Office File Creator can output or save files from the ListView. The setup procedure is described below.
Create Visualforce page
From Settings, select Custom Code > Visualforce pages, click the "New" button on the Visualforce screen, and paste the following code.
<apex:page standardController="Opportunity" recordSetVar="sobjects" standardStylesheets="false" sidebar="false">
<script type="text/javascript">
var retUrl = "{!$CurrentPage.Url}";
retUrl = retUrl.substr(retUrl.indexOf('%2Flightning%2Fo%2F'));
var getIds = "{!selected}";
getIds = getIds.replace('[', '').replace(']', '');
getIds = getIds.replaceAll(' ', '');
var url = "/apex/ofc2__OFCOut?ns=ofc2&template=TemplateApiName&id="
+ getIds
+ "&retUrl=" + retUrl
+ "&redirect=false&showLoadingMsg=true"
+ "&isBulk=true";
var link = document.createElement('a');
link.href = url;
document.body.appendChild(link);
link.click();
</script>
</apex:page>Replace "Opportunity" in the first line "standardController="Opportunity"" with the name of the object API to be output.
Then, copy the Custom Button URL (Export to File) in the OFC template record from the beginning to "&id=".
Paste after "var url=" on line 10.
To save to a file or attachment instead of outputting to a file, add "+"&save=file" or "+"&save=att" to the next line of line 12.
+ "&retUrl=" + retUrl
+ "&save=file"
+ "&redirect=false&showLoadingMsg=true"
+ "&isBulk=true";
Save the Visualforce page under any name.
