Entering a Number with Leading Zeros

There are various ways to enter integers starting with a zero:

• Enter the number as text. The easiest way is to enter the number starting with an apostrophe (for example, '0987). The apostrophe will not appear in the cell, and the number will be formatted as text. Because it is in text format, however, you cannot calculate with this number.

• Format a cell with a number format such as \0000. This format can be assigned in the Format code field under the Format - Cells - Numbers tab, and defines the cell display as "always put a zero first and then the integer, having at least three places, and filled with zeros at the left if less than three digits".

If you want to apply a numerical format to a column of numbers in text format (for example, text "000123" becomes number "123"), do the following:

1. Seleccione a columna na que se atopan os díxitos en formato de texto. Estabeleza o formato de cela desa columna como «Número».

2. Escolla Editar — Localizar e substituír.

3. Na caixa de diálogo Atopar, introduza ^[0-9]

4. Na caixa de diálogo Substituír, introduza &

5. Marque Expresións regulares

6. Marque Só selección actual

7. Prema en Substituír todo
