## Excel Formulas Overview

Frequent Excel users know that formulas are great! They make doing complex calculations simple. We’ll cover the basics here: what formulas are, the terms used, and the most popular ones. Then, you’ll have a better idea of how to use them for managing and analyzing data. After this section, you’ll be an Excel formula pro!

### Understanding the Basics of Excel Formulas

If you’re a novice to Excel, formulas can be a bit tricky. But, grasping the fundamentals of Excel formulas will make them easier to handle. Formulas in Excel are used to calculate information and can save time and improve efficiency when working with lots of data.

Here’s a 5-step guide to get you started on the basics of Excel formulas:

1. All formulas must begin with an equal sign (=).
2. Use additions (+), subtractions (-), multiplications (*) and divisions (/) for basic math.
3. Parentheses are used for nested functions or expressions.
4. Functions (like SUM or AVERAGE) are built-in presets that do calculations.
5. You must reference cells in formulas to avoid errors and to make updating values simpler.

It’s also important to be familiar with common terminology. For instance, a cell reference is the cell’s location, identified by its row and column letter (e.g., A1, B2). The outcome will be in the cell where you entered the formula. Relative referencing is when related data is copied down when inserting or deleting.

Microsoft’s program code includes roughly 450 functions. Knowing these functions means you can do complex tasks quicker, like forecasting profits, finding duplicate values and studying trends – which would take longer to do manually.

We can now identify the most common formulas including SUM, AVERAGE and COUNT. These are the foundations of more complicated calculations which require more functions in Excel.

### Identifying the Most Commonly Used Formulas

To identify the most commonly used formulas, first you have to find out which cells contain formulas. This can be done by scanning your worksheet for cells with values not typed in manually, but having a formula bar above them.

Then, sort and filter these identified cells to determine which of them are used most frequently across different sheets or workbooks.

To make this task easier, use different formula auditing tools such as trace precedents/dependents or evaluating formulas to establish which functions represent the most used formulas in the identified cells.

List out all the commonly-used functions and arrange them based on their frequency of use. This will help you gain some valuable insights into how Excel performs calculations.

Identifying these most commonly used formulas will help save time as you don’t need to look up the same formula repeatedly. Also, you can prioritize learning which functions would bring more value to you based on their popularity.

Studies show that learning common Excel formulas increases overall job performance by 21%, according to The Muse.

Lastly, let’s look at how to lock Excel formulas to avoid accidental tampering and preserve data integrity.

## Locking Excel Formulas

When working with formulas in Excel, it’s essential to protect them from changes. In this part, we’ll discuss how to do this. We’ll cover 3 sections.

1. Enable the ‘Formula Auditing’ feature. It’s a built-in Excel feature that tracks changes to formulas.
2. Next, I’ll show you how to create a password-protected macro. This is powerful for keeping formulas safe.
3. Finally, we’ll look at best practices for locking cells with formulas. This will keep your data secure.

Let’s get started protecting our data in Excel!

### How to Lock Formulas in Excel: Enabling ‘Formula Auditing’ Feature

Enabling ‘Formula Auditing’ in Excel is a must for locking formulas. It makes understanding the formula structure a breeze and helps spot which cells have formulas and which don’t. Here’s a 5-step guide:

1. Open Excel.
2. Go to the ‘Formulas’ tab.
3. Choose ‘Show Formulas’ from the dropdown next to ‘Formula Auditing’.
4. Select cells containing formulas & press ‘Ctrl + 1’.
5. Check the ‘Locked’ box on the ‘Protection’ tab.

Once locked, the cells can only be edited with explicit permission, which is great for safeguarding data in spreadsheets.

We’ve discussed Formula Auditing – now let’s move to other methods of locking Excel formulas. Data security should always be a priority, so use these methods to protect your documents. Don’t wait – act now!

Finally, learn how to create a password-protected macro to restrict access to confidential workbooks. A Step-by-Step Guide on Creating a Password-Protected Macro will help users do just that.

### A Step-by-Step Guide on Creating a Password-Protected Macro

Creating password-protected macros is essential in today’s business world to help prevent any financial or other losses due to fraud or unauthorized access. Here’s a five-step guide to simplify the process:

1. Open the Excel document and press Alt+F11.
2. Right-click the project name in the Project Explorer Window to create a new module.
3. Feed in code that will run each time an incorrect password is entered.
4. Add one more layer of security using passwords and hiding sheets.
5. Finally, save the workbook with Macro-enabled mode.

Locking cells containing formulas is also important, but may be daunting for some who are new to Excel or don’t feel comfortable with security features. Here’s the best practices guide to help!

### Locking Cells Containing Formulas: Best Practices

Locking cells containing formulas in Excel is essential for avoiding accidental changes. Follow these 3 simple steps for locking such cells:

1. Select the formula-containing cell or range.
2. Click “Format Cells” under the “Home” tab.
3. In the “Protection” tab, select “Locked”. Then, click “OK”.

These steps will ensure that accidental changes won’t occur. Plus, you can create a password to protect sensitive data in your Excel Worksheet.

It’s best to use relative references instead of absolute references with dollar signs when locking cells containing formulas. Relative references will adjust when the formula is copied and pasted into another cell. Absolute references with dollar signs won’t change.

Pro Tip: Before setting up protection options, make sure all formatting, like visible rows/columns and colors, is in place. Otherwise, problems may occur while navigating protected files.

Now that we know how to lock cells containing formulas, let’s move on to protecting Excel formulas!

## Protecting Excel Formulas

I’m an Excel user, so I know the value of keeping sensitive data and formulas secure. That’s why I’m going to provide some advice on protecting those formulas. By doing this, you can make sure that no unauthorized changes or accidental overwrites happen.

We’ll go over the various ways to guard Excel formulas, like enabling worksheet protection and only allowing certain users to edit. Furthermore, we’ll look at how to hide formulas in Excel, so you can still show the required data while your calculations are kept safe.

### Excel Formulas Protection: Enabling Worksheet Protection

First step to protecting your Excel formulas: enabling worksheet protection! Here’s a guide for making it easy:

1. Go to the Review tab on the Excel Ribbon. In the Changes group, click Protect Sheet.
2. In the Protect Sheet dialog box, choose the options you want – like locking specific cells or stopping users from formatting cells.
3. If needed, enter a password to stop people from unprotecting the sheet without permission.

Worksheet protection prevents others from changing cell contents or deleting formulas. It also saves you from making accidental changes that could be faulty or corrupt data.

When you protect your worksheets, you can share your workbook with confidence knowing it is secure. This has been crucial for businesses – from financial statements to HR records – for many years.

Recently, I read about a major company losing employee data because of an unprotected Excel file sent via email. Worksheet protection and other security measures like password-protected links can help protect against such risks.

Finally, our tutorial on allowing users to edit ranges – a great tool for collaboration in large groups – is coming soon!

### Allowing Users to Edit Ranges: A Step-by-Step Tutorial

To let users edit certain areas of your Excel sheet, do these steps:

1. Highlight the cells or range of cells you want to lock.
2. Go to the Review tab and press Allow Users To Edit Ranges.
3. In the Allow Users to Edit Ranges dialog box, choose New.
4. Choose the cells or range of cells the user can edit.
5. Press OK twice, then enter a password if needed in the Protect Sheet dialog box.

If a user tries to edit a cell outside the allowed range, they’ll get an error message saying they can’t change it.

It’s vital to remember that only allow users to edit ranges when you need to. Because it can affect the security of your data. E.g. if there’s sensitive info on your sheet, don’t let users edit any of it.

If you do give users access to editable ranges, make sure you trust them and limit their access. You can also make a separate sheet with limited access for some users.

Finally, we’ll look at how hiding Excel formulas can protect your data even more.

### Hide Excel Formulas: Protecting Your Data

Text:

Select the cell(s) with the formula you want to hide. Right-click and choose “Format Cells”. In the “Format Cells” dialog box, select “Custom” under the Category tab. Enter three semicolons (;;;) in the “Type” field and click OK.

This hides the formula that was visible in the cell(s) before. It protects sensitive information from snoopers. Companies must make sure only authorized personnel have access to confidential files when sharing.

Hiding Excel formulas has many benefits. It prevents accidental changes in important fields like tax calculations, thus avoiding legal issues.

Take Maria’s story as an example. She calculated taxes in her company’s finance department using Excel sheets. She accidentally shared her calculations with another team member. This person modified some numbers, causing substantial losses for their business. That’s how dangerous it can be when critical data gets into wrong hands.
