I understand from this help guide, that in order to utilize the Geo Data Visualization (Map Charts) the data field needs to be recognized as a geographical data type. For example, column Longitude needs to be data type = Longitude. The instructions demonstrate that right clicking on a data field name will provide a "Change Data Type" option but I do not see this in our database/workspace.

I need to update our Address, City, State, Zipcode, County and Country fields to not be seen as text fields and instead be recognized as geographical information so Zoho Reports can then use to produce a map chart. How do I do this?
