question

"I would like to place FlexSim in a server, and the local user execute webserver and import their excel file by using webserver...."

FlexSim running on the server cannot access a file from the client's computer. You will need to do some web development to make it so that the client can upload the file to the server that FlexSim is running on if you want FlexSim to be able to import that file. This type of web development work is beyond the scope of technical support.

"besides... once I import excel I have some post import code.. is that also taking into account in webserver?"

Yes, FlexSim will run exactly the same on the server as it does when you run it locally. You can execute whatever code you want in FlexSim, and it will execute it. Whatever that post import code does will happen on the server though, not on the machine that is requesting an HTML response from the server.

As Matt pointed out, the default page that is returned when you connect to a FlexSim instance through the webserver has been upgraded in FlexSim 16.2.

In 16.2, it gives you back an interface that resembles the windows that are open in the model you connected to, including Dashboards and Dashboard buttons. This makes it really easy to execute FlexScript code on the webserver by simply attaching it to a button on a dashboard:

If you don't want to use that default page for interacting with a model, you can customize the defaultpage HTML that is returned by adding nodes to the Tools folder in the model tree, as explained in the User Manual section Miscellaneous Concepts > Webserver > Concepts > Developing custom web interfaces.

Attached (customwebserverexample-v16-0.fsm) is an example model built with FlexSim 16.0 that demonstrates this.

It has a custom defaultpagetemplate.

It has added two Javascript functions and two HTML buttons that execute those Javascript functions.

Extra Javascript functions have been added on lines 41-55 as an example of how to send custom queries to the server.

Lines 122-127 have added buttons and inputs for changing the arrival time and cycle time and executing the extra Javascript functions.

Those functions send queries to FlexSim that are handled by custom query handlers in the tree that execute FlexScript code.

The queryhandlers have code that set global table values. The cycle and arrival times in the model are set to read those global table values. I did this as an example; you could use whatever Flexscript code you want to modify your model in whatever way you want, such as running an Excel import.

Also, on the old forum, I posted an example php website that interacts with the FlexSim webserver instead of using the default index.html page that is served up by the flexsimserver.exe. You can download this website and see how it interacts with the FlexSim webserver through this link: https://www.flexsim.com/community/forum/showthread.php?t=2916

That's another way to write custom server-side logic, such as user authentication, file upload, etc.
