Creating a unique ID in Google Sheets is a crucial task for many users, especially those who work with large datasets or need to identify specific records.

In this blog post, we will explore the different methods to create a unique ID in Google Sheets, including formulas, add-ons, and scripts.

Why Create a Unique ID in Google Sheets?

A unique ID, also known as a primary key, is a column in a database table that uniquely identifies each record. In Google Sheets, a unique ID can be used to identify each row in a table. This is particularly useful when working with large datasets or when you need to track changes to specific records.

Here are some reasons why you might want to create a unique ID in Google Sheets:

  • To quickly locate a specific record
  • To track changes to specific records
  • To merge data from multiple sheets
  • To create a unique identifier for each record

Method 1: Using a Formula

One way to create a unique ID in Google Sheets is by using a formula. You can use the following formula to create a unique ID:

=TEXT(A1,”YYYYMMDD”)&”_”&TEXT(ROW(A1),”000000″)

This formula combines the current date and time with the row number to create a unique ID. The & symbol is used to concatenate the two parts of the formula.
