Using LibreOffice/OpenOffice from JAVA to convert File Formats

Question

I'm using LibreOffice4.0 UNO to convert files. I managed converting between doc and docx, from xlsx to xls and from docx to doc, but I'm having trouble finding the FilterName value for XLSX and PPTX.

propertyValues[0] = new PropertyValue();
propertyValues[0].Name = "FilterName";
propertyValues[0].Value = "...";

for doc I used:  "swriter: MS Word 97";
for docx I used: "Office Open XML Text";
for xls I used:  "swriter: MS Excel 97";
for ppt I used:  "swriter: MS PowerPoint 97";

Thanks.

Answer 1

For XLSX you can use either Calc MS Excel 2007 XML or MS Excel 2007 XML.

I also found this for OpenOffice but I'm not sure if it works for your case:

DOCX - MS Word 2007 XML 
XLSX - Calc MS Excel 2007 XML 
PPTX - Impress MS PowerPoint 2007 XML

There is a BIG list here
