2. Move the mouse cursor to the fill handle (the small black square) at the bottom right corner of the selection
3. Drag the fill handle in the desired direction to fill the adjacent cells with the same pattern (e.g., a series of numbers, months, or weekdays)
4. Release the mouse button when you reach the desired range (you can also double-click the fill handle to autofill until the end of the data range)
5. Customize the autofill options if needed by clicking on the Autofill Options button that appears after autofilling (e.g., fill with formatting only, fill with series, or copy cells)

Here is an example of autofilling a series of numbers using the fill handle:

As you can see, autofilling in Excel is very straightforward. However, there are some tips and tricks that you should keep in mind to optimize your autofilling experience and avoid common mistakes.

Top 3 Time-Saving Autofill Techniques in Microsoft Excel

If you want to go beyond the basics of autofilling in Excel and improve your productivity even further, you can try some advanced techniques that can save you a lot of time and effort. Here are the top 3 time-saving autofill techniques in Excel:

1. Flash Fill: a powerful feature that automatically fills in data based on patterns or rules that you specify. For example, you can extract the first name or last name from a list of full names, merge columns, split cells, or format dates in a custom way. To use Flash Fill, you need to start typing the desired result in the adjacent cell(s) and press Enter or Ctrl + E. Excel will automatically detect the pattern and apply it to the data range. Here is an example of using Flash Fill to split a column of full names into first names and last names:



2. Dragging non-adjacent cells: a useful technique that allows you to autofill in non-adjacent cells or ranges without manually dragging the fill handle. To do this, you need to select the source cells, hold down the Ctrl key, and drag the fill handle to the target cells. Excel will automatically fill in the values or patterns based on the selected cells, even if they are not adjacent. Here is an example of dragging non-adjacent cells to autofill weekdays:



3. Filling weekdays, months, and years: a handy technique that allows you to autofill in a sequence of weekdays, months, or years without manually typing them. To do this, you need to start typing the first value in the series (e.g., Monday), select the range of cells you want to fill, and drag the fill handle in the desired direction while holding down the Ctrl key. Excel will automatically fill in the weekdays, months, or years based on the first value. Here is an example of autofilling weekdays using the Ctrl key:

As you can see, these advanced autofilling techniques in Excel can save you a lot of time and effort, especially when dealing with large data sets or complex tasks. However, there are even more tips and tricks that you can use to become an Excel autofilling master.

Master Excel Autofilling with These 7 Tips and Tricks

If you want to take your Excel autofilling skills to the next level and become a power user, you can try these 7 tips and tricks:

1. Using formulas and functions to create custom series: a versatile technique that allows you to create custom series of data based on complex formulas or functions. For example, you can use the LINEST function to generate a trendline or regression analysis, or the IF function to apply conditional logic. To use this technique, you need to enter the formula or function in the first cell of the series, select the range of cells you want to fill, and drag the fill handle in the desired direction. Excel will automatically fill in the series based on the formula or function. Here is an example of using the LINEST function to create a trendline:



2. Copying entire rows and columns: a quick way to autofill an entire row or column based on the adjacent data. To do this, you need to select the row or column you want to fill, move the mouse cursor to the fill handle (either on the top or left edge of the selection), and drag it to the desired range. Excel will automatically fill in the values or patterns based on the adjacent data. Here is an example of copying a row in Excel:



3. Working with auto-complete lists: a useful feature that allows you to fill in a series of values based on previously entered data. To do this, you need to start typing the first few characters of the desired value in the target cell, and press Enter or Tab when Excel suggests the correct value. This technique can save you time and reduce errors when working with repetitive data. Here is an example of using auto-complete with a custom list:



4. Using absolute references: a technique that allows you to lock the reference of a cell or a range in a formula or function, so that it does not change when autofilling. To do this, you need to add a dollar sign ($) before the row number or the column letter of the reference. For example, if you want to autofill a formula that refers to cell A1 and B1, but you want to keep the reference to A1 fixed, you need to write $A$1 instead of A1 in the formula. Here is an example of using absolute references in a formula:



5. Filling empty cells with data from neighboring cells: a technique that allows you to fill in empty cells with values from adjacent cells. To do this, you need to select the range of cells you want to fill, click on the Ctrl + G shortcut to open the Go To dialog box, select the Blanks option and click OK. Excel will select all the empty cells in the range. Then, you need to type = (equal sign), click on the cell that contains the adjacent data, and press Ctrl + Enter. Excel will automatically fill in the empty cells with the adjacent data. Here is an example of filling empty cells in Excel:



6. Creating custom lists for autofilling purposes: a technique that allows you to create your own custom lists of data for autofilling in Excel. For example, you can create a list of company names, job titles, or product SKUs, and use it to quickly fill in repetitive data. To do this, you need to go to the File menu, click on Options, select the Advanced tab, and scroll down to the General section. Then, you need to click on the Edit Custom Lists button, type in the list values (one per line) and click Import or OK. Here is an example of creating a custom list in Excel:



7. Protecting cells when autofilling: a technique that allows you to prevent Excel from overwriting locked cells or formulas when autofilling. To do this, you need to select the range of cells you want to protect, go to the Home menu, click on the Format Cells button, select the Protection tab, and check the Locked option. Then, you need to go to the Review menu, click on the Protect Sheet button, and enter a password or leave it blank (if you don’t want to lock the sheet). Here is an example of protecting cells in Excel:

These tips and tricks can help you become much more efficient and productive in Excel, especially if you work with large and complex data sets. However, if you work in a specific field like finance and accounting, there are some practical applications of autofilling that you should be aware of.

Automating Data Entry with Autofill in Excel: Best Practices for Professionals

Excel is a popular tool for data entry tasks in various industries, from finance and accounting to marketing and research. However, data entry can be very time-consuming and error-prone, especially if you need to enter the same data repeatedly. Autofilling in Excel can help you automate many data entry tasks and ensure accuracy, as long as you follow some best practices. Here are some practical tips for using autofilling in Excel for data entry:

1. Avoid blank cells: when entering data manually, make sure to fill in all the cells in the range, even if they contain zero or NA. This will help Excel detect the correct pattern or logic when autofilling.
2. Use absolute references: when referencing cells in formulas or functions that are used for autofilling, use absolute references to lock the references and avoid errors. For example, if you want to calculate the total price of a product based on the quantity and the unit price, you can use the formula =B2*$C$1 and autofill it down to the entire data range. This will ensure that the reference to C1 (the unit price) does not change when autofilling.
3. Protect cells and formulas: when autofilling in a shared workbook or a collaborative environment, make sure to protect sensitive cells or formulas by using password protection or permissions. This will prevent other users from overwriting or editing your data.
