Export data in JSON format
In Power BI Desktop, you can use the R script to convert the data frame into JSON format and export into a JSON file.
1. Configure your R environment. Install readr and jsonlite packages.
2. Drag the fields you want to export into a R visual. Write R script below and Run:
library(readr) library(jsonlite) x<-toJSON(dataset) cat(x) write_lines(x,path = "/Program Files/R/R-3.3.3/write_json.json") plot(dataset)
Ps: The file need to be created first with permission granted to packages.
You can see the generated JSON format data in R studio.
Regards,
can this approached to be used to store historical data from live data streams such as New Relic?
I get live data form NR for past 14 days; we cannot get any longer duration and wont be able to do it in the near future.
However, my client wants more data to be stored in PBI for historical analysis.
They proposed to get data every day (to avoid loading issues) from NR, save it locally and refresh charts daily.
We do not have any automation here except that NR refreshes. Manual refresh of reports and dashboards is not gonna work in long term either.
Any ideas on how to implement the solution if any? v-sihou-msft

This is what we do - we have a snapshot of data that changes every 15 minutes but need to audit specific times later on, so on each query run it ends in a rscript that writes to a .txt in our case (will be changing to json). We can then load that and have a full historical as long as no refreshes missed.
We have it set up to scheduled refresh so the whole thing is automatic. If you turn off "use miltiple processors" you can even control the order the data refreshes in the same report - we have the current run data included in our historical file before pbi loads the historical file on the same refresh.
The historical file is managed/connected through a gateway which has all the r installed.
