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.
