VMware By Broadcom Workstation doesn't include a virtual appliance format converter.
There are converter utilities e.g. qemu-img, vboxmanage, etc. to handle a virtual appliance conversion. Keep in mind that those converter do nothing for target optimizations e.g. low code for optimized storage/network drivers, precision timer, etc. Typically when starting journalctl, dmesg, etc. you see plenty of issues because of unoptimized conversion. Therefore, better use the recommended vendor package for hyper-v, for vSphere, etc. Once deployed, think of reliabilty, backup and business continuity management.
VMware By Broadcom Bitnami typically uses .ova format for appliances on vSphere, but most people do not know, that they offer the same on Azure as well.

Therefore, forget admin-standalone conversion tasks. This is so yesterday.
