Excel 2008 helps you manage your data for powerful results, visually persuasive charts, and thought-provoking graphs.
Ledger sheets in Excel 2008 make tracking finances, inventories, invoices, and even portfolios easy with preformatted spreadsheets and automatic calculations.
Ledger sheets
Use these preformatted Excel spreadsheets to balance your checkbook, track an investment portfolio, create an expense report, and perform other common tasks. Each ledger sheet addresses a specific scenario. For example, if you open an invoice ledger sheet, the sheet contains all of the formulas and columns appropriate for tracking and managing invoices.
Formula Builder
The Formula Builder helps you create formulas in a simple, step-by-step approach. You don’t have to memorize functions or their syntax. Use it to create formulas, search for functions, insert functions and arguments in existing formulas, and get help on all Excel functions.
Formula AutoComplete
Write and edit formulas without having to remember function names, defined names, or other elements of a formula. When you type a formula in a cell, you can choose valid functions, names, and named ranges in context.
Improved charting
Create modern-looking charts by using new charting templates and tools that include special effects such as 3-D, transparency, and shadows. You can preview and insert any chart directly from the Charts tab in the Elements Gallery. After you create a chart in Excel, you can use it in other Office documents.
File Formats
Excel 2008 documents are saved as Office XML files (.xlsx files). Older versions of Excel are not compatible with Excel 2008 and should detect when you first try to open a .xlsx file, then prompt you to download and install a document conversion pack. After you have done this, the older Excel should convert your Excel 2008 files and remove incompatible features. When you reopen that same .xlsx file again in Excel 2008, the file’s original elements should stay intact. If you open an older .xls file with Excel 2008, it will run in Compatibility Mode, shutting off access to some of the newer program features; therefore, two documents within Excel 2008 may display different formatting options.
