Sounds weird a little bit, rsennett_splunk is right, ms query is related with Excel. Maybe you are confused...If you meant Excel, read this then: You can include only one table in your query. Each table corresponds to a report (saved search in Splunk Enterprise 5) in Splunk. If your table doesn't include the columns you want, verify in Splunk that the corresponding report is returning the results you expect, and modify the query if necessary.
If it is really an Adobe Illustrator files, verify them first of all. Do they open correctly? Do you get an error while opening it? I suppose the problem isn't in Splunk either.
If your .ai files are corrupt then run ContentRecovery. To do it manually read this: http://www.filerepairforum.com/forum/adobe/adobe-aa/illustratoor/1887-data-retrieval-from-a-damaged-ai-file
and then you will be sure that all the files are fine, write about the results again
