There are a lot of different resources available for Microsoft Excel training. You can find training on how to use all parts of Microsoft excel as well as very specific training on how to use certain parts of Microsoft excel. There are many different excel professionals that provide training and tips about using excel. You can do a lot with excel but most people don’t know how to use certain functions.

The individuals in your company that use excel may have different skill levels and this can make getting a project done difficult as you will need to train different individuals and this can cause problems with productivity. By having everyone on the same skill level you will find it is much easier to complete all of your projects.

By training all of your staff you can ensure that everyone can use all the functions of excel and complete the project and increase productivity.

If you don’t have a seminar in your future then there are several online courses on how to use excel. The time length of these courses last from 30 to 60 minutes. The online topics you can find courses are filtering external data, excel macros, importing text files into excel, creating charts, different printing options and other excel features.

There are also many Microsoft excel training guides that come in the form of books or as tutorial Cds. You can even find texts on how to become certified as a Microsoft excel specialist.

Some additional and more advanced training can be found for analyzing data and other content, how to manage workbooks, creating data and formatting content and data.

The writer of this article is a developer and trainer with TrainingCompany.Com, a UK IT training company offering Microsoft Excel 2007 Classes at their central London training centre.

One of the pivotal components of the Microsoft Office 2007, Excel is a uniquely powerful spreadsheet. If you bought this sophisticated piece of software, it makes sense to ensure that your staff members know how to use it effectively. Having allowed them a week or two to get used to the new environment and go through some online tutorials, you will probably want to get them properly trained. Tutor-led software training has the benefit that delegates are able to ask questions as they learn and have complex concepts explained and demonstrated to them until they fully understand them.

Sending your people on a public Excel course is one possibility. However, increasingly companies are demanding to have this training customised to meet their specific demands. Microsoft Excel can be used for a variety of data analysis and storage tasks: not everyone uses it in the same way. Perhaps you will be using it for complex business modelling. Or, you may be using it to create interactive forms and reports complete with complex calculations. Maybe your staff will be using the program in a database role recording information under column headings. Booking a customised course will ensure that you only pay for instruction which is relevant to your requirements and reflects the way in which you will be using Microsoft Excel.

Before you start contacting Excel training companies, it would be a good idea to ensure that you have a clear idea of what you want to achieve by using Excel and that your expectations are realistic. When you approach training companies, you should make it clear that you do not simply want them to deliver their standard Excel courses but that you require a customised programme of training. Between you, a schedule of topics to be covered should then be drawn up and the duration of the program decided.

The customisation process may also involve identifying different requirements within your own organisation. Different people may need to do different tasks with the program and therefore need different skills. For example, some of your users will be primarily interested in using Excel for business analysis and projection. Their primary areas of interest will be the “What if” analysis tool like goal seek, scenarios and pivot tables. On the other hand, you may have people who are interested in create charts and reports either for printing or for use in PowerPoint presentations.

Most training companies offering customised Excel courses should be willing to accommodate the specific needs of your organisation and the different profiles of the staff members: accounts, sales and marketing, etc. Between you, you can then create a program of study which satisfies the needs of all users. Perhaps this may mean, having different courses for users with different profiles or perhaps the best approach will be a modular one whereby some modules are taken by everyone while others are only attended by certain user groups.

XML schema definition languages are derived from the recommendations of the World Wide Web Consortium (W3C). They use XML 1.0 syntax and their role is to explicit describe the structure of XML documents and constrain the data which they may contain. They offer a distinct improvement on the more limited schema features offered by the Document Type Definition (DTD) recommendation which formed part of the original XML specification released in 1998. The most widely used schema language is the one defined by the W3C in 2001: W3C XML Schema. However, there are alternatives, such as RELAX NG and Schematron.

Schema documents are the more sophisticated successors to DTDs and overcome some key limitations associated with them. Firstly, DTDs do not support data types. Secondly, DTDs do not support namespaces. Thirdly, DTDs do not allow developers to accurately define the number of permitted occurrences of elements within their parent element.

An XML schema describes the structure of an XML instance document by defining what each element must or may contain. An element is limited by its type. For example, an element of complex type can contain child elements and attributes, whereas a simple-type element can only contain text. The diagram below gives a first look at the types of XML Schema elements.

Schema documents have three main purposes. Firstly, they can be used to validate XML documents. Secondly, they can be used as a dictionary or grammar for the creation of a given class of XML document. And, thirdly, they can be used to provide documentation for XML documents.

Each XML schema is itself an XML document and contains definitions of all elements and attributes permitted in a given class of XML documents. The schema also specifies the structure or hierarchy to which elements must adhere and the type of content each particular element may contain. Elements may be of the simple or complex type. Complex type elements may contain child elements as well as attributes. Simple type element may only contain data. XML documents using a particular schema are referred to as instances of the schema. An XML instance that correctly adheres to its associated schema is said to be valid.

Validation is usually the main purpose of schema documents. Validation offers many benefits. It ensures the consistency of data within a document. It ensures that data has the right structure and internal hierarchy. It ensures that data within the document structure is of the correct type. It allows us to receive data from multiple sources.

Almost all XML documents are generated by programs and scripts written to extract information held in databases and transform it into XML. However, it is also possible for human beings to create XML documents. Schemas can be used during this process to assist in the document creation process. XML schemas also provide a mechanism for documenting XML documents and form an important part of the specification of XML vocabularies.

The Mini toolbar is a floating palette which automatically appears when you highlight text. Initially all the options it contains are discreetly dimmed. However, when you position the cursor over its controls, the Mini toolbar becomes activated.

It offers a selection of handy options for formatting your text. All of these options can equally be found in the Home tab of the Word Ribbon. The top row of Mini toolbar icons allows you to change the font, size and colour of our text and also contains Word’s nifty Format Painter. Word’s Format Painter tool allows you to copy the format of the selected text to other areas of your document.

The second row of the Mini toolbar has buttons for making text bold, italic, centre aligned. It also has tools for changing the colour of the highlighted text, indenting text and converting your text to bullet points.

The Mini toolbar offers a very convenient way of quickly formatting your text without having to go back to the Ribbon to find the options you’re looking for. However, there are times when it can be inconvenient. This is particularly true when using the drag-and-drop facility within Microsoft Word.

This feature allows you to highlight text and simply drag it to a new location. However, just as you are about to drag, it’s very easy for the cursor to collide with the Mini toolbar and instead of dragging your text, you simply change its format.

As a Word user, you’ll decide whether you like the Mini toolbar facility. If you decide it is more trouble than it’s worth, Word allows you to deactivate this facility. From the Office button, choose Word Options. In the Popular category, the very first option is “Show Mini Toolbar on selection”. If you have had enough of the Mini toolbar, simply deactivate this option. Now, whenever you highlight text, the Mini toolbar will not appear.

Even when you have asked Word not to display the Mini toolbar, it is still possible to show it by simply right-clicking on selected text.
