Entering numbers as text
If a number is entered in the format
01481
, Calc will drop the leading
0. (Exception: see Tip below.) To preserve the leading zero, for example
for telephone area codes, type an apostrophe before the number, like
this: '01481.
The data is now regarded as text by Calc. Formulas and functions will
treat the entry like any other text entry, which typically results in it
being a zero in a formula, and being ignored in a function.
Tip
Numbers can have leading zeros and be regarded as numbers
(as opposed to text) if the cell is formated appropriately. Right-
click on the cell and chose Format Cells > Numbers. Adjust
the leading zeros setting to add leading zeros to numbers.
Note
When using an apostrophe to allow a leading 0 to be displayed,
the apostrophe is not visible in the cell after the
Enter
key is
pressed—
if
the apostrophe is a plain apostrophe (not a “smart
quote” apostrophe). If “smart quotes” are selected for
apostrophes, the apostrophe remains visible in the cell.
To choose the type of apostrophe, use Tools > AutoCorrect >
Custom Quotes. The selection of the apostrophe type affects
both Calc and Writer.
Caution
When a number is formatted as text care must be taken that
the cell containing the number is not used in a formula since
Calc will ignore the value.
Entering dates and times
Select the cell and type the date or time. You can separate the date
elements with a slant (/) or a hyphen (–) or use text such as 10 Oct 03.
Calc recognizes a variety of date formats. You can separate time
elements with colons such as 10:43:45.
Speeding up data entry
Entering data into a spreadsheet can be very labor-intensive, but Calc
provides several tools for removing some of the drudgery from input.
The most basic ability is to drop and drag the contents of one cell to
another with a mouse. However, Calc also includes several other tools
for automating input, especially of repetitive material. They include the
