Error Exporting Data to xlsx

[roselilly23]

I receive the following error message when trying to export summarized data to xlsx (excel). "Error Exporting Data. Sorry, we couldn't export your visual data right now. Please try again later."

Exporting to csv works fine. I have worked out it was because I had renamed one of the columns in the table " " (space). When I rename to "." it works fine. 

Just putting it out there in case anyone else comes across it.

@roselilly23,

Thanks for your sharing. Generally, it is recommended to use meaningful names for columns in dataset or visual.
