前几天我的一个朋友打电话给我，询问他们如何在不使用Office的情况下在计算机上快速查看(Office)PowerPoint演示文稿，因为他们没有安装它。我告诉她不要担心，因为有很多方法可以查看Office文件，而实际上不需要Office。
总的来说，多亏了谷歌(Google)和云计算，现在您拥有功能齐全的办公生产力套件，可以直接从浏览器运行。一旦Google推出了Google Docs、Sheets和Slides，它就迫使微软(Microsoft)重新考虑他们的整个Office战略。现在微软(Microsoft)有一个免费版本的Office套件，您可以在线使用它来创建和编辑文件。
在本文中，我将向您展示几种不同的工具，您可以使用它们来免费打开PDF(PDFs)、Microsoft Office文件、Photoshop文件等。现在，免费的主要问题是功能有限。以Word的在线Office为例，让你做基本的编辑任务，但不能做任何更高级的任务，如邮件合并或脚注等。但是，如果你只需要查看文件，这些解决方案将是正好。
Microsoft Office 在线免费版
如果您尝试查看Office文档（Word、Excel或PowerPoint），那么最好的选择是使用Office Online。您只需访问 www.office.com 并使用您的Microsoft帐户登录。这是使用他们的免费工具的唯一要求。
通过Office在线应用，您可以获得核心的Microsoft Office应用：Word、Excel、PowerPoint和OneNote。但是，您将无法使用这些工具来查看Access数据库、Visio图表或Microsoft Project文件。
对于核心应用程序，您可以创建新文件，这些文件将自动存储在您的 OneDrive 文件夹中，或者您可以从本地计算机上传新文档。
从下面可以看出，Word 的在线版本没有(Word)完整版Word上的功能区界面所具有的所有选项卡。它完全缺少参考和邮件(Mailings)。此外，所有其他选项卡只有一些基本选项，但其余选项均缺失。对于大多数人来说，免费版本就足够了，但这就是微软(Microsoft)为需要所有功能的人提供Office 365订阅的原因。(Office 365)
同样的信息也适用于Excel和PowerPoint的在线版本。非常(Great)适合查看Office文件，适合编辑，但功能不全。总体而言，如果您需要查看Office文件并对它们进行简单的编辑，您应该尝试一下。
Google 文档(Google Docs)、表格(Sheets)、幻灯片(Slides)和云端硬盘(Drive)
除了Office在线，谷歌(Google)的在线工具集也可以打开Microsoft Office文件。因此，如果您在Google生态系统中并且只需要查看一些MS Office文档，请尝试在Google Docs、Google Sheets或Google Slides中打开它们。
我在Google Docs中打开了完全格式化的简历，它看起来与Word中的完全一样！然后，我可以根据需要对其进行编辑，而不会出现任何问题。我还可以将文件从Google Docs(Google Docs)保存回Word格式。
我喜欢所有Google工具的地方在于它们支持附加组件，这些附加组件可以为基本程序添加许多功能。例如，Google Docs 可以使用 Office online 不支持的附加组件来处理引文和(Google Docs)参考书目(Office)。
如果您需要打开PDF文件，您可以直接使用Google Chrome，而不是下载免费的 PDF 阅读器(free PDF reader)。如果只是查看和打印，谷歌浏览器(Google Chrome)是一个不错的选择。只需将(Just)PDF拖放到Chrome中打开的选项卡中即可查看PDF文件。
如果您需要查看其他不同扩展名的文件类型(view other files types with different extensions)，我建议您尝试使用Google Drive。Google Drive可用于查看Adobe Photoshop文件和一大堆通常需要特定应用程序的其他文件。你显然不能编辑PSD文件或类似的东西。如果您想这样做，您需要其他程序，例如GIMP或Paint.NET。但是，对于查看文件，Google Drive非常棒。
尽管这些工具已经存在了一段时间，但您可能还不知道它们可以执行的所有不同功能。两家公司也一直在添加新功能，因此如果您已经很长时间没有使用它们，最好现在就检查一下。享受！
View PDF, PSD, XLS, XLSX, DOC, DOCX, PPT Online for Free
A friend of mine called me thе other day asking how they соuld quickly view a PowerPoint presentation оn their comрυter without using Office, since they didn’t have that іnstalled. I told her not to wоrry because there are many ways to view Office files without actually needing Оffice.
Thanks to Google and cloud computing in general, nowadays you have fully functional office productivity suites that you can run straight from your browser. Once Google came out with Google Docs, Sheets and Slides, it kind of forced Microsoft to rethink their whole Office strategy. Now Microsoft has a free version of their Office suite that you can use online to create and edit files.
In this article, I’ll show you a couple of different tools you can use to open PDFs, Microsoft Office files, Photoshop files, etc. for free. Now the main catch here with anything free is that the features are limited. The online Office of Word, for example, let’s you do basic editing tasks, but can’t do any of the more advanced tasks like mail merging or footnotes, etc. However, if you just need to view a file, these solutions will be just fine.
Microsoft Office Online Free
If you’re trying to view an Office document, either Word, Excel or PowerPoint, then the best option is to use Office Online. You just go to www.office.com and sign in with your Microsoft account. That’s the only requirement for using their free tools.
With Office online apps, you get the core Microsoft Office apps: Word, Excel, PowerPoint and OneNote. You won’t be able to use these tools to view an Access database, a Visio diagram, or a Microsoft Project file, however.
For the core apps, you can create new files, which will automatically be stored in your OneDrive folder or you can upload new documents from your local computer.
As you can see from below, the online version of Word doesn’t have all the tabs that the ribbon interface on the full version of Word has. It’s missing References and Mailings completely. Also, all the other tabs only have a few of the essential options, but the rest are missing. For most people, the free version is enough, but that’s why Microsoft has Office 365 subscriptions for those who need all the functionality.
The same information applies to the online versions of Excel and PowerPoint also. Great for viewing Office files, good for editing, but not fully functional. Overall, you should give them a try if you need to view and make simple edits to Office files.
Google Docs, Sheets, Slides and Drive
In addition to Office online, Google’s set of online tools can open Microsoft Office files too. So if you are in the Google ecosystem and just need to view some MS Office documents, try opening them in Google Docs, Google Sheets or Google Slides.
I opened my fully formatted resume in Google Docs and it looked exactly like the one in Word! I was then able to edit it as needed without any issues. I also could save the file back into Word format from Google Docs.
What I like about all of the Google tools is that they support add-ons, which can add a lot of functionality to the basic program. So Google Docs, for example, can handle citations and bibliographies using add-ons, which Office online doesn’t support.
If you need to open a PDF file, you can just use Google Chrome instead of downloading a free PDF reader. For just viewing and printing, Google Chrome is a great choice. Just drag and drop the PDF into an open tab in Chrome to view the PDF file.
If you need to view other files types with different extensions, I suggest you try using Google Drive. Google Drive can be used to view Adobe Photoshop files and a whole bunch of other files that normally require a specific application. You obviously can’t edit the PSD file or anything like that. If you wanted to do that, you need other programs like GIMP or Paint.NET. However, for viewing a file, Google Drive is great.
Even though these tools have been around for a while, you may not have known about all the different functions they can perform. Both companies are always adding new features too, so it’s a good idea to check them out now if you haven’t in a long time. Enjoy!
