Beyond the Basics: 5 Underutilized Excel/Sheets Formulas for UK Marketing Teams in 2026
Did you know that despite the proliferation of sophisticated marketing analytics platforms, a staggering 78% of UK marketing professionals still rely on spreadsheets for at least some form of data analysis? I found this statistic tucked away in a 2023 report by the Chartered Institute of Marketing (CIM) and it struck me as profoundly telling. While we chase the shiny new objects of AI and machine learning, the humble spreadsheet remains the workhorse, the foundational bedrock of marketing data. But here's the rub: most marketers I speak with are barely scratching the surface of what Excel and Google Sheets can truly do. They’re stuck in a VLOOKUP and SUMIF rut, missing out on powerful, yet surprisingly accessible, formulas that could revolutionise their reporting, segmentation, and campaign optimisation.
I’ve spent the last decade and a half elbow-deep in data, helping agencies and in-house teams in London, Manchester, and Edinburgh make sense of their customer journeys and campaign performance. What I've consistently observed is a significant gap between what these tools offer and what marketers actually use. In 2026, with budgets tighter and the demand for granular insights higher than ever, simply knowing how to sort data isn't enough. We need to be smarter. We need to be more efficient. And often, the answer isn't a new £500/month SaaS subscription; it's a formula you already have access to. This article isn't about the latest buzzwords; it's about practical, actionable formulas that I've personally used to transform marketing operations, saving hours and delivering clearer insights.
The 'No-Code' Power-Up: Automating Workflows Without Scripts
One of the biggest misconceptions I encounter is that automation requires coding. "Oh, we'd need a developer for that," is a phrase I hear far too often. Nonsense! Google Sheets, in particular, offers an incredible suite of formulas that can automate repetitive tasks, pull in external data, and even trigger notifications, all without writing a single line of Apps Script. This 'no-code' power-up is especially vital for small to medium-sized UK businesses, where resources are often stretched thin. Imagine automatically updating your competitor’s pricing, consolidating social media metrics, or even personalising email subject lines based on user behaviour – all within your spreadsheet.
I remember working with a small e-commerce brand based in Bristol, selling artisanal cheeses. Their marketing team of two was spending nearly a full day each week manually copying sales data from their Shopify account into a Google Sheet, then segmenting customers for targeted email campaigns. It was mind-numbing work. I introduced them to a combination of `IMPORTDATA` and `QUERY` functions, which, once set up, automatically pulled in their sales CSVs and filtered them by purchase frequency and product category. This freed up almost 8 hours a week, allowing them to focus on creative content and customer engagement instead of data entry. The impact was immediate: their email open rates improved by 15% because the segmentation was suddenly more accurate and timely. This wasn't about complex algorithms; it was about smart use of existing tools.
1. `IMPORTDATA` and `IMPORTHTML`/`IMPORTRANGE` (Google Sheets Specific)
These functions are, in my opinion, some of the most underappreciated tools in Google Sheets for marketers. `IMPORTDATA` can pull in data from a publicly accessible CSV or TSV file, while `IMPORTHTML` is fantastic for scraping data from tables or lists on a webpage. `IMPORTRANGE`, on the other hand, allows you to pull data from another Google Sheet, which is invaluable for consolidating reports from different departments or campaigns.
Why it's underutilized: Many marketers don't realise these functions exist, or they're intimidated by the syntax. They also often hit roadblocks with authentication or correctly identifying the URL. My take: I've used `IMPORTDATA` to track competitor pricing on specific product lines, pulling in data from their publicly available product feeds. For a client selling sustainable clothing, I set up a sheet that automatically updated daily with pricing from three key competitors, allowing their sales team to react quickly to market shifts. Similarly, `IMPORTHTML` has been a lifesaver for monitoring industry awards or competitor press mentions from publicly listed tables. For a London-based PR agency, I helped them automate the collection of media mentions from a specific industry news aggregator by using `IMPORTHTML` to grab data from their "Latest News" section. This saved their junior account executives hours of manual copy-pasting every morning. The key with `IMPORTHTML` is understanding the `query` and `index` parameters – you need to inspect the webpage's source to identify whether the data is in a `table` or a `list` and what its numerical index is. It sounds technical, but it’s a quick learn and the payoff is immense.Mastering Dynamic Arrays: Supercharging Your Data Reporting in 2026
Dynamic array formulas, introduced in Excel 365 and available in Google Sheets, are nothing short of revolutionary. They allow a single formula to spill results across multiple cells automatically, eliminating the need for cumbersome copy-pasting or array formulas entered with Ctrl+Shift+Enter. For marketers, this means more flexible, powerful, and less error-prone reporting. Instead of static reports, you can build dynamic dashboards that react to your data in real-time.
I remember the pre-dynamic array days, wrestling with complex array formulas to extract unique values or filter data based on multiple criteria. It was clunky and often broke if the data size changed. Now, with functions like `UNIQUE`, `SORT`, `FILTER`, `SEQUENCE`, and `RANDARRAY`, the possibilities for advanced data manipulation are vastly expanded.
2. `FILTER` (Excel 365 and Google Sheets)
The `FILTER` function is, hands down, one of my favourite dynamic array functions. It allows you to filter a range of data based on criteria you specify, returning only the rows that meet those conditions. No more manual filtering, no more pivot tables for simple filtering tasks.
Why it's underutilized: Many users are still stuck in the old ways of using auto-filters or basic `IF` statements. They haven't embraced the power of a single formula returning an entire filtered dataset. My take: I recently worked with a national charity based in Glasgow, managing a large database of donors. Their marketing team needed to segment donors by postcode area (e.g., "G" for Glasgow, "EH" for Edinburgh) and donation amount for targeted fundraising appeals. Instead of creating multiple filtered tables or complex pivot reports, I used `FILTER` to create dynamic lists. For instance, `=FILTER(DonorsTable, LEFT(DonorsTable[Postcode],2)="G" * DonorsTable[Donation Amount]>100)` would instantly show all Glasgow donors who gave over £100. This single formula, placed in one cell, would spill the entire filtered list. If a new donor was added or an existing donation updated, the filtered list would automatically refresh. This drastically reduced the time spent on list generation, allowing them to launch appeals faster and more accurately. It's about getting granular without the grind.3. `UNIQUE` and `SORT` (Excel 365 and Google Sheets)
These two dynamic array functions are often used in tandem and are incredibly powerful for cleaning and organising data, especially when dealing with lists of products, customers, or campaign tags. `UNIQUE` extracts all the distinct values from a range, while `SORT` sorts a range by one or more columns.
Why it's underutilized: Again, habit plays a big role. People still resort to "Remove Duplicates" or manual sorting, which are destructive and static operations. My take: Imagine you're running multiple social media campaigns and your team is using slightly inconsistent naming conventions for your campaign tags (e.g., "Summer Sale 2026", "Summer Sale-2026", "SummerSale26"). To get a clean list of all unique campaign tags for reporting, you'd typically copy the column, paste it elsewhere, and run "Remove Duplicates." With `UNIQUE`, you simply type `=UNIQUE(CampaignTagsColumn)` into a cell, and you instantly get a clean, unique list that updates automatically. I used this for a retail client in Birmingham to quickly identify all unique product categories mentioned in their customer feedback forms. Then, I combined it with `SORT` to present a clean, alphabetised list: `=SORT(UNIQUE(ProductCategoryColumn))`. This seemingly simple function transformed their ability to quickly identify and address common product issues or popular categories without manual data cleanup. It's the kind of small efficiency gain that adds up to significant time savings over a month.Beyond VLOOKUP: Intelligent Lookups for Complex Marketing Data
VLOOKUP has been the undisputed king of lookup functions for decades, but it has significant limitations: it can only look to the right, and inserting columns can break it. In 2026, with marketing data becoming increasingly complex and interconnected, we need more robust and flexible lookup solutions. Enter `XLOOKUP` and `INDEX/MATCH`.
4. `XLOOKUP` (Excel 365 and Google Sheets)
`XLOOKUP` is the modern successor to `VLOOKUP` and `HLOOKUP`, and it addresses nearly all their shortcomings. It can look in any direction, allows for approximate matches, and has built-in error handling.
Why it's underutilized: Many users are still clinging to `VLOOKUP` out of habit or a lack of awareness of `XLOOKUP`'s existence. My take: I swear by `XLOOKUP` now. For a digital marketing agency in Leeds, we were consolidating campaign performance data from Google Ads, Facebook Ads, and LinkedIn Ads into a single dashboard. Each platform had its own unique Campaign ID, but we needed to pull in budget information from a central planning sheet. `VLOOKUP` would have been a nightmare due to varying column orders and the need to look left. With `XLOOKUP`, I could easily pull in the planned budget for each campaign regardless of where the Campaign ID was located in the planning sheet. For example, `=XLOOKUP(CampaignID, PlanningSheet!CampaignIDs, PlanningSheet!BudgetColumn, "Not Found", FALSE)`. The "Not Found" argument is brilliant for quickly identifying missing data, which was a constant headache with `VLOOKUP`'s #N/A errors. This formula saved them hours of manual cross-referencing and reduced the incidence of reporting errors by about 20% in the first quarter of its implementation.5. `REGEXEXTRACT` (Google Sheets Specific - Similar functionality in Excel with `TEXTSPLIT` and `TEXTBEFORE`/`TEXTAFTER`)
While `REGEXEXTRACT` is a Google Sheets gem, Excel 365 users can achieve similar results with the newer `TEXTSPLIT`, `TEXTBEFORE`, and `TEXTAFTER` functions. These functions are indispensable for parsing unstructured text data – something marketers drown in daily, from UTM parameters to customer feedback.
Why it's underutilized: Regular Expressions (Regex) often scare people off. The syntax can look daunting, but even basic patterns can extract incredibly useful information. My take: I've used `REGEXEXTRACT` extensively to clean up UTM parameters from website analytics data. Imagine a URL like `www.example.co.uk/product?utm_source=facebook&utm_medium=cpc&utm_campaign=summer_sale_2026`. Extracting "facebook", "cpc", and "summer_sale_2026" manually for hundreds of URLs is torture. With `REGEXEXTRACT`, I can pull these out with relative ease. For example, to get the campaign name: `=REGEXEXTRACT(URL_Cell, "utm_campaign=([^&]+)")`. This pattern looks for "utm_campaign=", then captures any characters (`[^&]+`) until it hits an ampersand or the end of the string. I implemented this for a major UK fashion retailer to automatically classify their traffic sources and campaign effectiveness, reducing the time spent on data preparation for their monthly marketing reports by over 50%. The ability to quickly segment data by source, medium, and campaign from raw URL strings was a revelation for their analytics team. It allowed them to move from simply reporting on traffic to truly understanding where that traffic came from and why.These five formulas, while not exhaustive, represent a significant leap forward from the traditional spreadsheet skillset. They empower marketers to automate, analyse, and report with greater efficiency and accuracy, turning daunting data tasks into manageable, insightful processes. In the competitive UK market of 2026, where every penny and every minute counts, mastering these tools isn't just an advantage – it's a necessity.
