In this in-depth Excel tutorial, I'll walk you through the intricate process of auto-populating unique IDs and indexes in your Excel tables, revolutionizing your data management practices. With over 25 years of hands-on experience in Excel, I understand the significance of efficiency and accuracy in your daily tasks. Let's delve into actionable solutions that will transform your Excel workflow:
1. **Auto-populating Fixed References**: Say goodbye to manual entry errors by learning how to auto-populate fixed references in your Excel tables. By implementing simple formulas, such as using the "equals" sign followed by the desired reference within quotes (e.g., "= "Region 2"), you'll effortlessly propagate data across your spreadsheet. The benefit? Eliminate the risk of human error and save valuable time that would otherwise be spent on tedious copy-and-paste tasks.
2. **Generating Incremental Counts**: Explore multiple techniques for generating incremental counts or indexes in your Excel tables. Whether you opt for the ROWS function, ROW function, or OFFSET function, you'll unlock the power of dynamic numbering that adjusts seamlessly as you add new data. The advantage? Maintain data integrity and consistency without the hassle of manually updating formulas, ensuring accurate analyses and reporting.
3. **Utilizing Power Query for Data Management**: Harness the capabilities of Power Query to streamline your data management processes. By creating duplicate tables that retain original reference numbers, even after sorting or filtering data, you'll establish a robust foundation for analysis and reporting. The beauty of Power Query lies in its ability to automate repetitive tasks, allowing you to focus on deriving insights from your data. Benefit from enhanced efficiency, accuracy, and flexibility in data manipulation.
4. **Creating Auto-populating Unique IDs**: Master the art of generating auto-populating unique IDs for your Excel tables. Through a combination of functions such as DATE, CODE, LEN, and ROUND, you'll craft IDs that dynamically adapt to your data, minimizing duplicates and ensuring data integrity. By automating the ID generation process, you'll significantly reduce the risk of errors and streamline data entry tasks. Experience peace of mind knowing that your data is consistently structured and accurately represented.
Throughout this tutorial, I'll provide detailed examples, practical tips, and actionable advice to empower you to excel in Excel. Whether you're a novice or an experienced user, these techniques will elevate your proficiency and enable you to achieve tangible results in your data management endeavours.

Thanks back at you John 👍
I'd still / always be afraid of generating a non-unique "ID", which, of course, is no "ID" then. The first, formula and row based suggestions had the big advantage of being a running counter.
But to automate that, one would have to keep track of the highest actual ID, and raise it by 1 on data row entry... for which excel might not be the best tool without programming.
Thanks for your comments. You're right to question the possible non-uniqueness and whether Excel is the right tool. Excel is certainly not the best tool, or even a good tool, for storing datasets unless they're quite small really (max low 1,000's of rows I'd say). However, the unique check I put in, and the addition of going one character further than strictly needed, should give some confidence...although if handing over the spreadsheet to less competent users might still be of concern.
To address the next ID issue I personally store a next ID number on the sheet using =MAX([ID Column])+1 and then type that in for new entries. This is only really fine if the number of new entries is low and typically added one at a time. Code is always messy in Excel, especially with all the current macro blocking and warnings so I try to avoid it these days.
@@Up4Excel I also try to avoid Macro/VBA code if possible. Once was the way to go (store a counter in the workbook, at running index numbers on data entry (automatically), and just keep counting). The other thing this automatically took care of: newer re-use an ID. It should count strictly upwards. As a plus, instead of deleting rows with their respective indices, one should mark rows as deleted and filter by that tick.
More ovious: if you only use the ID to split and re-join tables during the update of a model, it is irrelevant if IDs get mixed up by sorting. They only need to stay fixed during runtime of the model - like Power Query, add Index-Column, and quickly forget about that index once the updates are made.
@@renatorosco325 It's a good point about there being no need for the IDs to stay fixed beyond the running of a model, as long as you're certain you won't be using them for anything else it certainly solves the issue.
As for VBA, I suspect that an office script solution might be possible, but I've yet to dig into that so wouldn't know either way at present.
