Add files via upload

I created a new parameter in the read procedure to print the null cells from the XLSX file in the result set of the function. To achieve this, I developed an algorithm to print the cells before displaying a cell extracted from the XLSX file.

The function ‘get_next_cell’ was modified as advised by the package creator. I changed the function to avoid using the unknown array type. Instead, I utilized functions from the package itself to retrieve the next cell (using the ASCII table).

To provide some context, in my current job, I developed a process to convert XLSX files to CSV files (one file per tab).

Would a simple pivot query not be easier for creating a CSV?
with csv as ( select row_nr, col_nr, to_char( string_val ) v
from table( as_xlsx.read( as_xlsx.file2blob( 'MY_DIR', 'my.xlsx' ), '1' ) )
)
select *
from csv
pivot ( min(v) v for col_nr in ( 1,2,3,4,5,6,7,8,9,10) )

Yes, it's true if I know how many columns there are in each tab page. For my purpose, I need to convert a lot of XLSX files, using the same piece of code (ODI).
