Xls files loading issue

[FFBB1983]

Hi Everyone, 

I have the attached .xls. I have been trying to 1) write a script and 2)drag and drop for the autoload. But I can't load in either way. This file appears to be normal when I open from MS Excel. However, when I  save this file as .xlsx, everything is working well.

I saw the trick about "ooxml" and "biff" in the community. I think I didn't make it wrong for this case. I will have to take xls as this is the format from our supplier daily. It's not fun to convert the format before I load every day.

The following are the error msg I got and my script. Any help is very appreciated!!

for each file in filelist('lib://BUSINESS_DROP/LSU3PL\DAILY\*.xls')

CONCATENATE(SALES_TMP)
LSU3PL_DAILY_SALES:
LOAD 'LSU3PL' AS DataSource,
'RETAIL' AS Channel,
'GROSS SALES' AS SalesType,
filetime() AS FileTime,
filename() as FileName,
"Bill-to Name" AS BillToName,
"Sold-to
(Postal Code)" AS PostalCode,
"Product Description" AS ProductDescription,
"Document #" AS OrderNumber,
"Invoice
Date" AS InvoiceDate, 

"Qty
Invoiced" AS InvoicedQty,
"Total" AS TotalSales

FROM [$(file)]
(biff, embedded labels, header is 2 lines, table is Sheet1$)
WHERE NOT ISNULL("Qty
Invoiced")
;

next file

This is the error message I got from the drag and drop view. If anyone knows how to solve this problem. Please help!
