Can I open a excel file from labview

I have a program who write temperature in a excel file and i want to open this file from labview .

This depends slightly on the amount of data you have stored within Excel.
You can use the "Labview Functions>>FileIO>>Read from Spreadsheet file.vi" which effectively reads all lines from a text file and converts it into a numeric array.
Alternatively, if your data structure in Excel is more complex than this, you can use ActiveX calls to Excel to retrieve it.
Use an "ActiveX>>Automation Refnum" control and select the Excel server class. This will then enable you to access properties and methods of Excel to retrieve data from specific cells and pages.
The attached example should help.

  • How to open an excel file from labview?

    I tried to use "open file" vi from File I/O -- Advanced file functions to open an excel file in LabVIEW. Why the excel file wouldn't open after I run the program?

    In addition to ActiveX, you can also manipulate Excel data files using the Windows ADO interface - a technique that is more robust, faster and IMHO easier. Do a search on the forum as there have been several threads within the last week or so discussing this very thing.

  • Office 2013 can't open word, excel files from the network after upgrade to 8.1

    Hello,
    Recently, I upgraded all PCs from WIN 8 to Win 8.1. After the upgrade I noticed that I can't open any word documents and excel files. Before the upgraded I have no problem opened any files. All PCs have over 500GB free space on hard drive. Other PCs that
    run Win 7 have no problem open them only the one with Win 8.1. This is what I got:
    I right click--> property and there is no unblocked. All files resided on the network server.
    Please help.

    Hi Jimmy,
    Did you get any error message when you try to open an Excel file/Word document?
    If so, you can post the error message and  event log here.Also ,if you had antivirus software installed, try to disable them to test this issue.
    In addition, what happens if you add the network server location as a trusted location?

  • Can't open web pdf files from my Reader DC because my IMac wants a completed license agreement to use Reader and I never saw that page during installation.

    Can't open web pdf files from my newly installed Reader DC because my IMac wants a completed license to use agreement to Reader, and I never saw that page during installation.  How do I get past this?

    You need to accept the EULA on first launch of the Reader DC application.
    Go to the Applications folder and launch Adobe Acrobat Reader DC. 
    This will bring up the EULA.
    Select the "Agree" button if you agree with the terms
    Assuming you selected the "Agree" button, Reader DC should open.
    You should now be able to open PDF files in your web browser.

  • I can't open the RAW files from my new Nikon D4s camera in photoshop? How do I download the latest software for RAW files?

    I can't open the RAW files from my new Nikon D4s camera in photoshop? How do I download the latest software for RAW files? Cheers!

    What version of Photoshop are you running?  You will need at CS5, CS6, CC or CC2014.  Each version needs a different ACR-plug-in to open files from that camera.
    If you are on CS4 or earlier, you'll need to upgrade—or, in the alternative; look for, download, instal, launch and run the free, stand-alone DNG Converter 8.6 on each file of raw NEF files to convert them to raw DNGs first so you can open them in your version of Photoshop and ACR plug-in higher than 2.4.

  • I have Lightroom 3.6 and Camera Raw 6.6 but I can't open my CR2 files from my Canon eos 6D

    Hi,
    I have Lightroom 3.6 and Camera Raw 6.6 but I can't open my CR2 files from my Canon eos 6D
    Lightroom doesn't show a thumbnail image and when trying to import it says the camera format isn't supported. But normaly Camera raw 6.6 should cover the Canon eos 6D
    All help is welcome,
    Thanks

    No, the older versions are not free.  If you upgrade you will have to get Lr5 unless you can still find Lr4 for sale somewhere as it has been discontinued by Adobe.  You can also use the FREE DNG converter to convert the 6d files for use in Lr3.6.

  • I have just bought a Panasonic Lumix compact camera. Aperture and Preview can't open the RAW files from this camera. Panasonic recommend downloading 'SYLKPIX Developer Studio SE' to save RAW file formats.How can Aperture and Preview read the files?

    I have just bought a Panasonic Lumix compact camera. Aperture and Preview can't open the RAW files from this camera. Panasonic recommend downloading 'SYLKPIX Developer Studio SE' to save RAW file formats.How can Aperture and Preview read the files?

    Either use 'SYLKPIX Developer Studio SE' to develope the RAW files and to save them in another lossless format like TIFF, or try if Adobe's free DNG Coverter can convert your Lumix RAW files to dng. Then import the dngs. This way, your files will still be RAW files.  This works (most times) for my Lumix FZ28.

  • Can't open any excel files after installing Snow Leopard

    I can't open any excel files after installing Snow Leopard. Is anyone else having this problem?
    I have a standard iWork '08 install. Has anyone experienced? And better yet, know of a fix?

    Welcome to Apple Discussions
    Most users who have had a problem opening Office files with the iWork apps after upgrading to Snow Leopard have the problem fixed by updating to the latest versions. For iWork '08 that is Pages 3.0.3 & Numbers 1.0.3. For iWork '09 it's Pages 4.0.2 & Numbers 2.0.2. I don't use Keynote, but it should also be updated. If you're not running the latest versions & Software Update says your software is up to date, make sure the applications are where the installer initially put them. The updaters are very picky. If the location is not where the updater is programmed to look or if the folder doesn't have the name the updater looks for, it will not work. The applications cannot be renamed or moved. They must be in the iWork '08 or iWork '09 folder in Applications. That iWork folder must be named iWork '08 or iWork '09. If it doesn't have the '08 or '09 Software Update won't find them & the updaters won't work.

  • Why does TDM Importer start up when I open an Excel file in LabVIEW, and how can I stop it?

    I have a new application using LabVIEW 2012 SP1.  I open an Excel file using the Report Generation toolkit and when I do so, a small TDM Importer window pops up on top of the Excel file.  
    How can I prevent this?

    Hi Steve,
    The TDM Importer pops up because the report generated in LabVIEW is in the TDMS file format.  TDMS is a binary file that requires an importer to make sense of the binary data and translate it into an Excel spreadsheet.  As per this white paper, the appearance of the floating toolbar is expected behavior:  http://www.ni.com/white-paper/5874/en/
    To the best of my knowledge, you cannot get rid of the floating toolbar unless you uninstall the add-in, in which case you probably would not be able to open your LabVIEW-generated reports.  However, as of Excel 2007, the toolbar is embedded in the "Add-Ins" tab instead of floating on your spreadsheet.  You can see how the toolbar looks as of Excel 2007 in step 6 of this white paper:  http://www.ni.com/white-paper/5885/en/
    If there is a way to embed the toolbar in Excel 2003, it would be the exact same way you would embed any other floating customer toolbar in Excel.  In other words, I don't think this has anything to do with the fact that it's NI's add-in.  This is just the way Excel 2003 and earlier treats add-in toolbars.  Someone on these forums may well know a way to embed it (perhaps a macro?), but you may have better luck contacting Microsoft.  I'm not sure whether it's even possible for a user to embed the toolbar.

  • I want to open an excel file from a folder in the Microsoft live office on Hotmail. Their instruction is to go to tools in Firefox, go to plug-ins and then install Microsofts Office 2010. Can't find plug-h. Help?

    I have uploaded an excel file from my desk top to the Windows Live (HOTMAIL?) office suite. When I try to open the file I get an error that says my system is not supported. My system passes all of the listed criteria except for one. That is a plug in from Firefox. The instructions say to go to the Firefox menu, click on tools then plug-ins. Of course when I go to tools plug-ins is not immediately available, but when I do go to plug-ins, I am to click on Microsoft Office 2010. This plug in is supposed to allow earlier versions of office documents to be viewed as well as Office 2010. The plug-in is not available. When I search the Firefox website I am not able to find such a plug-in.
    I am using Microsoft XP, Office 2007 and the version of Firefox prior to V4. V4 does not support all of my e-mail clients so am not able to use V4.

    I am using Microsoft XP, Office 2007 and the version of Firefox V4 but I have this same problem.

  • Downloaded latest version of Firefox and now can't open any Excel files

    The problem started right after I downloaded the latest version of Firefox (4?). When I try to open my Excel files I get a Windows error message and then it says that Excel can not find the file.

    A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
    Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process.
