Hi,
I did some calculations in DIAdem and are stored in separate channels(Arithmetic Mean, Standard Deviation, etc...).I want these values to be in Excel in a particular format. I tried to use Excel plugin but it is not working and I am not able to write data in the channels created by Excel plugin.
Please convey.
Solved! Go to Solution.

Hi himanshu25,
If you're in an interactive session, you can copy columns from a DIAdem VIEW table with <Ctrl-C> and paste them into an open Excel worksheet with <Ctrl-V>.
You can save the selected channels to a temporary *.TDM or *.TDMS data file, then use the Excel TDM Addin to load the *.TDM/S data file into Excel.
You can save the selected channels to a temporary *.csv or *.txt data file, then use the Excel ASCII file importing functions to load that data into Excel.
You can create a VBScript that communicates with Excel using ActiveX and sends the data channels to an Excel worksheet programmatically.

Hello Brad,
Thanks!!!!
I have a *.TDMS file and after performing some calculations I have some new channels. I want to export the calculated data to an Excel file. The last option looks good but i don't know how to do that and I can't provide the data.
However, I have attached a similar excel file which I need as an end product.
It will be a great help for me if I can get a VB Script on how to write to an excel file.
Have A Great Day

Here is a script I used to use when I needed to verify some test type before loading it into DIAdem.
The reading/ writing into excel function is at the top, and I use it at the bottom of the script. It used to be only for reading a single cell value (that is why it's name getSingleCellVal) but I added writing for this purpose.
'-- Comment: Function to return a value off a single cell in and excel file (or csv) and replace it with another value '------------------------------------------------------------------------------- Option Explicit 'Forces the explicit declaration of all the variables in a script. DIM SUB_NAME, FSO Set FSO = CreateObject("Scripting.FileSystemObject") ' READ A VALUE OF AN EXCEL / CSV SHEET ' ARG 1: The path of the file to be read ' ARG 2: the row containing the value of interest ' ARG 3: The column containing the value of interest ' ARG 4: A1 range string ' ARG 5: The new value to place in the A1 cell ' RETURN: Returns the old value of the cell ' NOTES: n/a Function getSingleCellVal(filePath, row, col, A1range, newVal) SUB_NAME = "getSingleCellVal" & ": " Call LogFileWrite(SUB_NAME & "Started exeution") ' START If TypeName(filePath) = "String" And (TypeName(row) = "Integer" Or TypeName(row) = "Long") And (TypeName(col) = "Integer" Or TypeName(col) = "Long") Then If FSO.FileExists(filePath) Then ' If the file in question exists If LCase(FSO.GetExtensionName(filePath)) = "csv" Or LCase(FSO.GetExtensionName(filePath)) = "xlsx" Then ' Check if the file is excell or csv If row > 0 And col > 0 Then Dim Excel ' Open the excell sheet Set Excel = CreateObject("Excel.Application") Excel.Visible = TRUE Call Excel.Workbooks.Open(filePath) getSingleCellVal = CStr(Excel.ActiveSheet.Cells(row, col).Value) ' READ THE OLD VALUE Excel.ActiveSheet.Range("A1").Value = newVal ' WRITE VALUE Call Excel.ActiveSheet.Parent.Save() ' SAVE ' Close Excel Excel.DisplayAlerts = False Excel.Quit Set Excel = Nothing Else Call LogFileWrite(SUB_NAME & "row and column values must be greater than zero... Aborting") End If Else Call LogFileWrite(SUB_NAME & "must be xlsx or csv file extensions... Aborting") End If Else Call LogFileWrite(SUB_NAME & "file does not exist... Aborting") End If Else Call LogFileWrite(SUB_NAME & "argument types must be 1-String, 2-Integer, 3-Integer... Aborting") End If ' END Call LogFileWrite(SUB_NAME & "Ended exeution") End Function ' USING THE FUNCTION Dim oldVal, newVal newVal = "I wrote that" oldVal = getSingleCellVal("C:\Users\111660\Desktop\new.xlsx", 1, 1, "A1", newVal) Call LogFileWrite(oldVal)
Let me know if I can clarify
There is a ton of documentation on Excel and VBS here: https://docs.microsoft.com/en-us/office/vba/api/overview/excel With all the object methods and properties under the object model tab. I prefer TDMS usually but a lot of people don't have DIAdem or can't use it so I use this stuff sometimes.

Hi Himanshu,
Here's an example script that exports a given group from the Data Portal in the format you requested.
Set RawGroup = Data.Root.ChannelGroups(2) Set RawChannels = RawGroup.Channels Set myExcelApp = CreateObject("Excel.Application") myExcelApp.Visible = TRUE myExcelApp.Workbooks.Add() Set myWorksheet = myExcelApp.Activesheet myWorksheet.Cells(1,1) = "Excel-Example" FOR j = 1 TO RawChannels.Count myWorksheet.Cells(2,j) = RawChannels(j).Name myWorksheet.Cells(3,j) = ChnDim(RawChannels(j)) NExt ' j Set myRange = myWorksheet.Range("a4") Set myRange = myRange.Resize(RawChannels(1).Size, RawChannels.Count) myRange.Value = ChnToVariant(RawChannels, "TransposedMatrix") Set myExcelApp = Nothing

Hi Brad,
The script is used to write only one channel group. What if I want to write the next group?

And the channel has only one value.

Hi Brad,
I don't very understand last few lines from the code (from set myRange ...to the end)
Can you shed some light?
Instead of change excel name after running script, can I directly assign a file name to excel in script step?
