    Savvy DOCX Recovery

    Savvy DOCX Recovery

    Open corrupt Word DOCX files and possibly recover formatting too.

    XML was designed from the beginning to be intolerant of errors. This decision adversely affects MS Word's corruption recovery. With one error in the document.xml subfile where all the DOCX file's text is stored, instead of a partial recovery, Word will stop and throw an error. Savvy DOCX Recovery attempts to do precise surgery on corrupt Word documents to reorder or excise bad XML tags. If this doesn't work, it uses the command line app xmllint first to attempt to repair corrupt XML subfiles of the DOCX. If this doesn't work a second attempt is made where the corrupt XML subfiles are truncated at the first error, and the correct ending tags are again added with xmllint. If all else fails, SilverCoder's DocToText is used to extract text. Try also http://wordcorruptdocchecker.codeplex.com/ and https://support.microsoft.com/en-us/kb/2528942 and my other SF projects: Corrupt Extractor for Microsoft Office, Corrupt DOCX Salvager, S2 Recovery Tools for Microsoft Word.

Guide to Open Source Office Suites

Open source office suites are a great alternative to expensive, commercial word processing, spreadsheet, and presentation software. They provide a wide range of tools and applications necessary for creating professional-looking documents, spreadsheets, presentations and more. They are available in both desktop version as well as web versions which can be accessed through any internet connection.

Open source office suites offer many attractive features compared to other office suites such as Microsoft Office or Apple iWork Suite. One major benefit is the cost savings, since you don’t have to pay for expensive licenses for each computer running the software, nor do you have to purchase multiple copies of CDs or downloads from different companies. In addition, open source software often has more features than its commercial counterparts at no additional cost – which can be very desirable if you need extra capabilities not found in your current suite. The source code is also publicly available so that users can customize the programs to suit their individual needs better than with closed-source options like MS Office or iWork Suite. This means that potentially anyone could download the code and modify it for their own specific uses without having to pay an additional fee or royalties - something that isn't possible with proprietary programs.

Another major advantage of most open source office suits is cross compatibility between different operating systems and devices with less effort involved on the user side; they don’t require separate versions of program files or document formats for Windows PCs versus Macs like most proprietary products do. Additionally, because there is much more public input into these projects than closed-source ones, many bugs are quickly identified and resolved by developers along with faster implementation of desired features from users - making them much less customizable but also generally easier to use than programs written by only one corporate entity working on updates only when they deem fit. Open Source projects are created by large teams giving them access resources larger corporations may not have yielding higher quality results faster then traditional methods due to accelerated development cycles & collaborative nature behind every project released under such licenses as GNU GPL (General Public License).

Overall open source office suites offer a huge amount of value over their propriety competitors while remaining free & accessible across platforms creating a level playing field regardless of hardware used or software installed allowing everyone access without limitations otherwise imposed by traditional methods leaving it up user choose how best utilize what’s offered at no financial cost not hindrance whatsoever granting freedom unlike seen before in history technology where we now stand together looking ahead towards future near brighter then ever before thanks team effort enabled by driven enthusiasm community members everywhere standing start all ages abilities backgrounds united cause shared common goal success.
