Lumeer.io offers an ideal mix of functions from, for example, MS Excel, Ms Access, Word, MS project, Google Calendar, Google Maps, Kanban/Trello and Visual Basic scripts in one. All my data is securely encrypted and sent back and forth over the internet to a GDPR compliant data center in Germany. And if I want, I can download all my data, data definitions and scripts to a JSON file and switch to another package that way. So no vendor lock-in. For IT techies: Lumeer's code is available on Github. The basic version of Lumeer is free to use forever. Review collected by and hosted on G2.com.
It has to get used to linking tables on the lumear to be linked to each other and to view and mutate in Spreadsheet View.

But if you go through it, almost every administrative process can be automated via lumer. Review collected by and hosted on G2.com.
