I am trying to import data to a table. Basically its a MCQs. All my questions are having superscripts and subscripts, for example X2 , and log52....
I have more than 2000 records, i have to import it. But after importing it comes in plain format, not taking powers. My DB is MYSQL (UTF-8)
Here is the example data
If log5 2, log5 (2x - 5) and log 5(2x - 7/2) are in AP , then x is equal to
after impoting it looks like above, but actually it should be
If log5 2, log5 (2x - 5) and log 5(2x - 7/2) are in AP , then x is equal to
Somebody plz suggest me how to do it
Here's a quick fix for the Subscripts:
Sub log_Script()
Dim cel As Range, rng As Range
Dim i&, k&
Dim myText$, findText$, curStr$
Set cel = Range("A1")
'myText = cel.Value
For i = 1 To Len(cel.Value)
k = k + 1
curStr = Mid(cel.Value, i, 1)
If curStr <> " " Then
findText = findText + curStr
ElseIf curStr = " " Then
findText = ""
End If
Debug.Print findText
If findText = "log" Then
If Mid(cel.Value, i + 1, 1) = " " Then
With cel.Characters(Start:=k + 2, Length:=1).Font
.Subscript = True
End With
Else
With cel.Characters(Start:=k + 1, Length:=1).Font
.Subscript = True
End With
End If
End If
Next i
End Sub
This will go through a range (set currently to be A1:A10), and for each cell, it'll look for log then take the next number and make it subscript. (Note: This is assuming all logs will have base < 10, let me know if that's not necessarily the case).
I could probably make this better, if you can post a few rows or cells from your CSV so I can see what the formatting is exacly like. (Or screenshot a part of your data, that 'd work too).

I am given N lists of M items that will be physically realized (someone actually has to put items (names abbreviated here,) in physical bins.) Then the bins are emptied, if necessary, and re-used, working left-to-right. There is a real cost to putting a different item in a bin than what was in it before. I rearrange the lists to minimize changes, manually. Software can do it faster, and more reliably in an optimum way. The whole thing happens in Excel (then paper, then in a factory.) I wrote some VBA, a brute-force affair, that did really well with some examples. But not all. If I knew the family of optimization that this is, I could code it, even if I just pass something to a DLL. But multiple searches online have not succeeded. I tried several phrasings. It's not a traveling S.., knapsack, etc. It seems similar to the Sequence Alignment problem from Bioinformatics. Someone recognize it? Let's hear it, Operations Research people.
As it turns out, the naive solution just needed tweaking. Look at a cell. Try to find the same letter in the column to it's right. If you find one, swap it with whatever it to the right of that cell now. Work your way down. The ColumnsPer parameter accounts for the real-world use, where each column has an associated list of numbers and the grid columns alternate labels, numbers, labels, ...

Let's say I have four data values and one of them exists sometimes.
My For loop crashes because the path doesn't exist.
I would like to pass a "" in the cell instead of crashing.
myJSON.data[i].bank[0].money <- this part is my problem, because the bank[0].money sometimes doesn't exist.
I would like to keep the cell empty.
I tried an If but I didn't get it formatted properly, same goes for error handling.

You can handle null by using optional chaining with default nullish coalescing (#3 in example).
Something like this should work
Change myJSON.data[i]?.bank[0]?.money
To myJSON.data[i]?.bank[0]?.money ?? 'Unknown'
You can do the same with your other variables (myJSON.data[i].location and myJSON.data[i].planneddate) if they have the potential to be undefined or null as well
EDIT - Use Optional IF when optional chaining is not available
If that feature is not available in HTMLDocument's javascript maybe you can use basic conditional if?
This should work for undefined object, because undefined is == null
(myJSON.data[i].bank[0].money != null ? myJSON.data[i].bank[0].money : '-')

Attached is a "Cut down" version of the code. I am writing to an Excel spreadsheet to apply Indirect formula. [CostType] and [SoftwareCosts] in the example are constants at the moment.
I want the user to be able to add fields without then having to amend the code. The new field name will be derived from the table. Is it possible to use a field name (not known until the table is modified) between the square brackets?
Yes:
FieldName = "SomeField"
WKS.Cells(199 + R, 1) = RSNonResourceCosts.Fields(FieldName).Value
This problem is in an Excel .xls file.
Simplest Use Case:
Column A has one row.
Column B has 5 rows.
The 5 rows in Column B need to be merged into one row, delimited by newlines.
I have a huge .xls document where there are a ton of IDs in column A.
There are on average anywhere from 3 to 10 rows that belong to each column A row.
How to know which Column B rows belong to which Column A?
By the positioning of the cells.
One Column A row may have 5 Column B rows to the right of it.
I don't have any VBA experience.
I have looked around for macros and functions but haven't had any luck finding anything that matches this problem.
Edit:
I am now trying to figure out how to get the script to ignore rows that have a one-to-one mapping between column A and column B.
Edit again - 06-20-2012:
Now that I can attach images, here is a screenshot of an image for what I'm trying to get.
The rows for Brian and Mark should be ignored, while Scott and Tim get their values copied over.
Edit:
Unmerging column A, using the code that Andy supplied, and then using this VB script afterwards does the trick:
Sub mergeA()
For i = 2 To Cells(65535, 1).End(xlUp).Row
If IsEmpty(Cells(i, 1)) Then Range(Cells(i - 1, 1), Cells(i, 1)).Merge
Next
End Sub
That VB script puts the cells in column A back together
I didn't make the script, it came from this web page:

I am trying to compare two recordsets. the first rs1 has random records. The second rs2 has the standard values for those records. Initially I am looking to take each of the records and see if they match with the standard set of values in the second recordset. There are four fields in each record set to be compared and all four must match.
I just need some help in the loop. I am trying to write the non matching records to an excel file.
Here is what I have so far
While Not rs1.EOF
With rs1
.MoveFirst
With rs2
.MoveFirst
While Not rs2.EOF
counter = counter + 1
a = 0
If rs1!Kk = rs2!Kk Then a = a + 1
If rs1!CC = rs2!CC Then a = a + 1
If rs1!HN = rs2!HN Then a = a + 1
If rs3!TN = rs2!TN Then a = a + 1
If a > 3 Then GoTo correct
.MoveNext
If rs2.EOF Then
If rs!Table_Name <> "table1" Then
i = i + 1
j = 1
counter = counter + 1
objSht.Cells(i, j).Value = "casenum" & rs1.Fields(1)
j = j + 1
stat_counter = stat_counter + 1
End If
If i = 65500 Then
Set wbexcel = objexcel.ActiveWorkbook
''//Set objSht = wbexcel.Worksheets("Sheet2")
Set objSht = wbexcel.Worksheets.Add
i = 2
End If
End If
correct:
rs1.MoveNext
Wend
End With
End With
Also any ideas on how i can segregate based on 2 of fields matching with standard and 3 of the fields matching with the standard values
Are the recordsets already sorted? I'm guessing that's the case since you move to the next rs2 on a non match. Personally i'd specify a sort to make 100% sure.
Also I'd test this pretty thoroughly with a small test dataset with a few edge cases to make sure you get what you expect.
With the above in mind your code looks like it'd work but i have a few small recommendations to make it easier to read.
First i'd recommend ditching the nested With rs1 and With rs2. Just refer to each recordset explicitly so you can clearly see what is happening to each rs. eg:
If a > 3 Then GoTo correct
.MoveNext
becomes
If a > 3 Then GoTo correct
rs2.MoveNext
Next your if statements with a = a + 1 could do with some tidying. eg:
If rs1!Kk = rs2!Kk and rs1!CC = rs2!CC and rs1!HN = rs2!HN and rs3!TN = rs2!TN then
''// Do Nothing or maybe increase a count or whatever :)
else
WriteToExcel(objSht , rs1.fields)
end if
You'll need to write a function called WriteToExcel() but this will make the next step easier. I think you want to write to different sheets depending on the matches?
If rs1!Kk = rs2!Kk and rs1!CC = rs2!CC and rs1!HN = rs2!HN and rs3!TN = rs2!TN then
''// Do Nothing
else if rs1!Kk = rs2!Kk and rs1!CC = rs2!CC and rs1!HN = rs2!HN then
WriteToExcel(objSht2 , rs1.fields)
else
WriteToExcel(objSht , rs1.fields)
end if
You may also want to look at switches in the case where you need any two matches, rather than specific matches as above... oh and variable j seems a bit superfluous.
My gut says you are doing something sub-optimally; however, in the if statement If rs2.EOF Then, why not add a comparison to a and then redirect to a different Excel file for 0, 1, 2 and 3
Bruit Force and Ignorance, but definitely segregated.
