JSON is great for APIs and structured data, but reviewing large responses in raw format gets painful fast.
I kept running into this while debugging APIs, checking exported records, and reviewing nested logs.
Most of the time, I didn’t actually need the raw JSON. I needed something readable.
Converting JSON into a spreadsheet ended up being the fastest workflow for things like:
API debugging
exported records
nested logs
sharing structured data with non-technical teams
One thing I noticed is that nested JSON matters a lot more than people expect. A lot of converters technically work, but still leave deeply nested fields unreadable.
So I built a lightweight browser-side workflow for flattening JSON into readable spreadsheet columns.
It supports:
JSON → XLSX
nested JSON flattening
browser-side processing
no signup
I also added XLS export because some older Excel workflows still depend on it.
