P45cal,
This is the code that I need to "reverse" but I really do not know how


let
Source = Excel. CurrentWorkbook(),
#"Filtered Rows" = Table. SelectRows(Source, each ([Name] = "RegnsNotRenewedThisYear"))
#"ExpandedContent"
#"SortedRows"
#"KeptLastRows"
#"RemovedColums"
I tried inserting "tbl=>" before the let and the "RegnsNotRenewedThisYear" to "tbl" but received an error.
Thank you.

Perhaps some self teaching is required; I can't do it myself but here are some links you can look through:

Thank you for the links. I'm not giving up on this. Meantime, I have to make do with a quite circuitous process but with the same wanted results.
