Say Goodbye to Power Query: Unpivot Excel Data Effortlessly
Excel Off The Grid reveal two powerful approaches to unpivoting data in Excel: a quick, automated method using pre-built Lambda functions and a hands-on, customizable approach with advanced formulas. Whether you're dealing with merged cells, blank spaces, or complex layouts, these techniques will equip you to tackle it all. You'll learn how to extract key insights from cross-tab data, organize it into a column-based structure, and even automate updates for real-time accuracy. By the end, you won't just know how to unpivot data—you'll understand why formulas can sometimes outshine Power Query in flexibility and accessibility. After all, mastering your tools isn't just about efficiency; it's about unlocking new possibilities for your data. Unpivoting Data in Excel Why Cross-tab Layouts Pose Challenges
Cross-tab layouts, where data is organized in a grid format across rows and columns, are visually intuitive but analytically restrictive. For instance, sales data displayed by regions and product categories in a table may look organized but complicates tasks such as aggregations, trend analysis, or pivot table creation. To make such data usable for analysis, it must be converted into a column-based structure, where each row represents a single data point. This process, known as 'unpivoting,' is essential for creating datasets that are compatible with Excel's analytical tools and functions. Efficient Solution: Pre-built Lambda Functions
For users seeking a quick and automated way to unpivot data, pre-built Lambda functions offer a streamlined solution. These functions, such as `FX Unpivot` and `FX Fill Blank Cells`, can either be accessed from a function library or created within Excel. Here's how they simplify the unpivoting process: Unpivoting Data: The `FX Unpivot` function automatically converts cross-tab layouts into a column-based structure. It extracts headers and values, organizing them into a clean, tabular format suitable for analysis.

Handling Merged Cells: Merged cells often create blank spaces in datasets. The `FX Fill Blank Cells` function fills these gaps with the appropriate values, making sure data consistency and completeness.
This method is particularly useful for users who prioritize speed and automation over manual control. It eliminates the need for complex formulas, making it an excellent choice for straightforward unpivoting tasks. Unpivot with Formulas in Excel… No Power Query!!

Tesla vehicle deliveries drop sharply as Musk backlash affects demand
Tesla posted another big drop in quarterly deliveries on Wednesday, putting it on course for its second straight annual sales decline as demand falters due to backlash over CEO Elon Musk's political stance and an aging vehicle lineup. Tesla said it delivered 384,122 vehicles in the second quarter, down 13.5% from 443,956 units a year ago. Analysts had expected it to report deliveries of about 394,378 vehicles, according to an average of 23 estimates from financial research firm Visible Alpha, though projections went to as low as 360,080 units based on estimates from 10 analysts over the past month. Analysts use the number of vehicles delivered to customers as a metric of success to evaluate both automotive sales and production. 'The market is reacting to the deliveries not being as bad as potentially thought with multiple analysts cutting their forecasts over the past week,' said Seth Goldstein, senior equity analyst at Morningstar. The stock has lost 25% of its value so far this year as investors feared brand damage in Europe, where sales have slumped most sharply, and in the US from Musk's embrace of rightwing politics and his role in spearheading the Trump administration's cost-cutting effort. The day Trump and Musk split publicly in early June, Tesla lost some $150bn in market value. Its share price has somewhat recovered in the ensuing month, but Trump and Musk have likewise reignited their feud as they spar over Trump's sweeping tax bill. Tesla's plummeting deliveries in a steadily growing global EV market come despite Musk saying in April that sales had turned around. The company refreshed its top-selling Model Y crossover earlier this year to boost demand, but the redesign forced a production halt and prompted some buyers to delay purchases in anticipation of the updated version. Most of Tesla's revenue and profit come from its core EV business, and much of its trillion-dollar valuation hangs on Musk's big bet on converting its vehicles into robotaxis. Tesla last month rolled out a robotaxi service in limited parts of Austin, Texas, for a select group of invitees and with several restrictions, including having a safety monitor in the front passenger seat. The pilot was limited, though, with only about a dozen Robotaxis on the road. The US National Highway and Transportation Safety Administration opened an investigation into the launch of the autonomous ride service.

While a cheaper model might help bolster sales, Wall Street expects a second consecutive annual sales decline this year. To achieve Musk's target of returning to growth this year, Tesla would need to hand over more than a million units in the second half - a record and a tough challenge, according to analysts, despite typically stronger sales in the second half.

Microsoft announces another mass layoff, thousands of workers affected
Microsoft is firing thousands of workers, its second mass layoff in months. The tech giant began sending out layoff notices Wednesday. The company declined to say how many people would be laid off but said that it will comprise less than 4% of the workforce it had a year ago. Microsoft said the cuts will affect multiple teams around the world, including its sales division and its Xbox video game business. 'We continue to implement organizational changes necessary to best position the company and teams for success in a dynamic marketplace,' it said in a statement. Microsoft employed 228,000 full-time workers as of last June, the last time it reported its annual headcount. The company said Wednesday that its latest layoffs would cut close to 4% of that workforce, which would be about 9,000 people. But it has already had at least three layoffs this year. Until now, the biggest was in May, when Microsoft began laying off about 6,000 workers, nearly 3% of its global workforce and its largest job cuts in more than two years as the company spent heavily on artificial intelligence. Microsoft also cut another 300 workers based out of its Redmond, Washington headquarters in June, on top of nearly 2,000 who lost their jobs in the Puget Sound region in May, according to notices it sent to Washington state employment officials. The layoffs announced in May were heavily focused on people in software engineering and product management roles, according to lists the company sent to employment agencies in Washington and California — where the cuts also hit Microsoft offices in the San Francisco Bay Area. Microsoft's chief financial officer Amy Hood said on an April earnings call that the company was focused on 'building high-performing teams and increasing our agility by reducing layers with fewer managers.' The company has repeatedly characterized its recent layoffs as part of a push to trim management layers, but the May focus on software engineering jobs has fueled worries about how the company's own AI code-writing products could reduce the number of people need for programming jobs. Microsoft CEO Satya Nadella said earlier this year that 'maybe 20, 30% of the code' for some of Microsoft's coding projects 'are probably all written by software.'

Microsoft to cut another 9,000 jobs in bid to slash costs
Microsoft has announced plans to eliminate approximately 9,000 jobs worldwide, marking the latest significant round of redundancies as the US technology company seeks to reduce costs. The cuts are understood to affect less than 4 per cent of its total global workforce. A company spokesman confirmed the move, stating: "We continue to implement organisational changes necessary to best position the company and teams for success in a dynamic marketplace." This marks the largest reduction in staff since early 2023, when Microsoft fired 10,000 workers – nearly 5 per cent of its then-workforce – amidst a broader trend within the technology sector to scale back the rapid expansion witnessed during the pandemic era. The latest cuts are thought to impact different teams and country operations as part of efforts to cut layers of management. The company's gaming business is among areas where Microsoft will 'end or decrease work', according to an internal memo. 'To position gaming for enduring success and allow us to focus on strategic growth areas, we will end or decrease work in certain areas of the business and follow Microsoft's lead in removing layers of management to increase agility and effectiveness,' Phil Spencer, Microsoft's chief executive of gaming, said. The cuts come after Microsoft axed around 6,000 roles in May and some 1,000 in January. Microsoft employed 228,000 full-time workers as of last June, the last time it reported its annual headcount. About 55% were in the US.
