Smart marker - html - is throwing exception

I’m trying to insert the smart marker as “HTML” (https://docs.aspose.com/cells/net/using-smart-markers/#using-html-property-of-smart-markers ) so the data will be rendered automatically.
but for some reason, I get a exception while processing the file,

attached template and data. I’m trying to set the “datarowa” property from the JSON (this is some test after the old property name was ContentAsHtmlTemplate and I thought maybe since this sounds as boolean maybe I got that error…

Edit. here some another try with a different template, I tried it in the column. this is printing the JSON instead of the data. not sure what I’m missing here. https://easyupload.io/tixown (zip with data, and exported pdf)

Thanks for the template file and resource files.

We will evaluate your issue and get back to you soon.

1, Please verify your json file is correct. Please check whether Double quotes is excepted before brackets in “reportDataRows”: "[
2,Html smart marker is used to input rich formatted text with html tag as abcd
Html smart marker can not process complex html string.

in the first option, I took that to the next stage,
but on the second try, I’ve tried to send either
the value was: somename.
not sure this is complex HTML. the report printed the JSON instead of the values.

Please check the attached simple html smarker case.

I did the same as you provided, in my template, but still I see JSON in the columns.
what is the different? my property looks like: &=data.employee.firstNameHtmlFormatting(HTML, copystyle,noadd)
this is the same as in the template you provided.

Thanks for your template file, JSON data and output file.

We will evaluate it and get back to you soon.

Can you upload a runnable project, this seems to be a problem with parsing json。

Hi, I’ve changed the way of the structeing data
We used the multiple “branches” ( data.user.transactions.info.etc) and that cased probably the issue with the json.
so we changed the structure to be flated, which means now we have data.user_transaction_order_id
and this is work better. and the JSON is not presented.
