How to Reduce Excel File Size

If you work with Microsoft Excel on a regular basis, you may have noticed that some of your files tend to get quite large. This can be a problem when it comes to sharing or emailing them, especially if the recipient has a slow internet connection. Fortunately, there are several ways to reduce the file size of your Excel spreadsheets. In this blog post, we’ll walk you through some simple steps you can take to reduce the size of your Excel files.

Introduction

Microsoft Excel is one of the most popular tools for data analysis and manipulation. However, as much as it can be useful, it can also be frustrating, especially when it comes to file size. It’s not uncommon for an Excel spreadsheet to grow to hundreds of megabytes, making it challenging to share or store. In this blog post, we’ll be sharing some tips on how to reduce the file size of your Excel spreadsheets.

1. Use the ‘Save As’ function

Did you know that every time you save an Excel file, the size may increase? This is because Excel saves a copy of the file each time you save it. You can use the ‘Save As’ function to save a copy of the file with a new name. This will reduce the file size and ensure that you have a backup of your original file. To use this function, go to the File menu, select ‘Save As,’ and choose a new name for your file.

2. Remove unnecessary formatting and objects

Another way to reduce the file size of your Excel spreadsheet is to remove any unnecessary formatting and objects, such as images, charts, or tables. These elements can take up a lot of space, especially if you have multiple copies of the same chart or image. To remove them, select the object, right-click, and choose ‘Delete.’

3. Compress images

If you have images in your Excel spreadsheet, you can reduce their file size by compressing them. To do this, select the image, go to the ‘Picture Tools’ tab, and choose ‘Compress Pictures.’ You can choose the resolution you want, and Excel will compress the image to fit that resolution. Note that this may reduce the quality of the image slightly, so make sure to preview the image before compressing it.

4. Delete unused worksheets

Unused worksheets can contribute to the file size of your Excel spreadsheet, even if they’re empty. To delete them, right-click on the tab of the worksheet you want to delete and choose ‘Delete.’

5. Use the ‘Clear Contents’ function

If you have data that isn’t needed, you can use the ‘Clear Contents’ function to remove it. This will ensure that the data is removed entirely, and the file size is reduced. To use this function, select the cell or range of cells you want to clear, go to the ‘Home’ tab, and click ‘Clear’ in the ‘Editing’ group. Choose ‘Clear Contents’ from the dropdown menu.

Reducing the file size of your Excel spreadsheet is essential, especially if you need to share it or store it. The tips we’ve provided in this blog post are simple and easy to implement, and they’ll help you reduce the file size of your Excel spreadsheet significantly.

6. Use Excel’s ‘Optimize Compatibility’ option

Excel has a feature that allows you to optimize your file for a specific version of Excel. This can help reduce the file size since older versions of Excel may not support some of the newer features that you’re using in your file. To use this feature, go to the File menu and select ‘Save As.’ Click on the ‘Tools’ dropdown menu and choose ‘General options.’ Check the box next to ‘Optimize Compatibility’ and choose the version of Excel you want to optimize the file for.

7. Use external data sources

If you have a lot of data in your Excel file, it can contribute to the file size. One way to reduce the file size is to use external data sources. This means that you store your data in a separate file and link to it from your Excel file. This can help reduce the file size since your Excel file will only contain links to the data, not the data itself. To do this, go to the Data tab, select ‘From Other Sources,’ and choose the type of data source you want to use.

8. Enable workbook compression

Another way to reduce the file size of your Excel spreadsheet is to enable workbook compression. This is a feature that compresses your file when you save it, reducing the file size. To enable workbook compression, go to the File tab, select ‘Options,’ and choose ‘Advanced.’ Scroll down to the ‘General’ section and check the box next to ‘Compress Workbook On Save.’

9. Save files in Binary format

Excel files are typically saved in the .xlsx format. However, you can also save them in binary format (.xlsb). This format can help reduce the file size since it compresses the file and removes some of the unnecessary data. To save your file in binary format, go to the File tab, select ‘Save As,’ and choose ‘Excel Binary Workbook’ from the ‘Save as type’ dropdown menu.

Reducing the file size of your Excel spreadsheet can help make it easier to store and share. The tips we’ve provided in this article are straightforward and easy to implement, and they can help you reduce the file size of your Excel file significantly. Try them out, and see how they work for you.
