I am creating a database in which there is one container field.i am exporting all my fields in to excel its showing no problem in other field but in container field its not allowing to export in any format.

Is't possible to export container field in any formats that is available in filemaker.

No.

how about just letting me know if it's empty or not?

Do your container fields contain embedded files or references only?

embedded files so that they can be viewed through IWP

Short answer: no.

You could export the files to a known location (one-by-one, using Export Field Contents[] in a loop), then include links to the exported files in the Excel file. Maybe there is a way in Excel to use these links in order to embed or display the files - but I don't know enough about that.

thanks for taking the time to help me out again.
