Hi @vishal.kak ,

Ideally you can use the symbology call in the Eikon Aata API to get the symbol conversion. E.g:

ek.get_symbology(
    ['US5949181045', 'US02079K1079', 'US4592001014'], 
    from_symbol_type='ISIN', 
    to_symbol_type='RIC')

However, this might not work when using ISIN as a source, since there is a one to many mapping, and no best match.

I would recommend that you speak with Eikon content experts at my.refinitiv.com to see if there is another means to do this.

Update: You can use the get_data call to get the SEDOL using this call:

Thanks for your response

Why am I getting "No best match available" error when I try to search for Microsft ISIN - US5949181045

df = ek.get_symbology("US5949181045", from_symbol_type="ISIN", to_symbol_type="SEDOL")

perfect, that worked - thanks
