How to define InstanceName field in XLS Form


I understand that I can define an instanceName under meta tag of an xml form. Can you please help how can I insert that when designing form with XLS form using Excel sheet??

Does it need to be added in settings seet or somewhere else.

Thank you in anticipation.

I got the solution:

Start by adding a new column to your form's settings worksheet, and entering "instance_name" into the first row of the new column.

Then, in the second row of that new column, add an expression like the following:

concat('HH SURVEY - ', ${hhid})
