A workbook in Microsoft Excel can embody business rules, calculations and recurring tasks. Once other people or processes rely on its results, its operational importance deserves explicit assessment. [When does a spreadsheet become an application?](https://grassroot.it/en/artikel/tabelle-zur-anwendung) explains this distinction.

## Make the structure understandable

The Grassroot framework distinguishes inputs, calculations and outputs clearly. Identify data sources and manual steps. An employee should understand which values may be entered and which results need checking.

Microsoft documents structured references and data validation for tables in Microsoft Excel. These features can support clarity, but input validation does not replace business reconciliation. The [manufacturer’s overview of tables in Microsoft Excel](https://support.microsoft.com/en-us/excel/overview-of-excel-tables) explains the foundations.

## Check the whole workbook

Suitable examples cover valid and unsuitable inputs, missing values and changing data volumes. Include links to other files and any [Visual Basic for Applications automation](https://grassroot.it/en/artikel/vba). Establish expected results independently of the version being developed.

For sustained use, define an approved version, owner and recovery method. [Controlled changes](https://grassroot.it/en/artikel/aenderungen-und-versionen) support orderly introduction of improvements. Permitted product versions and functions depend on the organisation’s actual environment.
