What is the Excel File Size Limit?

Before knowing anything, let’s understand Excel’s built-in limits:

  • Maximum rows: 1,048,576
  • Maximum columns: 16,384 (XFD)
  • Maximum file size: Depends on system memory and version
  • Maximum worksheets: Limited by available memory

So, technically, you can’t increase the size, but you can optimize your file for more storage space.

Why Large Excel Files Become a Problem?

Users face multiple issues due to a large Excel sheet:

  • Slow opening and saving data files.
  • Your application frequently crashes and freezes.
  • High memory (RAM) consumption
  • High risk of file corruption.

How to Improve Excel Performance with Large Files Manually?

Handling large Excel sheets is not an easy task for any user, so you can optimize the file by deleting unwanted data or formatting, or following other techniques like:

  • Optimizing Formulas
  • Deleting Unwanted Data
  • Compress Excel File Size by Zipping

  4. Browse the path and save your file.

Method 2: Removing Unnecessary Formatting to Handle Large Excel File

  1. Open your Excel file.
  2. Use “Ctrl + End” to check the last cell.
  3. If it goes beyond your actual data, then it means there’s hidden formatting.
  4. Choose all your empty rows below your data.
  5. Right-click and choose the “Delete” icon.
  6. Now follow the same steps for columns.
  7. And save your file.

3 Method: Optimizing Formulas

  1. Select all your Cells and formulas.
  2. Choose “Ctrl + C” to copy data.
  3. Right-click and “Paste Special”“Values”.

Method 4: Increase Excel File Size by Deleting Unwanted Data

Empty rows/columns and unwanted data take up more storage space in the Excel file, which makes it large and hard to handle. So, try to remove them to increase Excel file size by following the given steps:

  1. Select rows and columns.
  2. Right-click and choose the “Delete” icon.
  3. And save your file.
  4. Now repeat the same process for unwanted data as well.

Method 5: Compress Size by Zipping

If you have multiple large files and don’t want to use them for a long time, then Zipping would be the best option to decrease Excel file size.

  1. Locate the path of your file.
  2. Right-click on it, choose the “Compress To” option.
  3. And select the “Zip” option.
  4. And successfully your file is compressed.

Method 6: Cleaning Hidden Data

Sometimes hidden data becomes a cause of a large Excel sheet.

  1. Choose your whole sheet.
  2. Right-click and select the “Unhide” option.
  3. And delete the wanted data, rows, and columns.
