how to reduce list size of a already imported list?

To reduce the size of an already imported list, you can manually remove specific rows from your table. You can also hide columns you don't need by right-clicking a column and selecting Hide, or by clicking columns above the table and toggling columns off. For more precise control, use filters to display only the data you need, then manually delete unwanted rows.

Hi Dipson, Would you want to send the link (url) to the table so I can take a closer look? And provide a little more context on what you're hoping to do?

My first thought would be to use filters to start reducing table size, and then enrich once you have that smaller table. Will look out for your response! Gabe
