"How to save an excel worksheet to .aml file"

Hi,
this is quite simple: Use an ExcelExampleSource and after loading it, use an ExampleSetWriter to write it into an .aml file.

This would look something like this:

<operator name="Root" class="Process" expanded="yes">
    <operator name="ExcelExampleSource" class="ExcelExampleSource">
    </operator>
    <operator name="ExampleSetWriter" class="ExampleSetWriter">
    </operator>
</operator>

Greetings,
