Data formatting
Local JSON Formatter for Mac and iOS
Pretty-print and format JSON for easier inspection and editing. Blissum keeps this utility local on macOS, iPhone, and iPad so you do not have to paste code, tokens, certificates, URLs, or private text into random online tools.
A private alternative to online json formatter tools
Paste raw JSON and format it into readable, pretty-printed output with syntax-highlighted results. Blissum is built for quick inspection of API responses, config files, test fixtures, and copied payloads while keeping tokens, user data, and internal structures on your device. It is the local Mac, iPhone, and iPad alternative to online JSON beautifiers that ask you to paste sensitive payloads into a webpage.
Blissum groups everyday code, text, data, and web utilities into one local app for Mac, iPhone, and iPad, which is especially useful where iOS has fewer native developer-tool options.
