In a report generation software, with the option available “Export as PDF” the reports are exported in PDF formats that can be downloaded. Not quite, whenever the reports were exported to PDF formats, the PDF files lacked readability as there was an improper alignment issue.

When we looked into the improper alignment, we found the issues were due to the default settings of the PDFMake package content. The application collects contents from data centers and generates the PDF report.

We use an API call to invoke the data centres that responds with a . JSON format(encrypted) with a 64 — bit base. Only after the code’s been decoded, it employs the PDFMake Package 0.1.54 to generate the PDF report.

Still, we did not get an expected outcome. Moreover, the report could not be manually aligned. By default, the contents in the report were left aligned. While re checking it was found that the package did not employ the properties “preserveLeadingSpaces and preserveTrailingSpaces”.

An easy and orderly way to save information is through JavaScript Object Notation (JSON). When information is transferred between a browser and a server, it must be in the form of text. Any JavaScript object can be converted to JSON and sent to the server in this manner. Any JSON that you get from the server can also be converted into JavaScript objects. It makes working with the data as JavaScript objects easier because there is no need for laborious parsing and translations. Now that you are aware of what JSON is, let's move on to why we must use it and what JSON's various benefits are.

JSON Syntax

// JSON syntax { "name": "Shailesh", "age": 22, "gender": "male", } The data in JSON is organized into key/value pairs and separated by commas,. JSON is a descendant of JavaScript. Consequently, the JSON syntax is similar to the JavaScript object literal syntax. However, other computer languages can also access and create the JSON format.

Data in JSON

Key/value pairs in JSON data resemble the object attributes in JavaScript. A colon separates the key and values, which are written in double quotes:. For instance, // JSON data "name": "John" Object in JSON A JSON object is enclosed with curly brackets. JSON objects are capable of holding several key/value pairs. For instance, // Object in JSON { "name": "Shailesh", "age": 22 }

Array JSON

Square brackets  are used to denote JSON arrays. For instance, // Array JSON // JSON array containing objects
