What happens if you merge records without specifying any columns?

When merging records without specifying any columns, the system combines all the records from the component worksheets. This means that every entry from each worksheet included in the merge operation is displayed in the resulting composite worksheet. The merging process does not filter out any records, regardless of whether columns that could serve as unique identifiers are involved.

In situations where no specific criteria or columns are designated for merging, the default behavior is to compile a comprehensive list that comprises all data from the participating worksheets. This allows a complete overview of the merged datasets, making it particularly useful for analysis or review when the intention is to see all available data without restriction.

Understanding how this process works is crucial for effective data management, as it highlights the importance of defining criteria when you want to achieve targeted merges or prevent data loss.
