Learning how to write formulas is an important skill for any Excel user looking to develop their talents.
Content and Overview
This course was designed for anybody who needs to be able to confidently work with formulas in Excel. It is suitable both for complete beginners who want to start from the basics, and for those that have some experience but want to take things further.
The course is broken into different sections. It starts with building an understanding of the different elements of a formula, what the various symbols mean, some basic functions and different techniques for referencing cells.
Each section then focuses on a specific function category such as date or lookup functions. It starts to take things further by tackling mini projects and looking at more advanced formulas.
In over 80 lectures this course will teach you all the necessary skills to write advanced formulas with ease, and make those formula demons a thing of the past.
Working files are provided so that you can follow along and practice. You can also get assistance from myself with any queries you may have.
This first lesson includes;
This lesson is for formula beginners. It explains from the start how a formula is constructed and some 'need to know' formula facts.
The lessons covers;
When entering a formula in Excel you need to be aware of the order of calculation, and how to control it.
This lesson covers;
A common requirement of writing formulas in Excel is to calculate percentages. Examples include to calculate customer discounts, VAT, inflation and salesperson commission.
This lesson covers;
A function is a predefined formula in Excel, and Excel contains over 450 of them. Most formulas you write will include the use of functions so you need to be confident in using them.
This lesson includes;
An absolute cell reference is fully locked. When a formula is copied this reference does not change. It is often referred to as a fixed reference, or anchored reference.
This lesson covers;
A mixed reference is only partially fixed. There are two types of mixed reference; the row absolute and the column absolute.
This lesson covers;
Often your formula will need to reference cells on another sheet or entirely different workbook. You can create these references in the same way that you do when referencing cells on the same sheet.
However, it is a useful skills to be able to write and understand these references for when you use other user's spreadsheets.
This lesson covers;
The lesson explores the use of Defined Names on a spreadsheet. This practice can simplify the writing and understanding of formulas.
This lesson covers;
A range of cells can be converted into a table to make common Excel tasks easier. This technique is best applied to a large list such as a list of sales, employees, inventory or expenses.
What makes formatting a range as a table so useful with formulas, is that they provide dynamic and structured references. This can make formulas much easier to create and control over the long term.
This lesson covers;
Knowing how to use logical functions is a must if you want to be come proficient with formulas in Excel. The main logical function is IF.
This lesson covers;
An IF function can perform two possible actions upon the result of the logical test. These are known as value if true and value if false. If you need more alternative actions, then you may need more IF's.
This lesson covers;
An IF function can only perform one logical test, or condition. If you need to perform multiple conditions then you may need the AND or OR function. These are commonly combined with the IF function to perform actions based on multiple conditions.
This lesson covers;
Formulas will produce error values for many reasons. At times it may be that a value is not available to it yet.
If the error value does not indicate a problem with the formula and require solving, you may wish to perform an alternative action.
This lesson covers;
Create a running total to sum the year to date sales. This cumulative total will add the current months total onto the previous total.
This lesson covers;
Often the values to be summed will be dependent upon a specific condition. For example, you may wish to sum the sales totals only for a specific product, or for a specific region.
This lesson covers;
You can also perform tests against values in the criteria for the SUMIF function. An example of this could be to sum only the negative values in a range.
This lesson covers;
You can also use a formula to sum values in a list dependent upon multiple conditions. For example you could sum the sales values dependent upon the product and the region sold.
This lesson covers;
You may need to count the number of blank cells in a range. For this, you can use the COUNTBLANK function. This function will count all the empty cells in a range including empty strings generated by IF or IFERROR functions.
To count all the non-blank cells in a range, you need COUNTA. This function will count all the cells containing values, text and even logical values (TRUE and FALSE).
You may need to count the cells in a range that meet a specific condition. The COUNTIF function can be used for this.
This lesson covers;
To count cells in a range that meet multiple criterion, the COUNTIFS function can be used.
This lesson covers;
You may need to count the unique values in a range, but Excel does not have a function to do this.
This lesson covers;
When people refer to calculating the average, they are normally referring to the mean average. This is calculated by dividing the sum of a range of values by its count.
This process is simplified by using the AVERAGE function in Excel. Blank cells and cells containing text are excluded from the calculation.
The AVERAGEIF function can be used to calculate the mean average for a range of values that meet a single criterion.
This lesson covers;
The AVERAGE function despite excluding blank cells in a range will include any zeros in its calculation. To exclude zeros when calculating an average, the AVERAGEIF function be used.
This lessons covers;
You may need to calculate the average dependent upon multiple conditions.
This lesson covers;
The value that occurs most often in a range is known as the mode, or modal value. Excel has a MODE function to return the most frequently occurring value in a range.
This lesson covers;
The middle value in a range is known as the median. The MEDIAN function can be used to calculate this.
This lesson covers;
One potential problem when calculating averages are outliers. These are values that are much bigger, or much smaller than the other values in the range.
To prevent these outliers from having an impact on your average calculation, you could use TRIMMEAN.
This lesson covers;
The SUBTOTAL function performs subtotals on a list or database. This means you can perform functions such as sum, count and average while ignoring hidden rows.
This lesson covers;
The AGGREGATE function was introduced with Excel 2010 as an enhancement to SUBTOTAL. It can be used to perform aggregates such as sum, count and average, whist ignoring hidden rows or nested subtotals.
The key advantage to AGGREGATE over SUBTOTAL is that it can be used to ignore error values in a range when summing and counting.
This lesson covers;
The SUMPRODUCT function can be used to perform powerful array calculations. It can be used as an alternative to SUMIFS and COUNTIFS for complex summing and counting tasks.
This lesson covers;
It could be that the values you wish to sum are not in consecutive cells. For example, your list may be structured in a way that you want to sum every other row, or every 5th row.
This lesson covers;
Excel provides three useful functions for changing the case of text.
This lesson covers;
Erroneous spaces at the beginning and end of a text string can be a common cause for data analysis going wrong. Fortunately Excel provides a function to remove the erroneous spaces from cells.
This lesson covers;
You may wish to join the text from multiple cells into one cell. There are two ways to do this in Excel.
This lesson covers;
Extracting text from a string is a common use of text functions in Excel. This is the first of a few lessons performing various text extraction tasks.
This lesson covers;
Sometimes you will need to extract text from strings that have good structure and are reliable, and at other times they will be irregular.
This lesson covers;
A string can be different parts that are formed together such as 245-THAJ-013-1, where the hyphens are used to separate each part, however each part also has its own meaning.
This lesson covers;
Excel does not contain a function to count the number of words in a cell. Tasks such as analysing keyword data entered into search engines could be a reason to count how many words are in a cell.
This lesson covers;
If you are going to be writing formulas to perform calculations on dates, something you will often need to know is what the current date is. With the date changing daily, you need a function to always return the current date.
This lesson covers;
There are many reason that you may need to calculate the number of days between two dates. This could be to monitor the length of time between and order being placed and it being dispatched, or the time between an invoice being sent and it being paid.
This lesson covers;
It may be that you need to calculate the number of working days between two dates. Possible reasons to do this could be; to track invoice payments are made within a specified number of working days, or to calculate billable days on a task.
This lesson includes;
When calculating the difference between two dates, you may want to return the answer in years, months or both. Typical scenarios for this include calculating someone's age, or an employee's length of service.
This lesson covers;
You may need to add months onto a date to calculate a future date. Maybe to view the last date of a contract, or some other expiry date.
This lesson covers;
Excel contains a function to calculate a date a specified number of working days in the future, or in the past. This lesson looks at calculating a future date.
This lesson covers;
You may have a requirement to identify the day of the week for a specific date. This lesson looks at how to change the colour of all the cells in a list that contains a date which is a Sunday.
This lesson covers;
The DATE function can be used to convert data on a spreadsheet into a date format. It is also useful for entering dates into other formulas such as IF.
