Notable Features and Qualities of Our Online JSON Validator/Formatter

Our JSON checker tool has numerous unique and innovative features that distinguish it from its competitors. Check them out below to understand the uniqueness of this tool.

Validate JSON Mode

JSON files are susceptible to syntax errors, which can make them difficult to use, as programs are unable to decode them. 

With our JSON validator, you can easily check your files for syntax and space errors and correct them. The errors are highlighted along with their line number and error type. 

JSON Beautifier Mode

JSON files are flexible in their format. You can write them in a highly concise manner or write them in an elegant and organized way. With the JSON beautifier, you can easily reformat any minified JSON code into beautiful and neatly formatted code with a single click.

JSON Minifier Mode

The JSON minifier allows you to reduce the perceived size of a JSON file by removing all unnecessary line breaks, indentations, and spaces. This is necessary for sending JSON files over networks and for compact storage.

Tree View 

JSON files are typically used to create data structures for storing information. Our JSON format checker enables you to view JSON files in an interactive tree view, which helps highlight nested data structures.

Ideal for programmers seeking to comprehend intricate JSON data structures.

Tab Space

You can set the number of tab spaces you want to add in each line of your JSON file. Tab spaces don’t serve any programming function and are mostly used for enhancing the readability of the file. You can choose to add from one to ten tab spaces in your file.

Web developers can utilize the JSON validator function in our tool to verify their JSON files for errors and bugs, thereby preventing complications in API calls.

APIs also send data in the form of minified JSON files. Developers can validate this JSON online using our tool and check if an API is returning the correct data. Some reformatting and beautifying also go a long way in boosting the understanding of the JSON data.

Formatting Server Logs

Many SaaS applications utilize cloud infrastructure, such as Microsoft Azure and Amazon Web Services. These platforms and other modern servers often output logs in JSON file format.

Developers and system administrators can use our tool to quickly validate these JSON files and utilize the beautifier function to make them more readable.

With our JSON formatter, developers can:

  • Minimize config files for easier parsing and transport.
  • Beautify files to make them easier to read and understand.
  • Validate files to check for errors.

These are all useful operations that developers can use to verify JSON config files.
