Understanding and Fixing Excel Files with Weird Characters (XLS Extension)

Have you ever encountered an Excel file with weird characters, making it impossible to read or work with? You’re not alone! In this comprehensive guide, we’ll dive into the world of Excel file extensions, specifically the XLS file type, and explore the reasons behind weird characters appearing in your files. We’ll also provide step-by-step instructions on how to fix and prevent these issues from occurring in the future.

What is an XLS File?

An XLS file is a type of Excel file that uses the Binary Interchange File Format (BIFF) to store data. It’s an older file format that was used by Microsoft Excel until the release of Excel 2007, when the XLSX file format became the new standard. Despite being replaced, XLS files are still widely used, and their quirky behavior can sometimes lead to the appearance of weird characters.

Why Do Weird Characters Appear in Excel Files (XLS)?

There are several reasons why weird characters might appear in your Excel files:

• Character Encoding Issues: When an Excel file is created or edited on a system with a different character encoding, weird characters can appear. This is because the encoding doesn’t match the system’s default encoding, causing characters to be misinterpreted.
• Font Issues: Using a font that’s not compatible with the system or not installed can lead to weird characters appearing in your Excel file.
• Special Characters and Symbols: Excel has a limited set of characters and symbols it can handle. When you try to use special characters or symbols not supported by Excel, they might be replaced with weird characters.
• Data Corruption: File corruption can occur due to various reasons like power failures, software crashes, or file transfer errors. This can cause weird characters to appear in your Excel file.

Fixing Weird Characters in Excel Files (XLS)

Now that we’ve identified the possible causes, let’s get to fixing those weird characters!

Method 1: Change the Character Encoding

Try changing the character encoding to match the system’s default encoding:

1. Open your Excel file in Notepad or a text editor.
2. Save the file with a different encoding (e.g., UTF-8 or ANSI).
3. Open the file again in Excel to see if the weird characters have disappeared.

    Example: Saving a file in Notepad with UTF-8 encoding
    File -> Save As -> Encoding: UTF-8

Method 2: Replace Font

If font issues are causing the weird characters, try replacing the font:

1. Open your Excel file and select the cells containing weird characters.
2. Go to the Home tab and click on the Fonts dropdown.
3. Select a different font that’s compatible with your system (e.g., Arial or Calibri).
4. Apply the new font to the selected cells.

    Example: Replacing font in Excel
    Home tab -> Fonts -> Select new font (e.g., Arial)

Method 3: Remove Special Characters and Symbols

If special characters and symbols are causing the issue, try removing them:

1. Open your Excel file and select the cells containing weird characters.
2. Go to the Home tab and click on the Find & Select dropdown.
3. Select Replace.
4. In the Find what field, enter the special character or symbol.
5. In the Replace with field, leave it blank or enter a replacement character.
6. Click Replace All to remove the character.

    Example: Replacing special characters in Excel
    Home tab -> Find & Select -> Replace -> Find what: ∞ -> Replace with: (blank)

Method 4: Repair and Recovery

If data corruption is the culprit, try repairing and recovering your Excel file:

1. Open Excel and go to the File tab.
2. Click on Open and then browse to the location of your corrupted file.
3. Select the file and click Open.
4. Excel will attempt to repair and recover the file.

    Example: Repairing and recovering an Excel file
    File tab -> Open -> Browse to file location -> Select file -> Open
