Only last line is exported in JSON

[sailgrib]

Hi,

When trying to export data in JSON, only the last is actually exported.
I have tried on multiple Google Sheets with the same result.
I have left all the default parameters and I am exporting only the Current sheet.

You don't have Nested Elements enabled? This issue sounds like an output using nested elements without using proper key syntax.

Would you be able to link to an example sheet?

Closing this issue as it seems to be the expected behavior when Nested Elements is enabled with incorrect key formatting.
