Turn Data Sideways



Someone built this lookup table sideways, stretching across C1:N2. I realize that I could use HLOOKUP instead of VLOOKUP, but I prefer to turn the data back to a vertical orientation.

Copy C1:N2. Right-click in A4 and choose the Transpose option under the Paste Options. Transpose is the fancy Excel word for “turn the data sideways.”

Copy the horizontal lookup table in C1:N2. Right-click in a blank cell. The fourth icon under Paste Options is called Transpose. Choose that and you will paste a sideways copy of the original table.

I transpose a lot. But I use Alt+E, S, E, Enter to transpose instead of the right-click.

There is a problem, though. Transpose is a one-time snapshot of the data. What if you have formulas in the horizontal data? Is there a way to transpose with a formula?

The first way is a bit bizarre. If you are trying to transpose 12 horizontal cells, you need to select 12 vertical cells in a single selection. Start typing a formula such as =TRANSPOSE(C2:N2) in the active cell but do not press Enter. Instead, hold down Ctrl+Shift and then press Enter. This puts a single array formula in the selected cells. This TRANSPOSE formula is going to return 12 answers, and they will appear in the 12 selected cells, as shown below.

Select the 12 cells B4:B15. Type a formula =TRANSPOSE(C2:N2) but do not press Enter. Instead, hold while holding down Ctrl and Shift, press Enter. This enters a single formula in 12 cells at one time.

As the data in the horizontal table changes, the same values appear in your vertical table, as shown below.

The results: as the original formulas in C2:N2 recalculate, the results in the vertical range are updated.

But array formulas are not well known. Some spreadsheet rookie might try to edit your formula and forget to press Ctrl+Shift+Enter.

To avoid using the array formula, use a combination of INDEX and ROW, as shown in the figure below. =ROW(1:1) is a clever way of writing the number 1. As you copy this formula down, the row reference changes to 2:2 and returns a 2.

The INDEX function says you are getting the answers from C2:N2, and you want the nth item from the range.

A different solution that does not require Ctrl+Shift+Enter. The formula for January in B4 is =INDEX($C$2:$N$2,ROW(1:1)). The ROW(1:1) is a complicated way to write the number 1.

In the figure below, =FORMULATEXT in column C shows how the formula changes when you copy down.

As you copy that formula down, the reference to ROW(1:1) automatically changes to ROW(2:2) and so on.

Rethinking Agentic AI

 # Rethinking AI Agents: Why Intelligence Beats Integration Every Time ## More Tools Won't Save a Thoughtless Agent Every week, another development team ships an AI agent loaded with integrations — web search, vector databases, code runners, calendar hooks, payment gateways. The demo looks impressive. The stakeholders nod. Then the agent hits its first real user in a messy, unpredictable situation, and the cracks appear fast. The uncomfortable truth? Most AI agents fail not because they lack access to information, but because nobody taught them how to *think* about it. The industry has quietly developed a bad habit: treating agent-building like a hardware upgrade. Slow processor? Add RAM. Agent underperforming? Add tools. This logic sounds reasonable until you realize that intelligence doesn't accumulate through connection counts. A library card doesn't make someone well-read. --- ## Competence Isn't a Plugin Here's a useful mental test. Imagine hiring someone for a...

Quantum Computing

  Quantum computing is a new kind of computing that uses the laws of quantum physics to solve certain problems much faster than classical computers.  It doesn’t replace your laptop but can tackle very complex simulations, optimization, and cryptography‑style tasks that are intractable for ordinary machines.  *** ### What is quantum computing? Quantum computing is a computing paradigm that uses quantum‑mechanical phenomena—like superposition, entanglement, and interference—to represent and process information in new ways. Instead of classical bits (0 or 1), quantum computers use **qubits**, which can be in a mix of 0 and 1 at the same time, enabling parallel computation.  *** ### Classical bits vs. qubits - A **classical bit** is either 0 or 1; operations are deterministic and sequential.  - A **qubit** can be 0, 1, or any quantum “blend” of both, written as $$ \alpha|0\rangle + \beta|1\rangle $$, where $$ \alpha $$ and $$ \beta $$ are complex numbers capturing p...

Why Every BI Professional Needs to Learn Agentic AI in 2026

Meta Description:  Agentic AI is transforming business intelligence. Learn why BI professionals must embrace autonomous AI agents to stay relevant — with practical examples, skills to build, and a BI Lead's honest perspective on the shift. Tags:   Agentic AI  ·  Business Intelligence  ·  Power BI  ·  AI Agents  ·  Data Analytics  ·  Future of BI  ·  Career Growth Let me be blunt: if you're a BI professional in 2025 and you haven't started paying attention to agentic AI, you're already behind. I'm not saying that to scare you. I'm saying it because I've spent over a decade building dashboards, tuning SQL queries, and wrangling Power BI data models — and nothing in my career has shifted the landscape as fast as agentic AI. Not self-service analytics. Not cloud migration. Not even the first wave of AI/ML. This is different. And here's why. What Exactly Is Agentic AI? Forget the chatbot hype for a second.
