I have a worksheet with products where the people in my office can add new positions. The problem we're running into is that the products have specifications but not everybody puts them in (or inputs them wrong).
Example:
"cool product 14C"
Is there a way to convert Data Valuation option so that it warns me now in case I put "very cool product 14B" or anything that contains an already existing string of characters (say, longer than 4), like "cool produKt 14C" but also "good product 15" and so on?
I know that I can prevent 100% matches using COUNTIF and spot words that start/end in the same way using LEFT/RIGHT but I need to spot partial matches within the entries as well.
Thanks a lot!
If you want to cover typo's, word wraps, figure permutations etc. maybe a SOUNDEX algorithm would suit to your problem. Here's an implementation for Excel ...
So if you insert this as a user defined function, and create a column =SOUNDEX(A1) for each product row, upon entry of a new product name you can filter for all product rows with same SOUNDEX value. You can further automate this by letting user enter the new name into a dialog form first, do the validation, present them a Combo Box dropdown with possible duplicates, etc. etc. etc.
edit:
small function to find parts of strings terminated by blanks in a range (in answer to your comment)
Function FindSplit(Arg As Range, LookRange As Range) As String
Dim LookFor() As String, LookCell As Range
Dim Idx As Long
LookFor = Split(Arg)
FindSplit = ""
For Idx = 0 To UBound(LookFor)
For Each LookCell In LookRange.Cells
If InStr(1, LookCell, LookFor(Idx)) <> 0 Then
If FindSplit <> "" Then FindSplit = FindSplit & ", "
FindSplit = FindSplit & LookFor(Idx) & ":" & LookCell.Row
End If
Next LookCell
Next Idx
If FindSplit = "" Then FindSplit = "Cool entry!"
End Function
This is a bit crude ... but what it does is the following
split a single cell argument in pieces and put it into an array --> split()
process each piece --> For Idx = ...
search another range for strings that contain the piece --> For Each ...
add piece and row number of cell where it was found into a result string
You can enter/copy this as a formula next to each cell input and know immediately if you've done a cool input or not.
Value of cell D8 is [asd:3, wer:4]
Note the use of absolute addressing in the start of lookup range; this way you can copy the formula well down.
edit 17-Mar-2015
further to comment Joanna 17-Mar-2015, if the search argument is part of the range you're scanning, e.g. =FINDSPLIT(C5; C1:C12) you want to make sure that the If Instr(...) doesn't hit if LookCell and LookFor(Idx) are really the same cell as this would create a false positive. So you would rewrite the statement to
...
...
If InStr(1, LookCell, LookFor(Idx)) <> 0 And _
Not (LookCell.Row = Arg.Row And LookCell.Column = Arg.Column) _
Then
hint
Do not use a complete column (e.g. $C:$C) as the second argument as the function tends to become very slow without further precautions

I'm working on a research related to frequencies.
I want to sum all the numbers in each cell and reduce them to single number only.
some cells have 2 numbers, others have 13 numbers. like these..
24.0542653897891
25.4846064424057
27
28.6055035477009
I tried several formulas to do that. the best ones have me 2 digits number, that I couldn't sum it again to get a single result.
like these Formulas:
=SUMPRODUCT(MID(SUBSTITUTE(B5,".",""),ROW(INDIRECT("1:"&LEN(B5)-1)),1)+0)
=SUMPRODUCT(1*MID(C5,ROW(INDIRECT("1:"&LEN(C5))),1))
any suggestion?
Thank you in advance.
EDIT
Based on your explanation your comments, it seems that what you want is what is called the digital root of the all the digits (excluding the decimal point). In other words, repeatedly summing the digits until you get to a single digit.
That can be calculated by a simpler formula than adding up the digits.
=1+(SUBSTITUTE(B5,".","")-1)-(INT((SUBSTITUTE(B5,".","")-1)/9)*9)
For long numbers, we can split the number in half and process each half. eg:
=1+MOD(1+MOD(LEFT(SUBSTITUTE(B5,".",""),INT(LEN(SUBSTITUTE(B5,".",""))/2))-1,9)+1+MOD(RIGHT(SUBSTITUTE(B5,".",""),LEN(SUBSTITUTE(B5,".",""))-INT(LEN(SUBSTITUTE(B5,".",""))/2))-1,9)-1,9)
However, the numbers should be stored as TEXT. When numbers are stored as numbers, what we see may not necessarily be what is stored there, and what the formula (as well as the UDF) will process.
The long formula version will correct all the errors on your worksheet EXCEPT for B104. B104 appears to have the value 5226.9332653096000 but Excel is really storing the value 5226.9333265309688. Because of Excel's precision limitations, this will get processed as 5226.93332653097. Hence there will be a disagreement.
Another method that should work would be to round all of the results in your column B to 15 digits (eg: . Combining that with using the long formula version should result in agreement for all the values you show.
Explanation
if a number is divisible by 9, its digital root will be 9, otherwise, the digital root will be n MOD 9
The general formula would be: =1+Mod(n-1,9)
In your case, since we are dealing with numbers larger than can be calculated using the MOD function, we need to both remove the dot, and also use the equivalent of mod which is n-(int(n/9)*9)
Notes:
this will work best with numbers stored as text. Since Excel may display and/or convert large numbers, or numbers with many decimal places, differently than expected, working with text strings of digits is the most stable method.
this method will not work reliably with numbers > 15 digits.
If you have numbers > 15 digits, then I suggest a VBA User Defined Function:
Option Explicit
Function digitalRoot(num As String) As Long
Dim S As String, Sum As Long, I As Long
S = num
Do While Len(S) > 1
Sum = 0
For I = 1 To Len(S)
Sum = Sum + Val(Mid(S, I, 1))
Next I
S = Trim(Str(Sum))
Loop
digitalRoot = CLng(S)
End Function
You could use a formula like:
=SUMPRODUCT(FILTERXML("<t><s>"&SUBSTITUTE(A1," ","</s><s>")&"</s></t>","//s"))
You might need an extra SUBSTITUTE for changing . to , if that's your decimal delimiter:
=SUMPRODUCT(FILTERXML("<t><s>"&SUBSTITUTE(SUBSTITUTE(A1,".",",")," ","</s><s>")&"</s></t>","//s"))
However, maybe a UDF as others proposed is also a possibility for you. Though, something tells me I might have misinterpreted your question...
I hope you are looking for something like following UDF.
Function SumToOneDigit(myNumber)
Dim temp: temp = 0
CalcLoop:
For i = 1 To Len(myNumber)
If IsNumeric(Mid(myNumber, i, 1)) Then temp = temp + Mid(myNumber, i, 1)
Next
If Len(temp) > 1 Then
myNumber = temp
temp = 0
GoTo CalcLoop
End If
SumToOneDigit = temp
End Function
UDF (User Defined Functions) are codes in VBA (visual basic for applications).
When you can not make calculations with Given Excel functions like ones in your question, you can UDFs in VBA module in Excel. See this link for UDF .. If you dont have developer tab see this link ,, Add a module in VBA in by right clicking on the workbook and paste the above code in that module. Remember, this code remains in this workbook only. So, if you want to use this UDF in some other file your will have to add module in that file and paste the code in there as well. If you are frequently using such an UDF, better to make add-in out of it like this link
In addition to using "Text to Columns" as a one-off conversion, this is relatively easy to do in VBA, by creating a user function that accepts the data as a string, splits it into an array separated by spaces, and then loops the elements to add them up.
Add the following VBA code to a new module:
Function fSumData(strData As String) As Double
On Error GoTo E_Handle
Dim aData() As String
Dim lngLoop1 As Long
aData = Split(strData, " ")
For lngLoop1 = LBound(aData) To UBound(aData)
fSumData = fSumData + CDbl(aData(lngLoop1))
Next lngLoop1
fExit:
On Error Resume Next
Exit Function
E_Handle:
MsgBox Err.Description & vbCrLf & vbCrLf & "fSumData", vbOKOnly + vbCritical, "Error: " & Err.Number
Resume fExit
End Function
Then enter this into a cell in the Excel worksheet:
=fSumData(A1)
Regards,
The UDF below will return the sum of all numbers in a cell passed to it as an argument.
Function SumCell(Cell As Range) As Double
Dim Fun As Double ' function return value
Dim Sp() As String ' helper array
Dim i As Integer ' index to helper array
Sp = Split(Cell.Cells(1).Value)
For i = 0 To UBound(Sp)
Fun = Fun + Val(Sp(i))
Next i
SumCell = Fun
End Function
Install the function in a standard code module, created with a name like Module1. Call it from the worksheet with syntax like =SumCell(A2) where A2 is the cell that contains the numbers to be summed up. Copy down as you would a built-in function.
I have an excel sheet set up to automatically calculate meetings per day by day of the week. I would like to write a formula to return all dates I have a meeting scheduled (comma separated preferably), but I am having some difficulty. Using Vlookup, I can only get it to return the first date.
For example, here is what my data looks like:
A B C
Initial Meetings Follow-up Meetings Date
1 1 7/29/2015
0 1 7/30/2015
1 1 7/31/2015
0 0 8/1/2015
0 0 8/2/2015
I would like to write a formula to return "7/29/2015, 7/31/2015" in one cell, and "7/29/2015, 7/30/2015, 7/31/2015" in another, but I seem to be stuck.
You can't do this with vLookup.
This can be done relatively easily in a VB script, but it would affect portability as many if not most users disable macros by default and in many cases users are prevented from using Macros because their company disables them and makes it policy that users should not use them.
If you are OK with Macros, you can put the following into a new module and then use =MultiVlookup(lookup_value,table_array, col_index_num) in the same way as you'd use vlookup and it should give you a comma separated list of multiple matches:
Public Function MultiVlookup(find_value, search_range, return_row)
Dim myval ' String to represent return value (comma-separated list)
Dim comma ' Bool to represent whether we need to prefix the next result with ", "
comma = False
'Debug.Print find_value.value, return_row
For Each rw In search_range.Rows ' Iterate through each row in the range
If rw.Cells(1, 1).value = find_value Then ' If we have found the lookup value...
If comma Then ' Add a comma if it's not the first value we're adding to the list
myval = myval + ", "
Else
comma = True
End If
myval = myval + Str(rw.Cells(1, return_row).value)
End If
Next
MultiVlookup = myval
End Function
This may not be the cleanest way of doing it, and it isn't a direct copy of vlookup (for instance it does not have a fourth "range lookup" argument as vlookup does), but it works for my test:
Finally my original suggestion (in case it helps others - it's not the exact solution to the question) was:
I've not tried it myself, but this link shows what I think you might be looking for.
Great code, but don't forget to add the following is you use Option Explicit:
Dim rw As Range
WHEELS
All the call signs will be in column A and when the macro is run should sort them. The sort is case insensitive usually in all caps. A call sign consists of 1-2 letters(prefix), 1-2 numbers(numbers), then 1-3 letters(suffix) I want to sort each sign by the number, suffix, then prefix in that order.
W9K, BB3C, W9GFO, AB8VN, G3G, A77Bc, KB8HTM, K9DOG, W8AER, K1ZZ, W4BFT, W0CQC, WA6FV, W6TRW, AA5B, W4IY, N4C, K5UZ, K4LRG
I will bite. Half the fun of coding is solving a problem for the simple pleasure of knowing you figured it out.
Here is a user defined function (Formula) that you can use to convert the call sign into the format for sorting. Note the numeric portion is zero padded so ones and tens do not sort together before twos and twenties.
Option Explicit
Public Function FormatCallSign(aCell As Range)
Dim Nbr As String
Dim i As Integer
Dim tmp As String
Dim vList As Variant
For i = 1 To Len(aCell.Value)
If InStr(1, "1234567890", UCase(Mid(aCell.Value, i, 1))) > 0 Then
Nbr = Nbr & Mid(aCell.Value, i, 1)
tmp = tmp & ","
tmp = Replace(tmp, ",,", ",")
Else
If InStr(1, "ABCDEFGHIJKLMNOPQRSTUVWXYZ", UCase(Mid(aCell.Value, i, 1))) > 0 Then
tmp = tmp & Mid(aCell.Value, i, 1)
End If
End If
Next i
vList = Split(tmp, ",")
FormatCallSign = vList(1) & Right("0" & Nbr, 2) & vList(0)
End Function
Put the formula in cell B2, for example by using the formulas command on the ribbon and selecting the function from the user defined section.
As asked earlier if the call sign had delimiters in it already, you could use a simple formula to rearrange the parts and exclude the delimiters.
=CONCATENATE(MID(A3,SEARCH("-",A3)+1,4),RIGHT("0"&MID(A3,SEARCH("/",A3)+1,SEARCH("-",A3)-SEARCH("/",A3)-1),2),LEFT(A3,SEARCH("/",A3)-1))
To build a formula like the above, start by constructing it in parts.
First write a Search function to find the "/", then copy it to find the "-"
Then write a mid function to get the characters to the right of the dash, left of the slash, then the numeric section. paste the formulas into a single formula for your masterpiece.
Since it makes better sense to keep the three elements in separate fields for simplified sorting, the above formula can be split into three separate formulas, one for each column.
=MID(A3,SEARCH("-",A3)+1,4)
=value(MID(A3,SEARCH("/",A3)+1,SEARCH("-",A3)-SEARCH("/",A3)-1),2))
=LEFT(A3,SEARCH("/",A3)-1)
This corrects sorting problems given the three elements are variable length.
The initial specification for callsign format is inaccurate, since they can begin with numbers or letters and a logical sort would be by ITU assigned prefix. A function would need a table lookup for country after it determined if the string after the forward slash was a valid country designation. This is actually a pretty complicated problem.
I have two unordered sets of data here:
blah blah:2020:50::7.1:45
movie blah:blahbah, The:1914:54:
I want to extract all the data to the left of the year (aka, 1915 and 1914).
What excel formula would I use for this?
I tried this formula
=IF(ISNUMBER(SEARCH(":",A1)),MID(A1,SEARCH(":",A1),300),A1)
these were the results below:
: blahblah, The:1914:54::7
:1915:50::7.1:45:
This is because there is a colon in the movie title.
The results I need consistently are:
:1914:54::7.9:17::
:1915:50::7.1:45::
Can someone help with this?
You can use Regular Expressions, make sure you include a reference for it in your VBA editor. The following UDF will do the job.
Function ExtractNumber(cell As Range) As String
ExtractNumber = ""
Dim rex As New RegExp
rex.Pattern = "(:\d{4}:\d{2}::\d\.\d:\d{2}::\d:\d:\d:\d:\d:\d:\d)"
rex.Global = True
Dim mtch As Object, sbmtch As Object
For Each mtch In rex.Execute(cell.Value)
ExtractNumber = ExtractNumber & mtch.SubMatches(0)
Next mtch
End Function
Without VBA:
In reality you don't want to find the : You want to find either :1 or :2 since the year will either start with 1 or 2This formula should do it:
=MID(A1,MIN(IFERROR(FIND(":1",A1,1),9999),IFERROR(FIND(":2",A1),9999)),9999)
Look for a four digit string, in a certain range, bounded by colons.
For example:
=MID(A1,MIN(FIND(":" &ROW(INDIRECT("1900:2100"))&":",A1 &":" &ROW(INDIRECT("1900:2100"))&":")),99)
entered as an array formula by holding down ctrl-shift while hitting Enter would ensure years in the range 1900 to 2100. Change those values as appropriate for your data. The 99 at the end represents the longest possible string. Again, that can be increased as required.
You can use the same approach to return just the left hand part, up to the colon preceding the year:
=LEFT(A1,-1+MIN(FIND(":" &ROW(INDIRECT("1900:2100"))&":",A1 &":" &ROW(INDIRECT("1900:2100"))&":")))
Here is a screen shot, showing the original data in B1:B2, with the results of the first part in B4:B5, and the formula for B4 showing in the formula bar.
The results for the 2nd part are in B7:B9
I'm a bit new to trying to program and originally was just trying to improve a spreadsheet but it's gone beyond using a basic function in excel. I have a table that I am having a function look at to find a building number in the first column and then look at start and finish dates in two other respective columns to find out if it should populate specific blocks on a calendar worksheet. The problem occurs because the same building number may appear multiple times with different dates and I need to to find an entry that matches the correct dates.
I was able to create a working though complicated formula to find the first instance and learned I can add a nested if of that formula again in the false statement with a slight change. I can continue doing that but it becomes very large and cumbersome. I'm trying to find a way to make a function for the formula with a variable in it that would look at how many times the it has already been used so it keeps searching down the table for an answer that fits the parameters.
This is currently my formula:
=IFERROR(IF(AND(DATE('IF SHEET (2)'!$F$7,MATCH('IF SHEET (2)'!$C$2,'IF SHEET (2)'!$C$2:'IF SHEET (2)'!$N$2,0),'IF SHEET (2)'!C$4)>=VLOOKUP("2D11"&1,A2:F6,4,0),DATE('IF SHEET (2)'!$F$7,MATCH('IF SHEET (2)'!$C$2,'IF SHEET (2)'!$C$2:'IF SHEET (2)'!$N$2,0),'IF SHEET (2)'!C$4)<=VLOOKUP("2D11"&1,A2:F6,4,0)),IF(VLOOKUP("2D11"&1,A2:F6,3,0)="2D11",VLOOKUP("2D11"&1,A2:F6,6,FALSE)),"NO ANSWER"),"ERROR")
Where you see 2D11&1 is where I need the variable for 1 so it would be "number of times it's been used in the function +1" then I could just loop it so it would keep checking till it ran out of 2D11's or found one that matched. I haven't posted before and I'm doing this through a lot of trial and error so if you need more info please post and say so and I'll try to provide it.
So rather than have someone try to make sense of the rediculous formula I posted I though I would try to make it simpler by just stating what I need to accomplish and trying to see how to turn that into a VBA function. So I'm kinda looking at a few steps:
Matches first instance of building name in column A with
building name for the row of the output cell.
Is date connected with the output cell >= start date of first entry(which is user entered in column D).
Is date connected with the output cell <= end date of first entry(which is user entered in column E).
Enters Unit name(located in column F) for first instance of the building if Parts 1, 2, and 3 are all True.
If parts 1, 2, or 3 are False then loops to look at next instance of the building name down column 1.
Hopefully this makes things clearer than the formula so I'm able to get help as I'm still pretty stuck due to low knowledge of VBA.
Here is a simple solution...
Building_name = ???
Date = ???
Last_Row = Range("A65536").End(xlUp).Row
For i = 1 To Last_Row
if cells(i,1).value = Building_Name Then
if date >= cells(i,4).value Then
if date <= cells(i,5).value Then
first instance = cells(i,6).value
end if
end if
end if
next
you should add a test at the end to avoid the case where there is no first instance in the table
If I understand correctly, you have a Table T1 made of 3 columns: T1.building, T1.start date, T1.end date.
Then you have 3 parameters: P1=building, P2=start date, P3=end date.
You need to find the first entry in table T1 that "fits" within the input parameters dates, that is:
P1=T1.building
P2<=T1.start date
P3>=T1.end date
If so, you can define a custom function like this
Public Function MyLookup(Key As Variant, DateMin As Variant, DateMax As Variant, LookUpTable As Range, ResultColumn As Integer) As Range
Dim iIndx As Integer
Dim KeyValue As Variant
Dim Found As Boolean
On Error GoTo ErrHandler
Found = False
iIndx = 1
Do While (Not Found) And (iIndx <= LookUpTable.Rows.Count)
KeyValue = LookUpTable.Cells(iIndx, 1)
If (KeyValue = Key) And _
(DateMin <= LookUpTable.Cells(iIndx, 2)) And _
(DateMax >= LookUpTable.Cells(iIndx, 3)) Then
Set MyLookup = LookUpTable.Cells(iIndx, ResultColumn)
Found = True
End If
iIndx = iIndx + 1
Loop
Exit Function
ErrHandler:
MsgBox "Error in MyLookup: " & Err.Description
End Function
That may not be the most performant piece of code in the world, but I think it's explanatory.
