Users are able to change the formatting of Number data type columns with the “localization” settings within the Edit Column Properties option on a dataset.
This gives users the ability to choose the format to match their locale standard. For instance, they can set 1.000,00 for their numbers instead of the default of 1,000.00.
When you use the API, the number format will follow the web-standard format of no commas with a dot separating the integer and fractional portions. For example, the 1.000,00 above would be displayed as 1000.00 in the API.
Data & Insights follows best-practice web standards, such as the JSON specification (http://www.json.org/) and the XML specification (https://www.w3.org/TR/xmlschema-2/#double), in order to ensure that customer data is encoded in a way that will allow developers and other systems to easily consume and use data.
