Troubleshooting Google Colab: Fixing utf-8 Encoding Issues When Importing CSV Files

Have you ever run into the frustrating issue of Google Colab not being able to read your imported CSV file from your desktop? You're not alone. Many users encounter similar problems when trying to load data from their local machines into Colab.

In this post, we will explore the common errors associated with file importing in Google Colab and provide you with a clear, step-by-step solution to overcome them.

The Problem

The specific error you're encountering is:

[[See Video to Reveal this Text or Code Snippet]]

This error indicates that the data within your CSV file is not encoded in UTF-8, which is the default encoding that Pandas uses when attempting to read CSV files.

While sample data from Colab typically works without issues, CSV files downloaded from other sources may have different encodings, leading to such read errors.

Understanding the Encoding Issue

CSV files may come from various sources and can be encoded in different text formats, such as:

UTF-8

Windows-1252 (often used in Microsoft products)

ISO-8859-1

When you try to read a CSV file with the wrong encoding, it can lead to utf-8 decode errors like the one you're experiencing.

The Solution

To resolve this issue, you'll need to specify the correct encoding when using the read_csv function in Pandas. For many CSV files, especially those generated by Microsoft Excel, the windows-1252 encoding is often the correct choice.

Step-by-Step Instructions
