How to Fill Series in Google Sheets – Quick Auto-Fill Guide

In this document, we will guide the process of how to fill series in Sheets.
This process involves opening a spreadsheet, entering values, and using Google Sheets' features to manage data efficiently.

Want to quickly generate a list of numbers, dates, or even text patterns like months? Google Sheets makes it easy with its built-in Autofill feature. All you need to do is provide a starting pattern, and Sheets will handle the rest.

Step-by-Step Guide to Fill a Series

1. Enter the Starting Values
   Begin by typing at least two consecutive values into adjacent cells. These can be:

   • Numbers: 1, 2

   • Dates: 01/01/2024, 01/02/2024

   • Text patterns: Jan, Feb

2. Select the Cells
   Click and drag to highlight the cells that contain your starting values.

3. Use the Fill Handle
   Move your cursor to the small blue square in the bottom right corner of the selection.
   Your cursor will change to a plus sign (+).

   • Click and drag down or across to extend the series.

   • Google Sheets will auto-detect the pattern and continue it in the new cells.

4. Customize the Fill (Optional)
   After dragging the fill handle, right-click on it to see additional options:

   • Fill weekdays only

   • Fill months or years

   • Create custom increments (e.g., every 5 numbers)

Pro Tips for Filling Series In Google Sheets

1. Use auto-fill smartly – Dragging the fill handle while holding Ctrl (Windows) or Option (Mac) can generate custom sequences instead of repeating values.

2. Leverage ARRAYFORMULA for automation – Use ARRAYFORMULA with SEQUENCE to auto-generate number series dynamically without manual dragging.

3. Use double-click for faster filling – Instead of dragging, double-clicking the fill handle automatically extends the series down to the last adjacent filled cell.

Common pitfalls and how to avoid them

1. Incorrect data selection – If the first two values are not in a logical sequence, Google Sheets may not recognize the pattern correctly.

2. Forgetting absolute references in formulas – Using a dynamic reference instead of $A$1 in formulas may break the sequence when copying down.

3. Dragging instead of using built-in functions – Manually dragging large datasets can be inefficient; use SEQUENCE() for a structured approach.
