Mastering Excel's SCAN Function What is the SCAN Function?
The SCAN function processes each value in an array by applying a function that combines the current value with the result of the previous calculation. It requires three key arguments to function effectively: Initial Value: The starting point for the calculation, which serves as the base for subsequent operations.
The starting point for the calculation, which serves as the base for subsequent operations. Array: The dataset to iterate through, providing the values to be processed sequentially.
The dataset to iterate through, providing the values to be processed sequentially. Function: The operation applied at each step, defining how the current value interacts with the previous result.
This structure makes SCAN particularly useful for scenarios where each calculation depends on the outcome of the previous step. Examples include cumulative totals, iterative financial models, or any task requiring step-by-step computations. Practical Applications of SCAN
The SCAN function is highly versatile and can simplify a wide range of tasks. Its ability to handle sequential calculations makes it a valuable tool for various practical applications: Running Totals: SCAN calculates cumulative sums by iterating through an array and adding the current value to the previous result. This is particularly useful for tracking progressive totals in datasets.

The integration of the LAMBDA function significantly enhances SCAN's flexibility. LAMBDA allows users to define custom functions tailored to specific needs, allowing more complex and adaptable workflows. Within SCAN, placeholders like 'previous' (representing the prior result) and 'value' (representing the current array element) can be used to create highly customized operations.
For instance, you can define a LAMBDA function to calculate weighted averages, conditional sums, or other specialized computations. This capability simplifies complex workflows, reduces formula clutter, and allows you to reuse custom functions across multiple scenarios. By combining SCAN with LAMBDA, you can unlock a new level of precision and efficiency in your Excel calculations. Combining Arrays for Advanced Analyses
SCAN's ability to process multiple arrays simultaneously adds another layer of functionality. For example, you can combine inflows and outflows into a single dataset for analysis. This feature is particularly valuable in financial and operational contexts, where multiple variables interact dynamically.
By structuring data into arrays, SCAN can efficiently handle intricate relationships and dependencies. This capability is especially useful for tasks such as: Analyzing cash flow patterns by combining revenue and expense data.
Tracking inventory changes by integrating stock inflows and outflows.
Modeling financial scenarios that involve multiple interdependent variables.
This ability to manage complex datasets within a single formula streamlines workflows and enhances the accuracy of your analyses. Integrating Built-in Functions and Simplifying Formulas
SCAN works seamlessly with Excel's built-in functions, such as SUM, MIN, and MAX, allowing you to enhance its functionality without additional complexity. Additionally, SCAN supports eta reduction, which enables you to reference a function name directly without defining a LAMBDA. For example, instead of creating a custom LAMBDA for summation, you can simply use SUM as the function argument in SCAN.
This feature not only reduces formula complexity but also improves readability, making it easier to understand and maintain your calculations. By using built-in functions alongside SCAN, you can achieve powerful results with minimal effort. Understanding SCAN's Limitations
While SCAN is a robust and versatile tool, it does have some limitations that users should be aware of. For instance, functions like COUNT may not behave as expected because SCAN only passes two values—the previous result and the current value—into the function. This can lead to unexpected outcomes if the function relies on additional parameters or broader dataset contexts.
Additionally, SCAN's reliance on sequential processing means it may not be suitable for tasks requiring non-linear or independent calculations. Understanding these nuances is crucial for effectively integrating SCAN into your workflows and avoiding potential pitfalls. Corkscrew Calculations: A Key Strength
One of SCAN's standout capabilities is its ability to handle corkscrew calculations. These involve iterative processes where the result of one period directly influences the next. For example, SCAN can calculate opening balances, movements, and closing balances in a single formula. This iterative capability is indispensable for tasks such as: Financial modeling, where accurate projections depend on sequential calculations.
Inventory tracking, where stock levels are updated based on inflows and outflows.
Operational planning, where resource allocation depends on prior usage data.
By automating these processes, SCAN eliminates the need for manual adjustments and ensures consistency across calculations, making it an invaluable tool for professionals in finance, operations, and beyond.

Dollar firms as markets brace for Iran response to US attacks
SINGAPORE, June 23 (Reuters) - The U.S. dollar firmed slightly on Monday as anxious investors sought safety, although the moves were muted so far suggesting markets were waiting for Iran's response to U.S. attacks on its nuclear sites that have exacerbated tension in the Middle East. The major moves were in the oil market, with oil prices hitting a five-month high, while global stocks slipped in the first market reaction to the U.S. attacks over the weekend. In currency markets, the dollar advanced broadly against most rivals. It was up 0.25% against the Japanese yen at 146.415 after touching a one-month high earlier in the session. The euro was 0.33% lower at $1.1484, while the Australian dollar , often seen as risk proxy, weakened 0.2% to $0.6437, hovering near its lowest level in over three weeks. That left the dollar index , which measures the U.S. currency against six other units, 0.12% higher at 99.037. Sterling was 0.25% lower at $1.34175, while the New Zealand dollar also fell 0.24% to $0.5952. Carol Kong, currency strategist at Commonwealth Bank of Australia, said the markets are in wait-and-see mode on how Iran responds, with more worries about the positive inflationary impact of the conflict than the negative economic impact. "The currency markets will be at the mercy of comments and actions from the Iranian, Israeli and U.S. governments. The risks are clearly skewed to further upside in the safe haven currencies if the parties escalate the conflict." Iran vowed to defend itself a day after the U.S. dropped 30,000-pound bunker-buster bombs onto the mountain above Iran's Fordow nuclear site. American leaders urged Tehran to stand down while pockets of anti-war protests emerged in U.S. cities. In a step towards what is widely seen as Iran's most effective threat to hurt the West, its parliament approved a move to close the Strait of Hormuz. Nearly a quarter of global oil shipments pass through the narrow waters that Iran shares with Oman and the United Arab Emirates. "Markets appear to be treating the U.S. strikes on Iran as a contained event for now, rather than the start of a broader war," said Charu Chanana, chief investment strategist at Saxo. "The muted haven flows suggest investors are still assuming this is a one-off escalation, not a disruption to global oil supply or trade." While the dollar has reprised its role as a safe haven due to the rapid escalation in geopolitical tension, the relatively muted moves suggested investors remain wary of going all in on the greenback. The U.S. currency has dropped 8.6% this year against its major rivals as economic uncertainty from President Donald Trump's tariffs and concern over their impact on U.S. growth has led to investors scurrying for alternatives. In cryptocurrencies, bitcoin was up 1.3% in early trading after dropping about 4% on Sunday, while ether rose 2.3% on Monday after sliding 9% in the previous session.

Oil rises and US stock futures slide as markets react to US strike on Iran nuclear sites
The price of oil rose and U.S. stock futures fell as global markets react to the U.S. strike against nuclear targets in Iran. The price of Brent crude oil, the international standard, rose 3.9% to $80 a barrel. U.S. crude rose 4.3% to $77 a barrel. Futures for the S&P 500 fell 0.6%. Treasury yields fell slightly. On Saturday, U.S. forces attacked three Iranian nuclear and military sites, further increasing the stakes in the war between Israel and Iran. The conflict has sent oil prices yo-yoing over the last week, which has in turn caused see-saw moves for the U.S. stock market, because of rising and ebbing fears that the war could disrupt the global flow of crude. Iran is a major producer of oil and also sits on the narrow Strait of Hormuz, through which much of the world's crude passes.
