In spreadsheet documents you can find text, formulas, and styles. You can navigate from one result to the next, or you can highlight all matching cells at once, then apply another format or replace the cell contents by other content.

Cells can contain text or numbers that were entered directly as in a text document. Cells can also contain text or numbers as the result of a calculation. The search method depends on the type of data you are searching for.

By default, Calc searches the current sheet. To search through all sheets of the document, click More Options, then select Search in all sheets option.

Cell contents can be formatted in different ways. For example, a number can be formatted as a currency, to be displayed with a currency symbol. You see the currency symbol in the cell, but you cannot search for it.

Use Replace All with caution; otherwise, you may end up with some highly embarrassing mistakes. A mistake with Replace All might require a manual, word-by-word search to fix, if it is not discovered in time to undo.
