Which option provides the least extraction of content when processing Excel files?

The option that provides the least extraction of content when processing Excel files is "Do not extract." This option effectively means that no data or content from the Excel files will be extracted or analyzed at all.

When working with data processing, the action of extraction refers to retrieving certain content from a source, such as an Excel file. The other options listed indicate various methods of extracting content, whether it's placing the extracted data at the end, inline, or at the start of a document. Each of these methods involves some level of data retrieval and placement, meaning they are actively extracting content from the original file.

Choosing to "not extract" signifies a complete disregard for the data within the Excel file, resulting in no information being utilized or altered. Therefore, it stands out as providing the least extraction of content.
