Use POI to parse Excel but got exception “Invalid Header Signature”

Question

I was trying to use Apache POI (Version 3.6) to parse Excel .xls file, but got only Exception:

java.io.IOException: Invalid header signature; read 0x07B1FD12         


        

Answer 1

Just an idea, if you using maven make sure in the resource tag filtering is set to false. Otherwise maven tends to corrupt xls files in the copying phase in in your pom.xml
