And with regard to the spreadsheet: I have now tried presenting my data (from Google Sheets) in #Airtable or #Grist (because both look pretty), but both don't sync with the sourca data.
Next I tried connecting #Sheets to #DataTables (because that's open and also pretty), but that doesn't work either.
Now I'm trying to visualize my raw data with #DataTables, but that's still difficult. I need a no-code solution and really, #Google is so useful, although many here don't like to hear it.
