Encoding and Decoding Data: CSV vs. JSON

In general, CSV (Comma-Separated Values) is more efficient in encoding a table compared to JSON (JavaScript Object Notation). This is because CSV is a simpler and more lightweight format designed specifically for tabular data.

CSV files are easy to read and write, and they typically consume less storage space compared to JSON due to their minimalistic structure. On the other hand, JSON is designed to store and exchange structured data in a more verbose and human-readable format, which includes key-value pairs and nested structures.

If the primary goal is to store tabular data or exchange data in a format optimized for tables, CSV is usually the more efficient choice. However, JSON provides more flexibility and features for handling complex data structures beyond simple tables.

Encoding with PHP

When using PHP to encode data into either CSV or JSON format, the efficiency of encoding tables will largely depend on the specific use case and requirements of your application. Here are some factors to consider:

  1. Encoding Tables into CSV with PHP: PHP provides built-in functions for reading and writing CSV files, making it relatively straightforward to work with tabular data. You can easily generate CSV files from arrays or database query results using functions like fputcsv(). CSV remains a simple and efficient choice for storing table-like data using PHP.

  2. Encoding Data into JSON with PHP: PHP also has built-in functions to encode data into JSON format, like json_encode(). While JSON is more verbose than CSV, it provides flexibility in encoding complex data structures beyond tabular data. If you need to serialize multidimensional arrays or store nested data, JSON might be a better choice.

Ultimately, the choice between CSV and JSON in PHP will depend on your specific requirements. If your data is primarily tabular, CSV might be more efficient. If you need to handle more complex data structures or require interoperability with other systems that use JSON, then JSON might be the more suitable option.

Will Power Query still prefer CSV?

Yes, CSV is generally considered more efficient when parsing data into Power Query compared to JSON. Power Query is a data connection technology that allows you to discover, connect, transform, and load data for analysis in tools like Microsoft Excel and Power BI.

CSV files are a common and compatible format for importing data into Power Query. Power Query has native support for CSV files, making it easy to read and process tabular data stored in CSV format. CSV files are often used for straightforward data import tasks in Power Query because of their simplicity and efficiency for tabular data.

While Power Query also supports processing JSON data, importing JSON files can sometimes require additional steps, especially when dealing with nested structures and complex data formats. In such cases, using CSV for data import tasks in Power Query may be more straightforward and efficient.
