In general, to merge means to combine two or more things together to form a single entity.

In computing, merging refers to the process of combining multiple files or datasets into one. For example, you might merge two spreadsheets in Excel to combine their data into one unified spreadsheet. This can be useful when working with large amounts of data, especially when the data is spread across multiple files or sources.

In version control systems like Git, merging refers to the process of combining changes from two or more branches into a single branch. This is typically done when multiple developers are working on the same codebase and need to collaborate on changes. When a merge is performed, any conflicts between the changes are resolved and the resulting code is tested to ensure that it works as expected.

Merging can also refer to combining multiple cells or ranges in a spreadsheet program like Excel. When cells are merged, their contents are combined into a single cell, and the formatting of the merged cells is applied to the resulting cell. This can be useful for creating titles or headings in a spreadsheet or formatting cells for a specific purpose.
