Convert a Text File to JSON using PowerShell: A Step-by-Step Guide

In the world of cloud storage, especially with AWS S3, it's common to manage various log files that contain critical information about storage buckets and their activities. However, these logs are often in a plain text format, which can make them difficult to analyze. If you're looking to convert your log information into a more structured format like JSON, this guide will guide you through how to do this using PowerShell.

The Challenge: Need for JSON Format

When working with AWS S3, logs can be detailed and structured but still come in a cumbersome format. In your case, the bucket information is being logged in text format, and there's a desire to convert this to JSON. The original log file may look something like this:

Breaking down this information manually can be tedious. However, with PowerShell, we can automate this task efficiently.

The Solution: Utilizing PowerShell

Step 1: Define the Columns

The first step is to define the structure of your log. We will set the columns that correspond to each piece of information in the log based on its content. In PowerShell, this is done by creating an array of headers.

Step 2: Parse the Log Data

Next, you will take the raw log data and parse it into structured format using ConvertFrom-Csv. Since the log entries are space-delimited, this can be accomplished easily.

Here's how you can define the log data and parse it:
