Zellwerten

Zellwerten, literally “cell values,” refer to the data stored in individual cells of a grid-based data structure, such as a spreadsheet, a database table, or a matrix. A Zellwerten may be entered by a user, generated by a formula, or derived from a data import. The value is associated with a specific cell coordinate or index, such as A1 in a spreadsheet or row and column positions in a table.

Zellwerten can take several data types: numeric values (including integers and floating-point numbers), text strings, dates and times, boolean values, and error indicators. Some systems distinguish between a blank cell and a cell containing an empty string. In spreadsheets, the displayed value may differ from the stored underlying representation; dates are often stored as serial numbers.

Many systems allow Zellwerten to be computed using formulas that reference other cells. Relative references adjust when copied, while absolute references fix a particular cell. Ranges of cells can be processed as a unit in functions such as sums or averages. When a referenced cell changes, dependent Zellwerten may automatically update, creating a dependency graph. Circular references are typically disallowed or warned.

Data integrity issues include missing values, inconsistent data types, and locale-specific formatting. Locale affects date formats, decimal separators, and thousand separators, which can influence data import, parsing, and display of Zellwerten. In programming contexts, Zellwerten appear as elements of arrays or data frames, accessible by indices.
