Murray Sargent just received the first-ever Microsoft Accessibility Lifetime Achievement Award. Murray has had a huge impact for so many years and it's great to see this recognition. I've known Murray for at least 25 years, and love seeing the impact he had on people like Alex, one of the senior engineers on Excel Copilot. techcommunity.microsoft.com/…

It's crazy my brain has a subconscious place for "don't copy anything, you already have something important copied but not pasted yet."

Fun Fact: It's not the cloud that the world's compute runs on, it's a single Excel spreadsheet with VBA that makes the earth turn

Thanks for sharing your photos, Ken! Wish I’d been at that “old guard” table, to catch up with everyone!
I've been having an amazing week in London at @ExcelSummit. I pre-gamed the conference with some of the Excel "old guard" and went out with Wyn Hopkins and Cristiano Galvao another evening. Nothing better than catching up with friends in person! 😄

🎥The recording for our Vancouver #PowerBI and Modern #Excel meet-up is available here: youtube.com/watch?v=-JEGLKct… We had a great time with @exceloffthegrid exploring blank cells in Excel — what they are, when they stop being blank, and why they sometimes appear as zero. 0️⃣

**DATE CORRECTION** The meet-up is on May 7, not May 14!
What is nothing? Does it exist? In the context of #Excel, there is an answer, which we will explore with Mark Proctor on May 14. Once we understand how Excel handles blank values, we can not only work with nothingness, but bend it to our will!💪 RSVP here: meetup.com/vancouver-power-b…

Happy Pi Day! Excel's date format examples use March 14th. Tribute to Pi, or strange coincidence? #Excel #PiDay

With @msexcel now offering a native choice between @AnthropicAI Claude Opus 6.3 and @OpenAI GPT 5.2, I show how that Hanks Pizza Copilot commercial would have given even better advice by choosing Claude. youtu.be/HtgXkOFto3U

Yes, the results for Hank were definitely real. Nice analysis by @MrExcel... I often like running both models to check each others work. youtube.com/watch?v=oBqKKy_M… youtube.com/watch?v=HtgXkOFt…

BIG NEWS *INCREDIBLE DISCOVERY* Kathleen Pettigrew, the real Miss Moneypenny, private papers FOUND! A year ago I rushed down to #Sidmouth in beautiful Devon because the museum had received an anonymous donation. I couldn’t believe it. The trailblazing MI6 officer’s entire life contained within one simple storage box, a treasure trove of personal photographs, diaries, passports, mysterious reports and papers, maps, foreign currency, a plethora of personal, private and secret letters, as well as important MI6 ephemera never before seen. You can read all about the discovery in the paperback of #HerSecretService in the new Postscript. You can also look forward to future posts about the amazing items in the collection. I am delighted that the collection has recently been acquired by the Sid Vale Association and will be on future display at Sidmouth Museum for all to enjoy! I am speaking about Kathleen Pettigrew in Sidmouth tomorrow afternoon, Thursday 12 March. Event details in post below ⬇️ Please do join us. @wnbooks @NorthbankTalent @SidmouthMuseum @BBCDevon @sidmouthherald @DevonLiveNews @JeremyVineOn5 #womenshistorymonth #MI6 #spyhistory #herstory

In 2021, after 6 years of shopping at my local Sainsbury’s and tracking where I parked each time on a spreadsheet, I completed all 211 parking spots the store had to offer. In 2024 I moved to a new town - and guess what I’ve been busy doing since :) A thread 🧵
