1.How to convert column list to comma separated list in Excel?

Dim rng As Range
Dim InputRng As Range, OutRng As Range
xTitleId = "KutoolsforExcel"
Set InputRng = Application.Selection
Set InputRng = Application.InputBox("Range :", xTitleId, InputRng.Address, Type:=8)
Set OutRng = Application.InputBox("Out put to (single cell):", xTitleId, Type:=8)
outStr = ""

2.How to quickly apply formula to an entire column or row with/without dragging in Excel?
here I recommend copy the formula and then select a starting cell and scroll to the last cell you want to apply and hold down shift+select the last cell, paste, because for excel’s nature of infinite scrolling in vertical direction, if you do fill down to apply formula, it may apply to lots of empty cells you don’t want to apply to, that will cost high memory usage, and in some case excel may get crashed. https://www.extendoffice.com/documents/excel/867-excel-apply-formula-to-entire-column-row.html How to remove prefix / suffix from multiple cells in Excel? https://www.extendoffice.com/documents/excel/2915-excel-remove-prefix-suffix.html

4.Find mismatch value comparing two column
IF(ISERROR(MATCH(E2,$C$2:$C$13363,0)),”na”,E2) Multiple columns: =IF(ISERROR(AND(MATCH(A2,$H$2:$H$46,0),MATCH(B2,$I$2:$I$46,0))),”na”,L2)

7. Match Index
quickly find corresponding values based on comparing the other columns. =INDEX($F$2:$F$100,MATCH(C2,$E$2:$E$100,0)) http://www.excel-university.com/how-to-return-a-value-left-of-vlookups-lookup-column/
如果需要match multiple columns，比如 H1 MATCH A1 同时 I1 MATCH B1，可以先生成临时column：M1=A1&B1 ,N1=H1&I1 =INDEX(T:T,MATCH(M1,N:N,0))
8.Transpose/convert multi column to single column

method 1: import as csv, select the column, change the type to text method 2: Text() https://www.extendoffice.com/documents/excel/2476-excel-convert-date-to-text-or-number.html
12 group by sum
https://www.extendoffice.com/documents/excel/4970-excel-sum-by-group.html =IF(A2=A1,”“,SUMIF(A:A,A2,B:B)), (A2 is the relative cell you want to sum based on, A1 is the column header, A:A is the column you want to sum based on, the B:B is the column you want to sum the values.) Press Enter key, drag fill handle down to the cells to fill the formula.
problems:
to prevent possible loss of data excel cannot shift non-blank cells off of the worksheet
remove the formats
before copy paste, make sure that you want to copy the function or value only, otherwise excel by default will apply functions if you have to all cells you paste to, that will cost much longer time and more memory
