There's a new listener EA released today go grab it and try out. There's 2 real changes. First the MIME_TYPE on file uploads is fixed.
The second is a result of sitting down at RMOUG last week and talking over the excel parsing with Scott. That conversation resulted in a few new knobs to change some configuration options.
1) I found an API which takes the item_id and gives back the item_name so the collection will default to the ITEM_NAME of the file upload item.
2) Files ending with .xls OR .xlsx will be processed.
3) Several new configuration choices: a) First is a new config option to have 1 sheet of the workbook per collection. This is controlled by <entry key="apex.excel2collection.onecollection">true|false</entry>
b) Then, you can essentially hard code a collection name to be used for all excel uploads. <entry key="apex.excel2collection.name">MY_COLLECTION_NAME</entry>
c) Lastly, an option to use the sheet name vs. a sequential WORKSHEET:1,2,3.... <entry key="apex.excel2collection.useSheetName">true|false</entry>
So, here's a recap of excel parsing with the APEX Listener
Step 1: Turn it on <entry key="apex.excel2collection">true</entry> Step 2: The request of the upload must be : xls2collection
This will get you ONE collection which contains all sheets in the workbook and the collection will be named the APEX Item name.
