When I am loading an excel file from a remote server, I am facing an error in talend : “Unable to recognize OLE stream”. Can I convert this file from xls to xlsx in talend? I tried by renaming the extension to xlsx in the tFileInputconvert but it doesn't read then. I can convert to xlsx by saving it as xlsx but the file is on some server through which the data is being loaded into the postgresql tables. Is it possible to convert this file to xlsx or write some java code in talend to make it "Save as" xlsx ?
