I have upgraded to latest version to see if the issue continues, and it does.
I saw it reproduced in your site.
Enter Format cells => Add nullValue as “&” sign and apply it to all values.
Enter Format cells => nullValues become “$amp;”. apply it again.
Enter Format cells => nullValues become “$amp;amp;”.
and so on…
Please let me know when you fix it.
P.S. We have several licences of your library.
Thank you for posting your question here.
The issue is also reproducible on our side.
The necessary fix will be released in minor update with ETA Jul 15.
Also, could you please specify what company you are representing? We need this information for our records.
I work at Cooladata. I’m representing this company.
Waiting for your new release,
wish you the best,
