Problem with reading arrays from JSON

Danylo Pertsov's icon

My friends lunched a site with various statistic data for art makers. Unfortunately, I cannot read their data files - import function for dict object give me -1, JSON.parse in js shows an error in max console, I tried a dump from text with \\d+ in regexp - no results. Have someone some ideas how to work with that stuff? https://pandemic-media-space.com/
