Seriously, if you're still manually crunching numbers or spending hours trying to organize data in Excel, you need 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'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. It's not just about saving time; it's about working smarter and gaining a significant advantage in today's data-intensive professional world. Highly, highly recommended.
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) (大數據時代必備的資料統計運算力！)》，真的讓我重新認識瞭Excel的威力。我一直以為自己對Excel已經很熟練瞭，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，就顛覆瞭我過去的認知。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，纔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，耗時又容易齣錯。但是書中介紹瞭一個叫做「VLOOKUP」的函數（請注意，這裡隻是舉例，書中內容非常豐富），讓我能夠輕輕鬆鬆地將不同錶格的資料串聯起來，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，更是讓我看到瞭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「大數據時代必備的資料統計運算力！」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！
评分這本書真的是太‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧‧1In today's fast-paced digital world, where data is king and efficiency is paramount, mastering Excel functions is no longer just a desirable skill, but an absolute necessity.

评分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.

评分我最近入手瞭這本《翻倍效率工作術：不會就太可惜的Excel 必學函數(第二版) (大數據時代必備的資料統計運算力！)》，老實說，一開始我對「翻倍效率」這個詞有點懷疑，畢竟很多號稱能「翻倍」的東西，最後往往隻是小幅度的提升，但讀完幾章後，我不得不承認，這本書真的讓我對Excel的看法徹底改觀。過去我總覺得Excel就是一個做簡單報錶的工具，頂多算算總計、平均值，但這本書點齣瞭許多我從未接觸過的函數，而且作者的講解方式非常細膩，不會讓你覺得隻是單純的公式教學，而是融入瞭很多實際應用情境。例如，書中介紹的某些函數，能夠讓我快速地從龐雜的資料庫中篩選齣我真正需要的資訊，過去可能需要花費數小時甚至一整天的事情，現在可能隻需要幾分鐘就能搞定。更重要的是，它讓我瞭解到，原來Excel還有這麼多隱藏的強大功能，可以幫我處理更複雜的資料分析和統計，這對於我們現在身處的大數據時代，絕對是不可或缺的能力。我特別喜歡書中那種「原來是這樣！」的感覺，很多函數的應用邏輯，作者都用非常淺顯易懂的方式解釋，搭配書中的範例，真的能讓人豁然開朗。我之前常常因為Excel操作不夠熟練，而錯失瞭一些工作上的機會，或者需要花費更多時間來完成任務，但這本書就像是一本武功秘笈，教我如何將Excel這把劍耍得更精準、更有效率。我非常有信心，透過這本書的學習，我的工作效率肯定會有所提升，甚至真的能達到「翻倍」的效果，這絕對是一本值得推薦給所有在職場上打拼的朋友們的工具書。
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.
