This file contains an undocumented error type, that causes this issue. :

<s t="_error">
<k n="errorType" t="i"/>
<k n="propagated" t="b"/>
<k n="ptg" t="i"/>
</s>

Was this file created using Excel?

[minren118]

Yes, I just use EPPLUS to read and write data, most of the template content is processed by Excel.

Ok, I cant find any documentation of this error type...https://learn.microsoft.com/en-us/openspecs/office_standards/ms-xlsx/2c5dee00-eff2-4b22-92b6-0738acd4475e.
We will rewrite the handling of rich data in EPPlus 8, so we will look at this as part of that.
