The OP's spec, as quoted earlier(!), reads:

"It's my own research, so I can give myself the data in any format that
I like."

Whither "files are exchanged" and/or "multiple parties"? Are these
anticipations of problems that may/won't ever apply? aka YAGNI.

Concern about such an approach *is* warranted.

However, the preceding question to be considered during the design-stage
is: 'does such concern apply?'. The OP describes full and unique agency.
Accordingly, "KISS"!

NB my personal choice would likely be JSON or YAML, but see reservations
(eg @Chris) - and with greater relevance: shouldn't we consider the OP's
'learning curve'?
(such deduced only from OP's subsequent reactions/responses 'here' -
with any and all due apologies)
