Stability —
Gnumeric has undergone
significant amounts of testing with a diverse group of
users. There is also a large set of test workbooks to
validate the quality of the importers. This release can be
considered safe for use in a production environment.
File compatibility —
Transparent access and manipulation of files from other applications
is vital in a modern office. Gnumeric can
read files from several well known proprietary and free spreadsheets
including MS Excel (tm), Lotus 1-2-3 (tm), Applix (tm), Psion, Sylk,
XBase Oleo, and HTML. It can also export to MS Excel (tm) along with
several open formats such as LaTeX \longtables, HTML, roff. Rounding
out the i/o routines is a highly configurable text importer/exporter
to ensure that data can be transfered smoothly. New formats can
easily be added in a modular fashion via a plug-in.
Minimal cost of transition —
Learning new and unfamiliar interfaces is an expensive and frustrating
process. Gnumeric attempts to offer
optional extensions and enough compatibility that a user's
familiarity with other applications will still apply.
Sufficient feature set —
While people may quote the statistic that most users only need 20% of
the features in some products that is not entirely true. Most need a
common 10% and then some non-overlapping collection for the other 10%.
Implementing enough of the features to support day to day use by the
average spreadsheet user has taken time. However, just having the
feature listed as a bullet point does little for a user.
Gnumeric has attempted to only provide
full implementations of the features it offers, preferring to leave a
feature out, rather than provide something that is only useful in a
screen-shot.
Internationalization —
Gnumeric has been translated into 29
languages, and is being used by people around the globe in their
native locales.
Openness and Scalability —
Gnumeric is free
software released under the
GNU
GPL. It's core architecture has also seen a lot of design work
to ensure that it can comfortably scale to moderately large loads (1M
cells) while remaining usable on older hardware. The availability of
clean reasonably documented source makes it simple to do things like
change the maximum size of a sheet.
The best way to learn how to use
Gnumeric is to begin exploring the
program yourself. Enter some data into cells by clicking on the
cell, typing a number and hitting
return. Gnumeric supports
different kinds of data such as numbers, dates, currency and
text by formating each kind of data differently and by
calculating results appropriate to each data type. To learn more
look at Chapter 6.
Write a formula by clicking on an empty cell, typing the equals key,
clicking on a second cell that has a number, typing the minus key, typing
2 and hitting return. The number you see should be the number in the
second cell minus two. Try changing the number in the second cell and
watch Gnumeric automatically re-calculate the
result. For more powerful functions see Section 6.2 later in this manual.
You can format the data, by changing the text color, adding borders and
changing the placement. Explore the bottom toolbar and the menu that
opens when you click on a cell with the rightmost mouse button. Look at
Chapter 9 later in this manual.

Gnumeric, read this manual, visit the

ask friends who use spreadsheets or read a book on how to use MS
Excel (tm).
