📚 TLDR (Too Long; Don't Read) is a monthly post to help you discover some great and innovative github projects, youtube channels or blog posts.

Today's episode is about : a tool to visualize JSON data, an alternative to Microsoft Office, a script language, an alternative to Pastebin and a tool to draw data flows.

It's with mixed emotions that I announce the end of the TLDR series. While it's been a pleasure sharing bite-sized summaries of various topics with you all, it's time to close this chapter and move on to new endeavors.
Although TLDR is coming to a close, rest assured that I have many exciting plans in store for the future of Needlify. I look forward to continuing to share my thoughts and insights with you all through new and exciting content.
Thank you again for your support, and I hope you'll stay tuned for what's to come.

JSON Crack

JSON files are a very good way to schematize data in a condensed form. This type of file can be used to share data from an API, following an export from a database, ...

However, understanding the structure of this type of file can be complicated when they are large. The more fields are available, the larger the file will be and the less understandable it will be. Fortunately for us, there is a tool that allows us to decompose the fields of a JSON file recursively.

JSON Crack is a web application that, from a JSON content (file or simple text), allows to represent its structure as a graph. In this way, you can understand the structure, the sequence between each field, ... This tool can be particularly useful for large JSON files.


It can be especially frustrating to lose data such as photos, videos that you care about. It can be family photos or even work documents.
