Visual Basic for Applications (VBA) extends office applications and can automate recurring processing in Microsoft Excel and Microsoft Access. [Microsoft’s introduction](https://learn.microsoft.com/en-us/office/vba/library-reference/concepts/getting-started-with-vba-in-office) explains getting started and working with application object models.

## Keep processing steps small and understandable

Where useful, Grassroot IT separates business calculations, user interaction and file or data access. Clear names and manageable procedures help a second developer understand the flow. Describe inputs and expected results before checking code against examples.

Error handling should explain which step failed and whether changes have already occurred. For an interrupted import, consider whether running it again could create duplicate records. Correct handling depends on the actual processing.

## Enable changes and approval

The [change record](https://grassroot.it/en/artikel/aenderungen-und-versionen) includes version, reason and business test results. Exported modules can support readable source storage, but the complete runnable application and its dependencies remain necessary.

Complete the intended [testing and approval](https://grassroot.it/en/artikel/pruefung-und-freigabe) before operational use. Respect macro settings and other organisational safeguards. Automation does not justify disabling protection indiscriminately.
