Are you tired of manually entering complex calculations in Excel? Look no further! This article will help you discover simple ways to force Excel to do the hard work for you.

### Getting Familiar with Manual Calculation

Manual calculation in Excel requires you to disable auto-formulas and compute each cell individually. This gives greater control over calculations, especially when dealing with large data sets or complex equations. Here’s how to get acquainted with manual calculation:

1. Open an Excel workbook and go to the Formulas tab. Select Calculation Options and choose Manual from the drop-down list. Or, press F9 to enter manual calculation mode.
2. Create a basic arithmetic formula in any cell. Select the cell and press Enter. The formula will not calculate automatically, instead it will show the text of the formula in the cell. To update the result of this formula, press F9.
3. Copy and paste the formula into other cells, or rerun it after changing data values in other cells. After making changes to cells having data values used in the calculations, the edits will only show their effect after pressing F9 manually.

Manual calculations are not as common as they used to be before computers, but there are times when precision matters, like when engineers at NASA design spaceships.

Knowing when to use manual calculation is important. Now that you know how it works, you can determine when manual calculation is best for your spreadsheet.

### Determining When to use Manual Calculation

When to use manual calculation in Excel is an important decision. Here are six steps to help decide if it’s time for the switch.

1. Consider the size and complexity of the workbook. If it has a lot of data or formulas, manual calculation could be beneficial.
2. Think about the speed of your computer. If it’s slow, then manually calculating will save time and boost performance.
3. Look at how often the workbook changes. If updates are frequent, then manually calculating saves time as Excel recalculates all formulas upon change.
4. Determine if you need more control over formula recalculation timings.
5. Identify if workbook uses heavy and complex formulas like nesting multiple IF functions, which makes recalculation slow.
6. Evaluate if automatic creation of pivot tables can cause performance bottlenecks on large datasets.

If any of the above indicators apply, consider switching to manual calculation. This feature can lower processing overheads and keep better control over dependencies between formulas, as well as tracking errors. Know how to customize settings for manual calculation to make the most of this function.

### Identifying Circular References

To find circular references in Excel, do these 3 steps:

1. Go to the “Formulas” tab in the ribbon menu.
2. Click on “Error Checking.”
3. Select “Circular References” from the drop-down list.

This will show you cells that refer back to themselves. This can cause incorrect calculations and mess up your workbook’s performance. You may need to edit these cells to fix the circular reference issues.

It is important to notice and solve circular references right away. This is to stop further errors in your workbook. To make sure accuracy and dependability, it is very important to watch out for circular references and quickly fix them.

In some cases, a circular reference can be intentional. For example, if you use a formula that needs many iterations before giving correct results, a circular reference may be needed. However, usually it is better to stay away from this as it can cause misunderstanding and make it hard for other people to understand or change your work.

Checking for Hidden Rows and Columns

Finally, you should check for hidden rows and columns. These can also cause troubles with manual calculations in Excel.

### Checking for Hidden Rows and Columns

Have you checked for hidden rows and columns while troubleshooting manual calculation issues on Excel? This step is very important for accurate results. Here is a 5-step guide to help you out:

1. Select the entire worksheet by clicking the triangle at the top left corner.
2. Right-click on any row number or column letter.
3. Select “Unhide” from the dropdown menu.
4. Repeat steps 2-3 for both rows and columns, checking each one carefully.
5. Save your workbook before recalculating.

Checking for hidden rows and columns is key when dealing with manual calculations on Excel. It may contain data that affects other cells. So, take a few extra minutes to check for hidden rows and columns for accurate results.

My colleague once had an issue with manual calculations on an Excel sheet. They spent hours trying to figure out why their numbers weren’t adding up correctly. Later, they found out there were several hidden rows containing crucial information that needed to be included in their calculations. A simple oversight, but it could have been avoided if they had checked for hidden rows earlier on.

Navigate to the Data tab in the ribbon and select Edit Links. This will open a box with details of all external links in your workbook. Source file location, type, status and update info of each link are shown.

Identify broken links by looking out for error messages at the bottom. A common message could be “The source currently has missing or inaccessible components“.

Resolve broken links by selecting & editing them. Press \’Change Source\’ or \’Open Source\’ to redirect Excel to the right accessible files.

Analyze any named ranges in formulas which are linked externally, using similar options.

Identify risks associated with external links connected over the Internet, such as security breaches or malfunctions.

For updates, be selective about connections as too many remote sources can cause slow refreshing & eventually lead to crashes.

Pro Tip- Import data into Excel instead of relying on various sources!
