I just noticed while answering a question on the Lianja forum that Stimulsoft imports VFP Reports:
https://github.com/stimulsoft/Importing.ToolsI looked at Stimulsoft (and will likely use them) to run our Crystal Reports (we have many, many) using Reports.JS, as the viewer will run in a webview section in Lianja, getting its data in oData format from the Lianja Cloud Server.
However, they have many other versions of the Report Viewer, including their newest in .NET Core.
They are good to work with. For example, in assessing whether they could convert our Crystal Reports, they were willing to test out samples for us. I found that pretty remarkable.
