Understand the power of dynamic arrays: a single formula can generate new and vastly more efficient spreadsheet possibilities. This book introduces spreadsheet users to dynamic array functions in Microsoft Excel 365, defines and details the distinctive ways in which they work, and shows how they can be applied to a wide swath of data-analytic tasks.
While array formulas and functions have long held a place in the spreadsheet toolbox (although, for many of us, shunted to an obscure corner), the dynamic array engine offers a more user-friendly and intelligible set of means for manipulating spreadsheet data in the array mode. The single-formula, multi-cell capability of dynamic arrays has been extended to nearly all existing spreadsheet functions, offering a new, default way of working. As a result, many tasks can now be executed with dynamic arrays without having to resort to the new functions at all.
After defining arrays and dynamic array formulas, this book helps you examine the dynamic array property of lifting and how it impacts the formulas, including those written with existing functions. Plenty of illustrations and formulas along the way help you get comfortable using them. From there, you will learn Excel 365's new dynamic functions, including the 14 currently in rollout, each accompanied by instructive examples. In many cases, the examples demonstrate how the new functions can work with long-available functions, such as MID, IF, COUNTIF, etc., which now also boast dynamic array functionality.
- Unlock the dynamic array potential in Microsoft Excel
- Apply dynamic array functions and confidently direct them to real-world spreadsheet tasks
- Know the distinctive ways in which arrays work and can be applied to numerous data-analytic tasks
Who This Book Is For
Users of Excel 365 and beyond who are comfortable with, but not necessarily expert in, formula writing, as well as those who are unaware of or not fluent with dynamic arrays. It is also valuable to data journalists and other professionals in need of spreadsheet skills who may unaware of dynamic arrays, and the time they could save by applying them to their work.
商品描述(中文翻譯)
了解動態陣列的強大功能:單一公式可以產生新的且更有效率的電子表格可能性。本書向 Microsoft Excel 365 的電子表格使用者介紹動態陣列函數,定義並詳細說明它們的獨特運作方式,並展示如何將其應用於各種數據分析任務。
雖然陣列公式和函數在電子表格工具箱中長期佔有一席之地(儘管對於我們中的許多人來說,這些功能被擠到了不顯眼的角落),但動態陣列引擎提供了一組更友好且易於理解的方式來操作電子表格數據。動態陣列的單一公式、多單元格能力已擴展到幾乎所有現有的電子表格函數,提供了一種新的默認工作方式。因此,許多任務現在可以使用動態陣列執行,而無需完全依賴新的函數。
在定義陣列和動態陣列公式之後,本書幫助您檢視動態陣列的提升特性及其對公式的影響,包括那些使用現有函數編寫的公式。沿途有大量的插圖和公式幫助您熟悉它們。接下來,您將學習 Excel 365 的新動態函數,包括目前正在推出的 14 種,每種都附有指導性範例。在許多情況下,這些範例展示了新函數如何與長期可用的函數(如 MID、IF、COUNTIF 等)一起運作,這些函數現在也具備動態陣列功能。
您將學到什麼
- 解鎖 Microsoft Excel 中的動態陣列潛力
- 應用動態陣列函數,自信地將其指向現實世界的電子表格任務
- 了解陣列的獨特運作方式及其在多種數據分析任務中的應用
本書適合誰
本書適合 Excel 365 及以後版本的使用者,他們對公式編寫感到舒適,但不一定是專家,以及那些對動態陣列不熟悉或不流利的人。對於數據記者和其他需要電子表格技能的專業人士來說,本書也非常有價值,他們可能對動態陣列不熟悉,並且不知如何通過應用它們來節省時間。
作者簡介
作者簡介(中文翻譯)
艾伯特·艾拉·卡茨是來自紐約的本地人,目前居住在倫敦。他已經教授 Excel 25 年,並在大西洋兩岸的學習者中探索其應用。他是兩本 Apress 出版的 Excel 書籍的作者——Microsoft Excel 2010 和 Excel 2010 Made Simple,並撰寫了 spreadsheetjournalism.com 的部落格,還為 datajournalism.com、Irish Tech News、datadrivenjournalism.net 和棒球期刊 By the Numbers 貢獻了與 Excel 相關的文章。他在電子表格方面的工作曾被《衛報》、《華爾街日報》、《Freakonomics》部落格和 Excel 專家 Chandoo 引用,並於 2018 年在巴黎的 Sciences Po 大學舉辦了一個以 Excel 為主題的五場工作坊,主題為數據故事。艾伯特擁有紐約州立大學石溪分校的社會學博士學位。關於動態陣列函數的書籍構思源於一種感覺,即這些強大的工具的使用仍然很少,且大量的電子表格使用者對其能夠促進各種廣泛任務的能力仍然不甚了解。
