Hi Clarice,

Thank you for your response.

When I tried this, XLSX Converter generates the following error -  
_Error: Error: Invalid or unexpected token interpreting formula: data(‘mobileNumber’)\<9 on sheet: calculates row: 2 column: calculation_

The screenshot -

I did notice that the syntax with the single quotes works in other example forms included with Application Designer. Still looking for a solution.

Thanks,  
Satish
