and space should match the field length considering a space is a character.
As below

The reserve1 field = String (8, Chr (160).

Sorry for my English.

Regards.
