I'm curious if there is a more efficient way to code this. I ingest data from ~25 files; each with people's names formatted differently (sometimes w/in the same file). I cannot control the format of the files I get, so I'm having to use code to get the names in the format I want. I feel like there has to be a more efficient way to do this:
VBA Code: 
Sub IDDecisionerNames()

Application.DisplayAlerts = False
Application.ScreenUpdating = False

Dim m As Workbook
Dim mD As Worksheet, mV As Worksheet
Dim mDLR As Long
Dim c As Range

Set m = ThisWorkbook
Set mD = m.Sheets("Data")
Set mV = m.Sheets("Variables")

mDLR = mD.Range("C" & Rows.Count).End(xlUp).Row
mVLR = mV.Range("A" & Rows.Count).End(xlUp).Row

'mD.UsedRange.Sort Key1:=Range("G2"), Order1:=xlAscending, Header:=xlYes

'******Prep Decisioner Lookup Columns******

mD.Range("H2:H" & mDLR).Value = "Pending Calc"

'Last, Pref First
mV.Range("O2:O" & mVLR).Value = "=IF(RC[-11]="""","""",RC[-9]&"", ""&RC[-11])"

'Last, Pref First & MI
mV.Range("P2:P" & mVLR).Value = "=IF(OR(RC[-11]="""",RC[-12]=""""),"""",RC[-10]&"", ""&RC[-12]&"" ""&LEFT(RC[-11],1))"

'Last, Legal First
mV.Range("Q2:Q" & mVLR).Value = "=RC[-11]&"", ""&RC[-14]"

'Last, Legal First & MI
mV.Range("R2:R" & mVLR).Value = "=IF(RC[-13]="""","""",RC[-12]&"", ""&RC[-15]&"" ""&LEFT(RC[-13],1))"

'Legal First & Last
mV.Range("S2:S" & mVLR).Value = "=PROPER(RC[-16])&"" ""&PROPER(RC[-13])"

'Middle & Last
mV.Range("T2:T" & mVLR).Value = "=IF(LEN(RC[-15])>1,RC[-15]&"" ""&RC[-14],"""")"
'Holder2
'Holder3
'Holder4
'Holder5
'Holder6
'Holder7
'Holder8
'Holder9
'Holder10

'First (Pref then Legal) & Last
mV.Range("AD2:AD" & mVLR).Value = "=IF(RC[-26]="""",PROPER(RC[-27]) & "" ""&PROPER(RC[-24]),PROPER(RC[-26])&"" ""&PROPER(RC[-24]))"

You could make your code much more efficient by using variant arrays, probably 1000 times faster:
One of the main reasons that Vba is slow is the time taken to access the worksheet from VBa is a relatively long time.
To speed up vba the easiest way is to minimise the number of accesses to the worksheet. What is interesting is that the time taken to access a single cell on the worksheet in vba is almost identical as the time taken to access a large range if it is done in one action.

So instead of writing a loop which loops down a range copying one row at a time which will take along time if you have got 50000 rows it is much quicker to load the 50000 lines into a variant array ( one worksheet access), then copy the lines to a variant array and then write the array back to the worksheet, ( one worksheet access for each search that you are doing),

I have a simple rule for fast VBA: NEVER ACCESS THE WORKSHEET IN A LOOP.
