I have a Json File ,what steps should I take to upload in Domo to analyze data
There are a few connectors you could look at: JSON No Code Connector: https://domo-support.domo.com/s/article/360043433473 JSON Advanced Connector: https://domo-support.domo.com/s/article/360042932034
If it's a local file and you need to do it on a scheduled basis, check out Domo Workbench it has a JSON Local File option.
Colemen's answer refers to having json coming through an API. As Jason mentions, the workbench can simply load it in from a file. Find Domo Workbench under Admin > Tools.
