Clusters to Spreadsheet (Excel)

Hello all,
I would like to save the array (clusters) I have and save it to a file. As you can see from the file, the clusters holds two string information ( date and time) and a numeric section. I would like to export this data to excel.
Conditions:
1) I want it to save to a specfic folder every single time I run the program WITHOUT asking me where to save the file
2) Saving a new file in the same folder should contain a template and go number itself according to that...(For example... Sample.csv...Sample(1).csv...Sample(2).csv and so on.
Ive tried to us etyhe write to spreadsheet functions and they don't meet my conditions.
Any help is great!
Thank you!

Replace different values in different cells

Hi,
I am new to LabVIEW and work with an instrument that gets it's settings from an Excel file. I need to change those settings in Excel with LabVIEW. The Excel file is formated in .xls (97-2003 version). The PC has Microsoft Office 2013 installed.
I am using LabVIEW 2014 (64-bit).
Task:
I want to change the values in 3 different cells in an Excel spreadsheet and save the workbook (not SaveAs).
The main vi is saved in the library in the zip file, it is called 'change 3 values in excel.vi'.
The excel file is attached separately.
I don't think it matters where those cells are in the Excel worksheet, the Excel memory seems to keep the cell selection of all cells in mind but replaces the value with the last one mentioned in the last sub vi.
Problem:
1) All cells change to the same value that I define in the third sub vi.
2) Excel asks me for SaveAs and doesn't just save over the existing file.
3) The Excel application doesn't close but I can't seem to figure out why.
Please advice. Help on any of those issues is highly appreciated.
Thank you!

Here is how I would do this. I would use the Report Generation Toolkit (which is included in LabVIEW 2014). This Example is a simplified version of your task -- you are given the name of an existing Excel Workbook to modify, the index of the Worksheet to use, the Excel Cell address (in Excel format, i.e. A1, for purposes of illustration), and the Cell Value that you want to insert there.
The first function is New Report, which is a slight misnomer, as we are using it as "Replace Report" by wiring in the name of the existing Report, and specifying that we mean an Excel Report (it will open Excel -- if you don't want the Workbook to be visible, open it Minimized). We next call Excel Get Worksheet (which isn't necessary if we are using the first Worksheet ...). We use Excel Easy Table to put the Cell Value into the chosedn Excel Cell. To do this, we first use Excel Get Excel Location to convert, say, B3, to row/column indices (B3 = 1, 2) and bundle this into a Cluster. We also need to convert the Cell Value into a 2D Table which we do by passing it through two Build Array functions. Next we Save Report to File using the original Excel Workbook path, and finally we Dispose Report to turn off Excel.
If you had multiple cells you wanted to update, I would bundle Excel Cell and Cell Value into a cluster, build an array of clusters, then put the Excel Easy Table function into a For loop and do the updates one at a time.
This should work extremely quickly -- the entire process should take a fraction of a second.

Getting clusters from LabVIEW ActiveX Server with Excel/VBA

Hello,
my colleague and I are trying to control a LV from Excel (VBA) by ActiveX.
I.E.:
We do something like :
Set LV = createObject("LabVIEW.Application")
Set VI = LV.GetVIReference("Path_to_VI")
ParamNames(0) = "Input1"
ParamNames(1) = "Input2"
ParamNames(2) = "Output"
ParamValues(0) = 1
ParamValues(1) = 3.1415
Call VI.Call(ParamNames,ParamValues)
msgbox("output =" & ParamVals(2))
This works perfectly for simple data types (int, double, float, string, etc )
Now we need to transfer more complex structures, which are originaly LV-clusters.
But we did not find any clue on how do that (especially receive clusters) in the help or on the internet.
Is there any chance to succeed ???
TIA,
Thomas

Actually, working with clusters is really really easy. Through the magic of - well something - a cluster in LV comes out in the VBA environment as an array of variants. There was an activex example that shipped with V7.1 that showed this very thing. I couldn't find them in V8 so here is the 7.1 stuff.
Check out the macros in the Excel spreadsheet... This show running the VI in the development environment, but if this looks interesting I can fill you in on how to make it work in an executable.

Sequence Clustering in Excel DM Add-In 2013, Cannot Set Sequence Key

Hi Everyone,
I was attempting to run a Sequence Clustering DM in Excel and I tried to get around the need for a nested table by flattening my normalized Sales Order and Sales Order Line Item into a single table through a query.
However, when I go to create the Mining Structure in Excel, there is no option for setting the Key Sequence. If I go try to add a Mining Model to a mining Structure, Sequence Clustering is an option but I cannot proceed unless I set the Key Sequence when
I am building the Mining Structure.
Does MS Excel DM support Sequence Clustering analysis? Or is there a workaround within Excel?
Thanks,
Billy

You cannot create Sequence Clustering models in DM Add-ins.

How do I read from a text file that is longer than 65536 lines and write the data to an Excel spreadsheet and have the data write to a new column once the 65536 cells are filled in a column?

I have data that is in basic generic text file format that needs to be converted into Excel spreadsheet format. The data is much longer than 65536 lines, and in my code I haven't been able to figure out how to carry over the data into the next column. Currently the conversion is done manually and generates an Excel file that has a total of 30-40 full columns of data. Any suggestions would be greatly appreciated.
Thanks,
Darrick

No need to use nested For loops. No need for any loop anyway. You just have to use a reshape array function. The picture below shows how to proceed.
However, there may be an issue if your element number is not a multiple of the number of columns : zero value elements will be added at the end of the last column in the generated 2D array. Now the issue depends on the way you intend store the data in the Excel spreadsheet : you could convert the data as strings, replace the last zero values with empty strings, and write the whole 2D array to a file (with the .xls extension ) using the write to spreadsheet function. Only one (minimal) problem : define the number of decimal digits to be used;
or you could write the numeric array directly to a true Excel spreadsheet, using either the NI report generation tools or ActiveX commands, then replace the last elements with empty strings.
We need more input from you to decide how to solve these last questions.

How can i print an excel spreadsheet file by clicking a button on the front panel

i have designed a vi that logs data into an excel spreadsheet. i want to take print out of the file when the user clicks a button on the front panel. what to do if there is very large amount of data.

Preet,
Printing the Excel sheet is just an ActiveX method call to print the worksheet. To add data to the worksheet, you already have the reference, just call a print method. As for handling large amounts of data, that is a vague question. The data will print how ever you placed it on the worksheet. If what you mean is that you don't want to print out 25 pages every time, the print method has options to only print specific pages or ranges. You may want to play around with a sample spreadsheet to learn the printing options. For help on the ActiveX functions, make sure you have the Visual Basic help installed for Excel.

Changing default color scheme when exporting ALV report to Excel spreadshee

Hi all,
We have a bunch of FI reports created using OOPS in abap. Each of the reports has the functionality to be exported to an excel spreadsheet. When exporting to Excel, the headers are a very dark brown color, making them difficult to read and it has been requested that they are shaded a lighter color. I have not defined any sort of color scheme within the report itself, and I was wondering if there was a way to change the color scheme when exporting the report to excel. Let me know if there is anything that can be done, thanks!

Manipulating the cell size in an Excel spreadsheet

Problem 1 of 2 (2 is in the same project but a different function so will place in separate post)
Using LV 2013 on Windows 7 with Excel 2010
I have a routine where I insert assorted data into an Excel spreadsheet based on a pre-formatted Excel template. Problem is, when one group of data is placed in the range of cells (ends up being a column because of the way the data array is formatted) that particular column width is reduced.
Because once of the cells automatically formats as the Excel Date / Time format (as desired) the narrower width of the cell makes the value unreadable. (Just like when a real numerical value is longer than the cell is wide, all you see is hash marks)
I verified my column width in the template is where it should be, it definitely is reduced when the data is entered. I also tried using the “Excel Set Cell Dimension.vi” to change the cell width back to what I need but it does not work. Not sure why. When I tried placing the function at the beginning of the routine, I think it created an error and the rest of the report/excel functions failed to work. I didn’t monitor the error wire to confirm this.
My next approach will be to write a macro in the template file and call this at the end to fix the cell width but this seems like the long way around.
Any thoughts on the best way to fix this? Or why the “Excel Set Cell Dimension” function does not work?
Thanks…..

Am using report toolkit. Have not looked inside the vi(s) but will do so to see if I can pull out some functions that I can manipuate to work my issue.
Will report back when I figure something out. Probably next monday, off work tomorrow, Whoo Hoo

Import a column from an excel spreadsheet, then enable/disable boolean controls in a cluster based on imported values

Greetings all. I have an application I've been developing and refining for some time. Part of it entails an interactive periodic table of elements where the user can select multiple elements to include in a multi-element chemical standard. The part I'm having difficulty with now is disabling multiple elements within the periodic table. Specifically, what the scientist wants is to be able to reference an excel inventory that they keep of available on-hand single-element standards. I need to be able to read in column A of that spreadsheet, build a distinct array of those elements listed (some are listed more than once) and then disable the boolean controls in my periodic table for those elements not in the array (or enable those elements which are in the array, whichever makes themost sense). This way, the analyst cannot select elements in the periodic table for which thay have no on-hand inventory. I see how to enable or disable all controls in a boolean cluster, and I see how to enable/disable a single control, but I'm looking for an elegant way to import the excel column, build an array of thsoe values and then enable only those values. Any help is always appreciated. Thanks again.

Problem export pdf table to excel spreadsheed

Hi, my name is Marco.
Last month a customer has bought a copy of Adobe Acrobat Professional 9 in my computer shop for edit some pdfs files.
After some days he told me that he need to export a table to excel's spreadsheet but the function "open table in excel spreadsheet" work ONLY for the page where i right-click. How can i copy all the document in excel (without lose the format)?
Sorry for the bad english, if you don't understand i try to rewrite it better or in Italian!
Thank you!

A lot depends on the structure of the PDF. I it has tags included that provide the format information, then the conversion may be easy. If the tags are not included, then retaining the format is almost impossible. This may even be a problem with recognizing columns. In that case, selecting columns with the ctrl key held during the selection. More information is available under "Copying Text" in the help menu (complete help). The help also talks about the ability to retain format as I have suggested.
To select items on multiple pages, you have to use continuous view.
It might be easier to the Save As to DOC and go from there. The backward conversion is not the forte or intent of Acrobat. In reality, one should never delete the original XLS (or other) file with the intent of going back in the future. Sounds like it is too late for your customer.

I am using Activex controls from Labview to log the data into Excel spreadsheet. My applica

tion is running fine without giving any error messages. But even after the vi stops, excel process does not shutdown. "Excel.exe" process keeps running until I end it from Windows NT Task Manager. Is there any way to end the excel.exe process from Labview?

tion is running fine without giving any error messages. But even after the vi stops, excel process does not shutdown. "Excel.exe" process keeps running until I end it from Windows NT Task Manager. Is there any way to end the excel.exe process from Labview?I use Excel Active X control frequently to save and then analysis test data. In order to properly destroy the "Excel.exe" process it is important to close all the automation refnums opened when using the Excel active x controls. After completing your desired Excel task wire all the refnums in reverse order they were created into the Automation Close function in Functions->Communication->Active X pallette. This includes all Application, Workbook, Worksheet, or Range refnum. Missing even one of these refnums will mean that Excel.exe will still persist in the task manager and cause problems when excel is opened from outside LabVIEW. I hope this helps.

I can not open Excel (97, 2000, or 2003) spreadsheet in Win98 OS PC using LabVIEW 7.0 Runtime Engine

Hi,
I have a problem opening an Excel spreadsheet by a LabVIEW application that is using Runtime Engine 7.0 in a Windows 98 OS environment .
I tried LabVIEW 7.1, it will not install on Win98. Meanwhile, I installed Excel 97 and 2000 (Excel 2003 does not install on Win98) and tried to open the spreadsheet, no luck with any combination.
Same code can open the spreadsheet in a WinXP OS, RTE 7.0, Excel 2000/2003 environment.
What can I do? Any advise?
Regards,
LVLV

Hi,
I did some experiment, I found out that Run-Time Engine 7.0 running executable generated at LabVIEW 7.0 environment (code written in LabVIEW 7.1 but save as 7.0) cannot open Excel 2000 files. If I replace Excel 2000 with Excel 2003 application on my pc, the executable code will open the Excel file (Run-Time Engine 7.0 works with Excel 2003).
Is the Excel 2003 and higher versions will only work with Run-Time Engine 7.0 and higher code?
How can I make executables using Run-Time Engine 7.0 work with Excel 2000 (Windows 98 operating system)??? (I cannot change Excel and Run-Time Engine and OS versions due to limitations, how can I work with what I have?).
Thanks for your help.

Excel tdms add in not showing data in spreadsheet

I've succesfully installed the Excel TDM Add In on several computers.
The latest computer I tried to set up lets you select a TDMS file to import but the channel data does not appear. I've uninstalled and reinstalled several times with no luck. There are two example files attached. One from a successful import and another that is missing the data. Both files used the same source TDMS file which is also attached.
It is running Windows 7 64-bit with MS Office 2010 - no different from the computers that the add in works on.
Any idea what could be wrong?

What you forgot to mention is what process did you do to import the one that worked, and the one that didn't work?
Was it the same process?
All I did was double click the TDMS file. By default it will open it with the TDMS Importer and open it in Excel. For me the import was fine and I had all the data that your Successful version did.
If you are interested in automating this feel free to try out my importer utility.

It relies on the TDMS Excel add-in but it allows for other formatting, and freezing rows/columns in the data as well as providing an alternative summary page.
