Power Query enables you to filter and shape the imported data into Excel by editing query steps to match your data analysis requirements, You can perform a wide variety of data analysis steps including, filtering a table, sorting a table, removing columns, and merging multiple tables. For detailed information about shaping your data, see Shape data in the Power Query for Excel Help.
After filtering and shaping the imported data in Excel, you are now ready to share the improved data as query. For more information, see Share Queries.
Important When you share a query, the underlying data itself is not shared. Only the query and the metadata provided by the user are shared. When users search and use a shared query in Power Query, the shared query is run within Power Query to return the data that it references.
