# Datasheet Window

The Datasheet Window contains Datasheets where you can enter data. A Datasheet takes the form of a spreadsheet and is placed within a tab. By default, a Datasheet has 300 rows (1, 2, …, 300) and 50 columns (C1, C2, …, C50).

The variable row of the table is for the variable names of the columns. Variables names cannot contain characters ' and ", and they cannot be the same for different columns.

A cell in a datasheet can contain both text and numbers. Numbers in data cells are internally stored as double-precision 64-bit IEEE 754 floating point values, even though they are displayed to at most 6 decimal places. The tooltip of a cell shows the precise value stored in a cell.
