We are successfully generating excel .xslx exports with birt. Unfortunately Excel 2010+2013 prompts an error on opening the generated reports. On my research I found some articles which state, that birt doesn´t generate native excel by default.

On opening the file it says:
"The file could be corrupted or unsafe. Unless you trust its source, don't open it. Do you want to open it anyway?"

The Excel Document is then in read only mode. On activating edit on the xslx file it prompts:
"Excel was able to open the file by repairing or removing the unreadable content"

This is our version defintion in our pom.xml
<dependency>
    <groupId>org.eclipse.birt.runtime</groupId>
    <artifactId>viewservlets</artifactId>
    <version>4.5.0</version>
    <exclusions>
        <exclusion>
            <groupId>org.eclipse.birt.runtime.3_7_1</groupId>
            <artifactId>org.apache.commons.codec</artifactId>
        </exclusion>
    </exclusions>
</dependency>

Is this a known issue? How can I fix it?
