I am building a flow which ingests two different type of files, both containing FX rates (e.g. USD to EUR, USD to GBP, EUR to SEK, etc.), converts them to the same format and then passes them on to other child flows.

I've managed to do all the data manipulation necessary, but during UAT I have run into two issues:

The two different filetypes contain different pairs. One contains only pairs with USD, the other contains mostly EUR based pairs. E.g. one file has as USD/GBP pair and the other has EUR/GBP.

The output child flows also expect the different type of pairs. One would expect for instance only USD based pairs, only EUR based pairs, or even mixed.

I'm allowed to freely pivot over the USD/EUR rate that's in the file. I have some ideas on how to approach this, but I feel a bit in over my head and hope there's some wizards here with some advice.

My current idea is to initialize a JSON object with all the expected pairs for each output (there's 3 or 4 flavours of FX pairs for 6 output formats) and then fill the FX Rate (float) value using an apply to each loop. Within the apply to each loop I determine whether the desired FX pair is in the source or if it needs to be pivotted on the USDEUR pair. I'm not sure what's the most efficient way to intialize this JSON object, aside from typing it up manually.

There's also one pair, AUD/NZD, that needs to be calculated from USD/AUD and USD/NZD, so there's a double pivot in there. This would result in three types of calculations for FX Rates (no transformation, pivot over USD/EUR and double pivot).

Attached are some sample source files.

Here's another example of expected output csv files (I can only attach 3 files to the post):

Another expected output is the Source1 CSV.TXT, but then it's expected as output when the input is source2.

Happy to hear any suggestions. Much appreciated!
