Part 1: Causes and Symptoms of "Excel Running Slow"
"Why is my Excel running so slow?"
You might be wondering to know what the probable reasons behind Excel processing slow are and so, here are all the major causes of Excel running very slow.
Causes of Excel Running Slow
1. Invalid names in Name Manager
Excel’s "Name Manager" helps manage named ranges, but as your worksheets grow, unresolved names can slow things down. To fix this, simply go to the Name Manager and remove any invalid names. names.
2. Excessive Volatile Functions
Excessive use of volatile functions like VLOOKUP can slow down Excel, particularly when working with large datasets. This is why many businesses avoid these functions for big data.
3. Unresolved Formulas
Another reason for Excel lagging is Unresolved Formulas. So, if you have a sheet in your Excel whose cell has a value>0, then it means a cell has unresolved formulas. And that can also be the reason why you have encountered this problem.
4. Column References
Sometimes, not giving the optimizing column references can also slow down the performance of Excel. You need to optimize references. It is recommended to minimize the number of cells you are referencing in your Excel worksheet.
Moreover, if you are using a formula like VLOOKUP that has to look at million records, then it will certainly slow down your Excel performance. Thus, it is also recommended not to use a formula that needs to look at a lot of records. Otherwise, you will face a slow performance issue in Excel.
5. Too big spreadsheet
Are you having a too-big spreadsheet in your Microsoft Excel? If your answer is yes, then it is also one of the reasons behind Excel working slowly. Many users have a bad habit of storing a lot of data in one sheet. Moreover, if you are using volatile functions along with too big spreadsheets, then it will slow down your Excel performance. Thus, in this scenario, all you have to do is reduce the file size in Excel to come out of this problem.
6. Automatic Formula Calculation
Automatic Formula Calculation is also the cause of Excel lagging. In the case of automatic calculation, formulas are recalculated whenever you make any change. This sometimes makes Excel slow and that's why it is recommended to enable manual calculation.
Now, let's explore what can be the symptoms of Excel very slow, and below, we have listed every possible sign of the problem. Just check if your MS Excel has the following symptoms.
Symptoms of Excel Running Slow
1. Excel processing slow
The first and most common sign of Excel slowness issue is that it is processing slowly. It is taking too much time to process the operations you are doing in your Excel sheet. The reasons why your Excel processing is slow can be because of Array formulas or volatile functions you are using.
2. Excel slow calculating
Another symptom of Excel running slow and freezing is there is a performance issue in doing the calculation. Poor calculation speed further affects productivity and enhances user error. The reasons why your Excel is calculating formulas slowly may be you are using volatile functions in excess or not keeping all referenced data in one sheet. So, avoid volatile functions to get rid of Excel's slow calculating problem.
3. Excel is slow to open files
If your Excel is taking a very long time to open certain files, then it directly shows that your Excel is slow to respond and you need to do something to fix it. There can be many reasons why Excel slows to open files. First of all, it can be because you have stored a lot of data in one file or you have used too many volatile or complex functions in the Excel file.
4. System Memory
There is no doubt that Excel has enough capability to create big sheets, but as the sheet gets bigger, it requires more memory.

Otherwise, you will have to face performance complications issues.

You now are well familiar with the causes and symptoms of Excel running slow. Let's move towards its fixes to speed up Excel.
Solution 1: Keep the Spreadsheet Small
Too big spreadsheets in Excel can cause Excel file slow to respond because big Excel spreadsheets also take up large space on your system.
You also know that you need enough free storage space on your system so that you can do your task on the system smoothly and efficiently.

Solution 2: Enable Manual Calculation
Another solution to fix the problem is enabling the Manual Calculation mode in your Excel. When manual mode is turned on, Excel will not perform calculations until you don't press F9. The Automatic calculation mode will make Excel do calculations automatically and that can slow down the Excel speed to a great extent. Thus, the best thing you can do is turning on the Manual Calculation Mode. Below are the steps on how.
you can do it to fix the Excel working slow issue:
Step 1: To begin the process, choose "File" and then, "Excel Options" and then, the "Formulas" tab.
Step 2: After that, go to "Calculation Option" and then, select the "Manual" button under the "Workbook Calculation.
Step 3: Also, check the "Recalculate Workbook before saving" option if you like to make sure that the workbook calculation is always current. You can uncheck it if you want to calculate the formula using the F9 key before you exit.
Solution 3: Avoid Volatile Formula
As we told you earlier, volatile formulas are one of the reasons for this problem. So, the best thing is to get rid of the volatile formula to speed up your Excel. Some examples of volatile formulas are NOW, INDIRECT, OFFSET, etc. For instance, if you use the INDIRECT formula in a cell, and when you make any change, then the formula will also be recalculated.
So, the volatile functions take more processing speed, and then, you end up facing the slow Excel speed. Thus, avoid using the volatile formula or if you can't, then try to minimize its use.
Solution 4: Convert Formula to Value - change the unused formulas to static values:
Many formulas in Excel lead to its slow performance. Thus, if you have unused formulas in Excel, then it is better to change them to static values. There are many ways to convert unused formulas to static values in Excel. Here are shown using the Paste special method.
Step 1: Choose the cells you want to change formulas to values. After that, copy the cells using CTRL+C.
Step 2: Then, move to "Home">" Clipboard">" Paste">" Paste Special".
Solution 5: Clear Rules - avoid using the entire row/column as a reference (A: A)
When you reference the whole row or column as you think it consists of a few cells, Excel checks the reference row or column anyway. This takes a lot of time to do calculations and that ultimately slows down the Excel speed. Thus, if you want to fix the Excel processing slow, then you need to avoid using the entire row/column as a reference.
Solution 6: Reference Fewer Cells
A cell reference is used to determine a particular cell or cell range in the sheet. It can be used in function so that Excel can find the data easily you want in function to calculate. So, if you refer to a lot of cells, then it can affect the Excel performance. That's why it is always recommended that you should reference fewer cells so that Excel calculate formula or functions smoothly.
Solution 7: Repair Excel File
If Excel slows to open files, then you can repair Excel files to resolve the problem with ease. Luckily, there are a lot of third-party tools available that can help you to do this, one professional Excel repair software Wondershare Repairit - File Repair makes it easy for users to fix Excel errors and problems. By the way, you may also see another guide for Excel-related errors: Excel issue "out of memory".
Solution 8: Turn On Manual Calculation Mode
The Automatic Calculation will make your Excel run slowly when the program calculates new formula results automatically when a value or formula component changes. Therefore, turning on Manual Calculation mode to make Excel only recalculate when you force it to do so will speed up the Excel workbook and save time if you have a slow Excel spreadsheet.
Solution 9: Disable Uncessary Add-ins
The various add-ins in Excel are quite useful, but they can slow down your Excel files because adding an add-in means adding extra code to the Excel file. Therefore, it is possible to speed up Excel by disabling third-party add-ins (or if you have enabled some of Excel's built-in add-ins), although you can still keep them and enable them if you need them in the future.
Here are the steps that Disable uncessary Add-ins.
