How I can create 3 subscripts after a variable? - mathjax

I have
\over E_max - E_min
but it doesn't display all of them as a subscript, just the first m after the E_

Put the subscripts in curly braces so that all three characters are included.
\over E_{max} - E_{min}

Excel Formula To Replicate Text To Column Functionality

I would like a formula in excel that does what Text To Columns does.
For example the following string in A1
" text with a comma, stays in one column",," keep starting blank text",1,2,3,"123"
Would be split into multiple cells like this...
The following LET Function allows you to split the text into columns based on the splitter character (in this instance a comma).
It ignores commas that are between quotes (the Delim argument - which has double quotes in it).
It does this by ensuring there is an even number of quotes before the splitter character.
=LET(
NOTES,"Splits a string but also checks to see if the splitter is inside a delimiter. So will ignore a comma inside quotes.",
RawString,$A1,
Splitter,",",Note2,"This is the character to split the string by",
Delim,"""",Note4,"This is the text delimiter it looks odd but it's just a double quote - change to "" if you don't want text delimitation",
IgnoreBlanks,FALSE,
CleanTextDelims,TRUE,
TrimBlanks,FALSE,
SplitString,Splitter&RawString&Splitter,Note3,"Add the splitter to the start and the end to help create the array of split positions",
StringLength,LEN(SplitString),
Seq,SEQUENCE(1,StringLength),Note5,"Get a sequence from 1 to the length of the split string",
Note6,"The below does the bulk of the work. It works out if we are at an odd or even point in terms of count of text delimiters up to the point in the sequence we are processing.",
Note7,"if we are at an even point and we have a delimiter then make a note of the sequence otherwise put a blank.",
PosArray,IF(Seq=StringLength,Seq,IF(MOD(LEN(LEFT(SplitString,Seq))-LEN(SUBSTITUTE(LEFT(SplitString,Seq),Delim,"")),2)=0,IF(MID(SplitString,Seq,1)=Splitter,Seq,""),"")),
PosArrayClean,FILTER(PosArray,PosArray<>""),Note8,"Clean blanks",
StartArray,FILTER(PosArrayClean,PosArrayClean<>StringLength),
EndArray,FILTER(PosArrayClean,PosArrayClean<>1),
StringArray,MID(SplitString,StartArray+1,EndArray-StartArray-1),
StringArrayB,IF(IgnoreBlanks,FILTER(StringArray,StringArray<>""),StringArray),
StringArrayC,IF(CleanTextDelims,IF(LEFT(StringArrayB,1)=Delim,MID(StringArrayB,2,IF(RIGHT(StringArrayB,1)=Delim,LEN(StringArrayB)-2,LEN(StringArrayB))),StringArrayB),StringArrayB),
IFERROR(IF(TrimBlanks,TRIM(StringArrayC),StringArrayC),"")
)
Breaking down each step in the LET formula:
Supply the raw string (from cell A1 in this case)
Set the splitter character - in this case a comma
Set the text delimiter - in this case double quotes (looks odd because it has to be as double double quotes - Delim,"""" )
IgnoreBlanks is an option to exclude blank cells in the output
CleanTextDelims will clean the TextDelimiter (Double quotes) from the start and end of the resultant string
Create a SplitString variable with the split character at the front and back.
Get the length of the string for ease of use
Get a sequence from 1 to the length of the string.
Get an array of the position of characters that are splitters with an even number of Text Delimiters to the left of that position in the string the posArray (splitter position array).
Clean the blanks to get the posArrayClean
Create a start and end array (start array ignores the last and end array ignores the first item in the PosArrayClean)
Get the array of strings/cells to output.
If the IgnoreBlanks is used then igore blank cells
If the CleanTextDelims option is set then strip off the Text Delim (double quotes) from the start and end of the resultant string.
If the TrimBlanks option is set then trim blank spaces off the start and end of the resulting strings.
Hopefully the notes explain clearly how this works and make it easy to modify.
If you want create a named Lambda to use you can use the following code to paste into the formula of a named range called SplitStringDelim (you can name it what you like of course). NB You can't have the line separators in this and I stripped the notes out of it.
=LAMBDA(StringRaw,SplitChar,DelimChar,IgnoreBlank,CleanTextDelim,TrimBlank, LET( RawString,StringRaw, Splitter,SplitChar, Delim,DelimChar, IgnoreBlanks,IgnoreBlank, CleanTextDelims,CleanTextDelim, TrimBlanks,TrimBlank, SplitString,Splitter&RawString&Splitter, StringLength,LEN(SplitString), Seq,SEQUENCE(1,StringLength), PosArray,IF(Seq=StringLength,Seq,IF(MOD(LEN(LEFT(SplitString,Seq))-LEN(SUBSTITUTE(LEFT(SplitString,Seq),Delim,"")),2)=0,IF(MID(SplitString,Seq,1)=Splitter,Seq,""),"")), PosArrayClean,FILTER(PosArray,PosArray<>""),Note8,"Clean blanks", StartArray,FILTER(PosArrayClean,PosArrayClean<>StringLength), EndArray,FILTER(PosArrayClean,PosArrayClean<>1), StringArray,MID(SplitString,StartArray+1,EndArray-StartArray-1), StringArrayB,IF(IgnoreBlanks,FILTER(StringArray,StringArray<>""),StringArray), StringArrayC,IF(CleanTextDelims,IF(LEFT(StringArrayB,1)=Delim,MID(StringArrayB,2,IF(RIGHT(StringArrayB,1)=Delim,LEN(StringArrayB)-2,LEN(StringArrayB))),StringArrayB),StringArrayB), IFERROR(IF(TrimBlanks,TRIM(StringArrayC),StringArrayC),"")))

Is there a way to add leading/trailing spaces to item in concatenate function?

I am trying to bring together several cells and they have a specific length so if I have
A1 needs to be 5 chars and the value is 'cat'
B1 needs to be 6 chars and the value is 'dog'
Concatenated it would be:
[space space]cat[space space space]dog
or
" cat dog"
I'm having trouble finding a function or set of functions that allows this, most want to trim out leading or trailing spaces.
Yes:
=CONCATENATE(RIGHT(REPT(" ",5)&A1,5),RIGHT(REPT(" ",6)&A2,6))
or as #BigBen stated use & instead of Concatenate:
=RIGHT(REPT(" ",5)&A1,5)&RIGHT(REPT(" ",6)&A2,6)

Remove all text and characters except some

I have here some text strings
"16cg-301 -request","16cg-3368 - for review","16cg-3684 - for process"
what i would like to do is to remove all the text and characters except the number and the letters "cg" and - which is within the reference code.
If the string you want to extract is always before the first space in the full string then you can use SEARCH and LEFT to extract your reference code:
=LEFT(A1,SEARCH(" ",A1)-1)
This formula would take 16cg-3368 from 16cg-3368 - for review.
I suggest using something like suggested here
How to use Regular Expressions (Regex) in Microsoft Excel both in-cell and loops

only works by now for less than 33 signs.
problem here will be that you will get unexpected behavior like this:
123cg-123 - Process => 123cg-123-c
after rereading , I think you should try an other approach than described in the question ;-)
If you want to return everything up to and including the last digit, then try:
=LEFT(A1,LOOKUP(2,1/ISNUMBER(-MID(A1,seq,1)),seq))
seq is a named formula: Formula ► Define Name
Name: seq
Refers to: =ROW(INDEX($1:$65535,1,1):INDEX($1:$65535,255,1))
seq returns an array of sequential numbers from 1 to 255.
mid(a1,seq,1)
returns an array consisting of the individual characters in the string in A1. The leading minus sign converts the digits from strings to numbers.
The lookup function will then return the position of the last digit

Excel - remove characters after a specific character

I have colum B with values:
0015-04D-SEAW
0015-ADLKM-SPOK
0015-D-CURR
0016-01N-BOIL
etc.
How can I remove all characters after second dash and the second dash itself as well, it should look like this:
0015-04D
0015-ADLKM
0015-D
0016-01N
Assuming B1 contains 0015-04D-SEAW
This would do : =IFERROR(MID(B1,1,FIND("-",B1,FIND("-",B1,1)+1)-1),B1)
Result : 0015-04D
One dirty solution would be to convert text to columns delimited by - and then to concatenate the first two columns separated by -

How to wrap a range of hex data with quotation mark?

I want to wrap a hex number with quotation mark as I hit the enter.
12bc >> '12bc'
I used such a format type: '#', but it works only for numbers, not the a combination of numbers and alphabets containing a hex string.
For the sake of an answer, courtesy #lori_m:
Try this: '#'
