Merging multiple level JSON correctly

[fitwist]

1. Case data: https://csvjson.com/json2csv/8e252e26d7d4843fe02471981ed2111f

2. How do I get a table, where purchase history (product name, quantity, price) has enough columns for all positions, not messing with the following purchase meta data? In other words, when I try to convert a file where a single item has up to six levels, csvjson.com puts all 'ticket.document.receipt.items.name' and its siblings and appends upper level properties without any placeholder. It makes output a mess.
