Excel Cannot Complete this Task with Available Resources

The “Excel cannot complete this task with available resources” error usually happens when Excel runs out of system memory or other resources needed to perform an action. Here’s what you can do to fix or work around this issue:

Common Causes

• Large or complex workbook (many formulas, links, data)
• Insufficient RAM or CPU resources on your computer
• Too many add-ins or background programs running
• Corrupted Excel file or installation

 

How to Fix It

1. Close other programs:
Free up system resources by closing all unnecessary apps, especially memory-heavy ones.

2. Reduce file size:

• Remove unused worksheets, formulas, or formatting.
• Convert complex formulas to values where possible.
• Avoid volatile functions like INDIRECT, OFFSET, NOW, TODAY.

3. Disable add-ins:

• Go to File > Options > Add-ins
• Select COM Add-ins and click Go
• Uncheck add-ins and restart Excel.

4. Increase virtual memory (paging file):

• On Windows, increase your paging file size via System Properties > Advanced system settings > Performance > Settings > Advanced > Virtual memory.

5. Check for file corruption:

• Open a new workbook and try copying data in smaller chunks.
• Use Open and Repair from the File menu.

6. Update or repair Excel:

• Make sure Excel is updated to the latest version.
• Use Office Repair via Control Panel > Programs and Features > Microsoft Office > Change > Repair.

7. Use 64-bit Excel:

• If you work with very large files regularly, 64-bit Excel can use more RAM than 32-bit.

 

Preventive Tips

• Break large workbooks into smaller files.
• Avoid excessive conditional formatting and complex formulas.
• Save work regularly to avoid data loss.

 SOLVED - Excel Cannot Complete this Task with Available Resources...

 

So, you have a massive 45MB Excel spreadsheet open with multiple pages and you're about to update a few thousand cells

when this error box pops up: "Excel cannot continue this task with available resources. Choose less data or close other

applications. Continue without Undo?" What to do?! This can be a frustrating experience, especially if you're certain the

computer is powerful enough and has 4GB or more RAM installed. The issue is indeed resources related, but adding more

memory will not fix things. If for example you have Chrome or Firefox open with a couple dozen tabs at the same time,

closing that browser while working in Excel can help alleviate the resource limitation... but not always.

A http://how-to-install-it.blogspot.com reader who uses Microsoft Office Home and Business 2013 recently wrote in for help

with this problem . Here's the permanent way to solve the "Excel Cannot Complete Task with Available Resources" error.

 

How to Fix: Excel Cannot Complete Task with Available Resources Error

 

To begin with, confirm you are running the 64-bit version of Microsoft Windows 7 or 8 operating system. Next launch Excel,

then open up 'Task Manager' (right click on taskbar > Start Task manager) and navigate to the 'Processes' tab. You should

see "Excel.exe *32" listed. If that's the case, the reason Excel is crapping out when you work with large .xlsx

spreadsheets is because 32-bit Excel is installed and 32-bit Excel can only address 2GB of system RAM. Excel needs more

system resources, but for that you MUST install the 64-bit version of Microsoft Office.

 

To do that, uninstall Office 2013 and reinstall the 64-bit version of Office 2013. This is easily done from the 'Office

Home and Business 2013' disk by 1) CANCELLING the setup.exe program which immediately loads and then 2) navigating on the

Office disk to the folder '/office' and double clicking on 'setup64.exe'. This will force Office 2013 to install the 64-

bit version -- the default installer loads the x32 version of Office which is compatible with both x32 and x64 operating

systems.

 

That's it! With the 64-bit version of Microsoft Office Home and Business 2013 installed Excel will address as much memory

as is installed & available to applications. This http://how-to-install-it.blogspot.com  can be applied to Office 2010

which also comes in x32/x64 flavours. If you want to confirm you've installed the x64 version of Office 2013, launch

Excel, then open up 'Task Manager' (right click on taskbar > Start Task manager) and navigate to the 'Processes' tab. You

will now see "Excel.exe" listed, which means a native x64 application is running in the x64 version of Windows 7/8

operating system.
