<title>Shuffling Data</title>
<para>
With data shuffling tool you can shuffle data in a given cell
range. The tool can be started by selecting ``Shuffle'' menu
item in ``Data'' menu. In order to use the tool give the input
range in which the data to be shuffled is stored. The tool is
able to shuffle the contents of the whole cell range, or, also
shuffle data according to rows or columns. The shuffling method
is selected under the ``Input Range'' entry. For example, if
your data is grouped by rows then select ``Shuffle Method''
``Rows''.
</para>
<para>
The default output method is to shuffle in-place. The shuffled
data can also be written into a new sheet, new workbook, or into
an existing sheet by giving the output range. If you select the
``Autofit Columns'' option, the width of each output column is
automatically fixed according to the size of data in it.

<sect2 id="sect-data-modify-filter">
<title>Filtering Data</title>
<para>
With data filters you can select a subset of rows in the
worksheet that meet the given criteria. You can, for example,
copy rows of a table containing sales of departments whose
profit has been exceptionally high into a new sheet simply using
a filter.</para>

<para>
To use advanced filter, you should have a few blank rows
available in your worksheet to be used as a criteria range.
These rows should not overlap with the rows in the table to be
filtered.
</para>
<para>Now copy all the column labels from the table you want to
filter into the first blank row in the criteria range. Below the
criteria labels, you can now type the conditions you want to
match for the particular label. For example, under a label
`Profit' you could type `>=1000'. The tool selects only rows
that match all the criteria.</para>

<para>It is possible to have many conditions for a single label.
For example, you can select the departments whose profit is
either very high or very low. To do this, type, for example,
<![CDATA[ `<=0' below the `>=40000' ]]> condition.</para>

<para>``Filter in-place'' writes the new table in-place. Note
that you will loose all the rows in the table that will not match
the criteria. ``Copy to a new location'' copies the selected
rows into the same sheet but into the specified cell range. Type
the cell range into the ``Copy to'' entry if you want this action
to happen. The other options let you to copy the selected rows
into a new sheet or a new workbook.</para>
<para>You should then specify the cell range containing the table
to be filtered in the ``List range'' entry. The cell range
containing the criteria is specified in the ``Criteria range''
entry. If the original table contains duplicate rows, you may
also want to specify the ``Unique records only''. If it is
checked on, the filter removes all duplicates.</para>
<para>To start the tool, you can then click the ``OK'' button and
you will get the new table.</para>
