I need export metadata from documents library when you view content as table it will get content with metadata I wish to export this table to excel without content only text on the table.
You've told us what you are trying to do. Now tell us what you have tried, what error messages you are seeing, or what specifically you need help with.
I tried to add A.A.A.R extension but this tools give me report for size content or users I need something to export metadata from table view on Document Library.
My understanding is that the AAAR extension can be used to report on any metadata in the repository, not just on content or users. So you might ask the maintainers of that project for help on how to do that.
Alternatively, you could grab a CMIS library from http://chemistry.apache.org and use it to query the repository and write the data to a CSV.
