Modifier les métadonnées Excel en C#

Editing Excel metadata programmatically using C# and IronXL allows developers to seamlessly update or manipulate workbook properties, such as author, title, subject, or custom metadata fields, without manual interaction. This feature is particularly beneficial in scenarios involving automated workflows, large-scale data processing, or integration with other systems, such as SQL databases.

IronXL makes this process efficient by supporting popular Excel formats like XLSX, XLS, and CSV. This functionality minimizes manual effort and ensures accuracy for teams dealing with reporting, auditing, or metadata-driven applications. It simplifies the integration between Excel files and backend systems, enabling dynamic, metadata-centric solutions that scale effectively in real-world enterprise environments.
