@jan_blaha Thank you for your reply.

I did all the work adding and replacing the Xlsx. If you're intereseted, i can share with you guys the work i did. (Maybe it can help other developers, 'cause i see a lot of topics with "dynamic" on title.)

Hello,
I'm trying to dynamically format my xlsx, depending the type data received through API call.
I'm not using any pre inserted asset. Is it possibile to achieve this kind of approach?

Also, am i using xlsxColAutofit correctly?

I'm using my own style, and sending the columns and rows through API call.

Here's my example: https://playground.jsreport.net/w/MatheusBaretta/or056N8k

Thank you!
