Hmm... I literally just created an AWS bucket that magically creates (i.e. lambda) corresponding .json files for any .xlsx file that gets put there.

I may have used Git if I knew this existed. For now our requirement was that the file be maintained in an Excel format, but this data needs to be consumed by different scripts written in different languages hence the automatic .json conversion.

I see this frequently but I question the choice of JSON which I assume is actually newline delimited JSON objects. What is the benefit of JSON? Familiarity?

If you need to ingest tabular data is JSON the ideal format? Why not something like escaped TSV? I realize storage is cheap but JSON has a lot of overhead and I don't see the benefit in using it to store data files, especially from spreadsheets.

Depending on access patterns something like Parquet may be a lot more useful.
