How To Auto Generate Unique ID In Excel
Overview
Generating unique IDs in Excel is a common task for organizing and tracking data efficiently. Excel users often require a systematic approach to create these identifiers, which can be crucial for managing large datasets.
This guide provides clear, step-by-step instructions on how to auto-generate unique IDs using Excel functions. However, we will also explore why using Sourcetable might offer a more straightforward solution for this task than Excel.
Auto Generate Unique ID in Excel
Using GUID for Unique IDs
To generate a unique ID for each new row in an Excel Hazard Log, one solution is to use a GUID, which is an automatically recalculating unique identifier. However, GUIDs are not user-friendly due to their complex structure.
Creating Unique Identifiers with CONCAT
An alternative method is to use the CONCAT function across all columns to create a unique identifier. This approach combines values from multiple columns to ensure each ID is distinct.
Utilizing VBA/Macro for Automation
For advanced users, implementing a VBA macro can provide a customized solution to generate unique IDs automatically within Excel, tailored to the specific requirements of the Hazard Log.
Excel Formula for Unique ID Generation
The Excel formula =ARRAYFORMULA(IF(A:A="", "", TEXT(A:A, "yymm.") & CHAR(65 + INT((ROW(A:A)-1)/9999)) & TEXT(MOD(ROW(A:A)-1, 9999)+1, "0000"))) leverages the ARRAYFORMULA and IF functions to apply a unique ID generation across an entire column, using a timestamp and alphanumeric sequence.
Beginner-Friendly COLUMN Function
For Excel beginners, the COLUMN function can be combined with other functions to manipulate data and automate tasks, such as creating unique identifiers in a more accessible manner.
