How to reference a list of instruments stored in Excel and how to display financial period in CH?

Bianca01

1. How to edit the syntax so that it will reference an Excel file containing up to 250 RICs?
2. How to edit the syntax so that it will display the financial period in the columns (e.g. FY2018Q1, FQ2018Q2, and so on). Tried adding 'CH': 'Fd,Fperiod' but it did not work.

This is what I am currently working on:

import refinitiv.data as rd
rd.open_session()
df = rd.get_data(
universe = ['ORCL.K'],
fields = [
'TR.RevenueActValue(Period=1FQ2018:1FQ2025,Curn=USD)',
'TR.EBITDAActValue(Period=1FQ2018:1FQ2025,Curn=USD)',
'TR.NetProfitActValue(Period=1FQ2018:1FQ2025,Curn=USD)'
],
parameters = {
'Curn': 'USD',
'CH': 'Fd,Fperiod'
}
)

display(df)

Thank you in advance!
