I looked into this and it appears when I re-save your file with Excel it does work.
Which application generated this file?

[yingnierxiao]

mac office 16.9

I opened your file and saved it again with Office 16.0 and had no problems.
Debugging your file it seems the code has problems iterating through all the sheets and the iterating deeper down somewhere else. I suspect "[Content_Types].xml" inside the zip archive is being opened twice like that.

i print log,that is callback from xml lib.

I don't understand what you are trying to say. Can you explain?

Could you try to reproduce your issue with the latest version of XLSX I/O?
If you still gave it please send an .xlsx file that the problem can be reproduced with.
