I recently picked up "Double Efficiency Work Method: Excel Must-Know Functions You'd Regret Not Knowing (Second Edition) (Essential Data Statistical Computing Power for the Big Data Era!)", and I have to say, it has completely revolutionized how I approach spreadsheets. For years, I've been getting by with the basics of Excel, thinking I was doing alright. But this book showed me just how much I was missing out on. The author's ability to break down complex functions into digestible, understandable steps is remarkable. It’s not just about memorizing formulas; it’s about grasping the underlying logic and seeing how they can be applied to solve real-world data challenges. For instance, the chapters on data aggregation and summarization were a game-changer for me. Previously, tasks like compiling sales figures from different regions would take me ages, involving a lot of manual manipulation. Now, with the techniques outlined in the book, I can achieve the same results in a fraction of the time, with far greater accuracy. The emphasis on "statistical computing power for the big data era" is incredibly timely. In today's environment, being able to effectively analyze and interpret data is crucial for making informed business decisions. This book provides the essential tools and knowledge to do just that. What I also found particularly helpful are the practical examples and case studies. They illustrate the power of each function in a very concrete way, making it easy to see how you can implement these techniques in your own work. It's like having a personal Excel coach guiding you through every step. If you're looking to truly unlock the potential of Excel and boost your productivity, this book is an absolute must-read. It's more than just a manual; it's a roadmap to becoming an Excel power user.
评分這本書《翻倍效率工作術：不會就太可惜的Excel 必學函數(第二版) (大数据时代必备的资料统计运算力！)》真的是一本讓我驚豔的工具書！我一直以來都覺得Excel是一個很重要的工具，但總是在一些複雜的資料處理上感到力不從心，常常花費很多時間卻成效不彰。讀了這本書之後，我才發現原來Excel有這麼多強大的函數，可以讓我們的效率「翻倍」！作者的講解非常細緻，不會讓你覺得只是枯燥的公式教學，而是深入淺出地解釋了每個函數背後的邏輯和應用情境。我特別喜歡書中提到的一些函數，能夠幫助我快速地從大量的資料中找出關聯性，並且做出更有意義的分析。過去我做報表可能要花很多時間去整理和匯總數據，但是現在透過書中教的函數，我可以自動化很多流程，省下了大量的時間。而且，這本書的「第二版」內容更新，對於我們現在身處的大數據時代來說，非常具有指導意義。它不只教你「怎麼用」函數，更教你「為什麼要用」以及「什麼時候用」。這種引導式的學習方式，讓我能夠真正地理解這些函數的精髓，並且靈活運用到不同的工作場景。我認為對於任何一個在辦公室工作的人來說，這本書都絕對是一本必備的參考書。它不僅能夠幫助你提升個人的工作效率，更能夠讓你掌握處理大數據的關鍵能力，在職場上更具競爭力。我強烈推薦給所有想要成為Excel達人，並且提升工作效率的朋友們！
评分這本《翻倍效率工作術：不會就太可惜的Excel 必學函數(第二版) (大数据时代必备的资料统计运算力！)》，真的讓我重新認識了Excel的威力。我一直以為自己對Excel已經很熟練了，至少基本的加減乘除、樞紐分析這些我都能應付，但這本書一翻開，就顛覆了我過去的認知。作者在書中介紹的函數，很多都是我聽都沒聽過的，但當我實際操作書中的範例時，才發現這些函數有多麼的神奇和實用。舉例來說，過去我要做一些資料比對，常常是複製貼上，然後手動一個一個對，耗時又容易出錯。但是書中介紹了一個叫做「VLOOKUP」的函數（請注意，這裡只是舉例，書中內容非常豐富），讓我能夠輕輕鬆鬆地將不同表格的資料串聯起來，而且準確度高到不行。還有一些進階的邏輯函數和統計函數，更是讓我看到了處理複雜資料的可能性。書中不僅是單純的函數教學，更重要的是它教你如何「思考」，如何運用這些函數來解決實際工作中的問題。它強調的「大数据时代必备的资料统计运算力！」這個概念，我覺得非常貼切，在現今資訊爆炸的時代，如果沒有這些處理資料的能力，真的會被時代淘汰。這本書就像是我的「Excel隨身秘笈」，我現在隨時帶著，遇到問題時翻閱一下，很快就能找到解決方案。對於需要經常與數字打交道的上班族來說，這本書絕對是提升工作效率、增加職場競爭力的利器。它讓我從「會用Excel」晉升到「精通Excel」，我非常推薦！
评分Having just finished "Double Efficiency Work Method: Excel Must-Know Functions You'd Regret Not Knowing (Second Edition) (Essential Data Statistical Computing Power for the Big Data Era!)", I'm genuinely impressed by the wealth of practical knowledge it contains. As someone who works extensively with data, I'm always on the lookout for ways to streamline my workflow and improve my analytical skills. This book delivers on all fronts. The author has a knack for demystifying complex Excel functions, presenting them in a clear and accessible manner that makes learning enjoyable. What sets this book apart is its focus on real-world applications. Instead of just reciting formulas, it guides you through how to leverage these functions to solve common business problems. The examples provided are highly relevant and easy to adapt to one's own data sets. I found the sections on conditional formatting and data validation particularly useful for ensuring data integrity and making spreadsheets more user-friendly. The "big data era" subtitle is not an overstatement; the book truly equips you with the statistical computing power needed to navigate today's data-intensive environment. It’s like having a personal tutor who reveals all the shortcuts and advanced techniques that can save you hours of work. I particularly appreciate the author's emphasis on efficiency – hence the "double efficiency" in the title. This isn't just about learning functions; it's about learning to use them in a way that maximizes productivity. If you're looking to elevate your Excel game and gain a significant edge in your career, this book is an indispensable resource. It’s an investment that will undoubtedly pay dividends in terms of time saved and improved decision-making.
评分Okay, let me tell you about this book, "Double Efficiency Work Method: Excel Must-Know Functions You'd Regret Not Knowing (Second Edition) (Essential Data Statistical Computing Power for the Big Data Era!)". I was initially drawn in by the promise of "double efficiency," which, let's be honest, can sometimes be a bit of marketing hype. However, as someone who spends a significant amount of time wrestling with spreadsheets for my job, I figured it was worth a shot. And boy, am I glad I did! This isn't your typical dry textbook. The author manages to make what could be a mundane topic surprisingly engaging. What really impressed me was the practical approach. Instead of just listing functions, the book dives deep into *why* you would use a particular function and *how* it can solve real-world problems. I've encountered situations where I’ve spent ages manually sifting through data, only to find out later that there was a specific Excel function that could have done it in a fraction of the time. This book has opened my eyes to so many of those "aha!" moments. The explanations are clear, concise, and the examples are well-chosen, making it easy to follow along and immediately apply what you've learned. The focus on "must-know" functions for the big data era is particularly relevant. It feels like the book is directly addressing the challenges and opportunities we face in today's data-driven world. It's not just about basic calculations anymore; it's about extracting meaningful insights and making informed decisions. This book is equipping me with the tools to do just that. It’s like having a seasoned Excel guru guiding you step-by-step, revealing all the clever shortcuts and powerful features that most people completely miss. If you're tired of feeling limited by your Excel skills, or if you're looking to truly harness the power of data in your work, this book is an absolute game-changer. It’s practical, it’s relevant, and it delivers on its promise of boosting your efficiency.

I'm not exaggerating when I say it's a revelation. I consider myself reasonably proficient with Excel, but this book has blown my mind with its depth and practicality. The author doesn't just present functions; they weave them into relatable scenarios that make you think, "Wow, I've been doing this the hard way for years!" For instance, I used to struggle with consolidating data from multiple sources. It was always a tedious process of copying, pasting, and hoping I didn't miss anything. Then I stumbled upon the sections on advanced lookup and reference functions – it's like a magic wand! Suddenly, I can pull information from different worksheets seamlessly and accurately. The explanations are crystal clear, with well-designed examples that illustrate the concepts perfectly. The emphasis on "statistical computing power for the big data era" isn't just a catchy subtitle; it's a core theme that runs through the entire book. It empowers you to move beyond basic calculations and truly start analyzing data to uncover trends and make informed decisions. I particularly appreciate how the book encourages a problem-solving approach. It doesn't just show you how to use a function; it teaches you how to think strategically about which function to apply to achieve your desired outcome. It's like upgrading from a basic calculator to a powerful scientific instrument. This is the kind of knowledge that can genuinely transform your work.
