Mastering JSON Data Manipulation from Excel in C-

When dealing with data analysis and management, extracting and manipulating data from Excel spreadsheets is a common requirement. In C-, reading data from Excel and converting it to JSON is straightforward, but altering how that JSON data is displayed can be a challenge. If you've found yourself asking, "How can I manipulate how the JSON file displays its data?", you are not alone. In this guide, we’ll explore effective strategies for customizing the structure and display of JSON data generated from Excel spreadsheets.

The Initial Setup

Before diving into code solutions, let’s ensure we’re on the same page regarding the data structure. Here’s what is happening on a high level when we read data from an Excel sheet and convert it to JSON:

Reading the Excel spreadsheet: We read each row and extract values from each cell.

Creating a List of Dictionaries: For each row, we create a dictionary that holds the column names and their corresponding cell values.

Converting to JSON: The collected data is serialized into a JSON format using JsonConvert.SerializeObject().

With the essential steps in mind, let’s look at how we can manipulate the resulting JSON output to meet our needs.

Steps to Manipulate Your JSON Output

Step 1: Read and Structure Your Data

You already have a method for reading from the spreadsheet. Here’s a brief overview of how that process might look:

In this loop, each piece of data is collected into a dictionary.

Step 2: Use JsonProperty for Custom Naming

To display the JSON data in a more user-friendly format, you can utilize the [JsonProperty] attribute from Newtonsoft.Json. This allows you to define names for the properties as they appear in your final JSON output. Here’s how you can modify your InterfaceRecord class:

Step 3: Create Custom Constructors

If you want to serialize with new property names altogether, consider using a JsonConstructor to provide additional flexibility. This approach allows you to define how your properties are populated during deserialization:

Step 4: Final JSON Output

With the above definitions, your JSON data can now be displayed as follows, effectively matching your specifications:

Conclusion

Manipulating the display and structure of JSON data extracted from Excel spreadsheets using C- can significantly enhance data usability and readability. By using the [JsonProperty] attribute and creating custom constructors, you can tailor the output to meet your specific needs. This makes your data more descriptive and aligned with your project’s goals.
