Seeing “Excel cannot complete this task with available resources” can interrupt your work when opening a workbook, copying data, inserting rows, or running calculations. The error may be caused by limited memory, a large or complex workbook, problematic add-ins, or even file corruption.

Part 1: Why Does Excel Say “Cannot Complete This Task with Available Resources”?

The “Excel cannot complete this task with available resources” error usually appears when Excel does not have enough usable memory or processing resources to finish an action. It does not always mean your PC is low on RAM. Common cuases include:

  • Large or complex workbooks: Too many formulas, charts, PivotTables, images, or conditional formatting rules can overload Excel.
  • Insufficient available memory: Other running programs may consume the resources Excel needs.
  • 32-bit Excel limitations: The 32-bit version can access less memory and may struggle with large files.
  • Problematic add-ins: Excel or COM add-ins may consume extra resources or cause conflicts.
  • Damaged Excel files: If the error only happens with one workbook, the file itself may be corrupted.

Once you identify the likely cause, you can apply the appropriate fix below.

Part 2. How to Fix the ‘Excel Cannot Complete this Task with Available Resources’ Error (4 Easy Ways)

Method 1: Verify If You Are Surpassing Limits

When you see the message “Excel cannot complete this task with available resources,” you might want to consider whether or not your work is exceeding Excel’s inherent limitations.

Large datasets, extensive formulas, and resource-intensive macros, which do exactly that, tend to push Excel beyond its original capacity. The following ranges can explain this capacity:

  • The worksheet size limit is 1,048,576 rows x 16,384 columns.
  • A cell can contain, at most, 32,767 characters.
  • The maximum range in the calculation is 2,048.

Of course, these are just a few of the boundaries on Excel, but the real lesson is that the previous errors can appear if one overuses them.

To overcome this, you can optimize your spreadsheets by considering techniques like data summarization, pivot tables, or employing more efficient formulas.

Method 2: Close All Applications

If your computer system overloads, that can also contribute to the scarcity of resources that causes the “Excel cannot complete this task with available resources” error to pop up.

For this, though, the answer is quite simple. You must close all applications consuming system memory and resources, which will alleviate the strain on your system.

To do so, you must close all applications manually (by pressing the small cross on the top right corner of every application) or perform a clean boot.

Method 3: Ensure that Only One Instance of Excel Is Running

If more than one Excel workbook is open at a time, or something similar is in the works, the computer might consider that there is more than one ‘instance’ of Excel running, which can overload the system and cause an error.

To figure out the Excel cannot complete this task with available resources fix, all you need to do is follow these given steps:

  • Open Task Manager

    To pull open this, you can use one of the following ways:

    • Press CTRL + ALT + Delete. Click Start Task Manager.
    • Press CTRL + Shift + Esc.
    • Right-click an empty taskbar area, and then select Start Task Manager.
