JSON vs YAML vs TOML

JSON

JSON (JavaScript Object Notation) is indeed an established standardized data type and database exchange form that stores and transmits data elements made up of attribute-value combinations and ranges using human-readable fonts (or other serializable values). This is a widely used document format with a wide variety of data transfer capabilities, along with the interaction between web apps and servers.

Advantages

JSON consumes less storage than XML and enables hierarchical records. It was also intended to make parsing inputs into local Javascript structures easier, making it particularly helpful for online apps. It’s similar to CSV because it’s accessible and concise, but it also includes hierarchical data like XML. JSON formats are only roughly two times as big as CSV formats, unlike XML.

Disadvantages

Such file format isn’t as widely supported as XML. Because JSON is a fresher format than XML, there are fewer APIs available to change JSON to local programming languages. This is evolving quickly, as modern APIs and extensions accept both XML and JSON.

YAML

YAML is a data encoding software that is commonly used to build programming files and may be used with any computer dialect

YAML is a human-interaction-oriented data encoding tool. JSON, one other data encoding dialect, is a tight superset of it. It can, however, accomplish all of it JSON could do and much more since it is a tight superset. In YAML, newlines and indentation adequately reflect something, but in JSON, brackets, and braces are used.

The format is well-suited to describing the setup, which is exactly what we do at CircleCI.

YAML is quickly becoming the market's favored data serialization and system configuration standard among the industry's newcomers. It's a wise move on their part. YAML has most of the advantages of being as concise as CSON and all of the data format interpretation characteristics of JSON.

Advantages

In YAML, no additional punctuation is required. As a result, it is less heavy than XML and JSON.

The lack of such markers in YAML allows readability easy and quick. YAML simplifies data comprehension. As a result, it is beneficial in the event of configuration.

YAML has a massive range of applications and is widely used. It could be utilized for configuration, material transport, and intermediate data storage.

JSON is superseded by YAML. Yes, you read that correctly. The YAML converter will interpret any acceptable JSON code you provide. So there is one benefit to using YAML over JSON for your projects. With a singular processor, you can decode JSON as well as YAML code.

Disadvantages

It’s difficult for a programmer to substitute XML or JSON with YAML because several apps already use them.

YAML's popularity is far less than that of JSON and TOML.

When developing YAML code, you must take every preventative measure. Your code may quit functioning even if a single gap is mismatched during formatting.

In YAML, there seem to be various approaches to express data and create a data hierarchy. As a result, treating it is difficult.

TOML

TOML stands for “Tom’s Obvious, Minimal Language,” which refers to the program’s founder, Tom Preston-Werner.

The TOML software is program software. It is supposed to map clearly to a dictionary and is designed to be simple to comprehend and type due to straightforward interpretations that strive to be "basic." Its description is fully accessible and is updated by the users. TOML is translated into a variety of computer languages and is utilized in a variety of software applications.

Advantages

Very easily understandable; it is simplistic and straightforward.

Disadvantages

The absence of library compatibility. The links to the files must be hidden.

Conclusion

It’s a lot easier to use than YAML, which is appealing if the setup is straightforward. However, if your configuration contains much hierarchical content, TOML could be too complex, and a language like YAML would be a perfect choice.
