File size problem when performing XML Transformation into Excel

Question

Hi All,
We are performing XML Transformation in ABAP which can open in Excel and saving to common share. But the file size of excel is around 50MB. After opening the excel and save with diffrent name the file is getting compressed and its below 1MB. So what kind of settings does we need to make to the transformation code which will create the excel files with less memory/size??
<?sap.transform simple?>
<tt:transform xmlns:tt="http://www.sap.com/transformation-templates">
<tt:root name="AAAAAAA"/>
<tt:root name="BBBBBBBB"/>
<tt:root name="CCCCCCCC"/>

Hi Raghu,
have a look at the XLSX file generated by Excel, you'll see that it's simply a zipped file. So you can't do it with a transformation, but you need CL_ABAP_ZIP class. I advise you to look at the abap2xslx project ABAP code (currently 3.0) to see how it works.
Best regards,
Sandra
