Labview Timestamp to Excel Time Formatted Cell

Hello, I am in need of a VI that can convert a standard Labview Timestamp used ion a Labview VI that when exported to Excel via a tab delimitted text file or some equivalent will be recognizable by excel as a timestamp in its cells.  Has anyone gotten this done?

Excel will actually format time in as many ways as LabVIEW to accomodate local preferences.  Under the hood, Excel stores times as a floating point number with the integer being the day and the fraction the fraction of a day.  The epoch is January 1, 1900 = 1.0.  In addition, due to a variety of interesting historical decisions, Excel assume 1900 is a leap year, which it is not, adding an extra day to the number for dates from March 1900 forward. A web seach will give you a plethora of information, such as this link.
LabVIEW formats time as the number of seconds since midnight January 1, 1904 GMT.  The timestamp data type is a 128 bit fixed point number with the decimal in the middle (64-bit integer and fraction).  Converting from LabVIEW's internal format to Excel's is left as an exercise to the reader, although the solution has been posted on these forums more than once .
However, as James W said, it is probably easier to format to a text string and use that.  This requires no action in Excel, whereas the converted number would need to be formatted to a date once imported to Excel.  You may have trouble with time zones, however, since I believe Excel uses local time, but LabVIEW uses GMT.

  • Excel auto formats cell in CSV flat file.

    Hi,
    I am using an etext template to generate a CSV file (comma separated) and that piece works fine. But as soon as you open the generated file in Excel, it changes the format of one of the columns to a date! And once you have opened it in Excel, saving it changes the column value, so now I have wrong data!
    The field value is : 8050-09-7 (Alpha)
    When opened in Excel, it becomes: 9/7/8050 (Excel auto formats it)
    If I save the file as a .xls file and not a .csv file, it works, but now when I open it, the entire row shows up in one line in Excel and each field is not in each cell.
    The user wants to see the output first, verify the data and save it as a CSV file and export it to a vendor software.
    Any ideas?
    Thanks,
    Shaf

    Hi Steven,
    I think I understand what you are trying to say.
    My data is getting generated initially as XML; I merge it with my eText template to get the final output. If I save the output as .txt, its fine. But users have a hard time reading comma delimited lines, though it will work fine for the customers.

  • During export from Discover to Excel, Time Format changes to Number Format

    Hi
    I have a seconds column which is of number datatype. But in my report, I am converting the number in *0HH:MI:SS* format. For example, I have *4952534 seconds*. So my report is showing *1375:42:14* which is a Time Format. It looks good when I view the data in Discoverer Viewer or Plus. But when I try to export the data to Excel, the time format gets converted to *4952534 seconds*, which is creating problems. So can you suggest on how can I preserve the formatting during export to excel from discoverer.
    Thanks
    Sachin

    Hi,
    Excel will not implement the 0HH:MI:SS data format, it just gets the field as a number. You will have to format the field into text using the calculation from my previous post.

  • Cfspreadsheet breaks Excel's "Format Cells..." functionality?

    Hi everyone,
    I am working on moving a CF7MX project to CF10 and one of the changes involve updating some code used for generating csv files so that it makes use of the CF spreadsheet functions.  One thing I noticed was that I can no longer use the "Format Cells..." functionality with xls files generated with the CF spreadsheet functions.
    If I try it with any other file it works like a charm, but with these CF generated files clicking on the button shown above does nothing.  Is this a already bug known by Adobe? Is there a way to make this work?

    Hi Riddhi,
    When you preview the dashboard in Xcelsius, Flash is used and SWF file gets created; however, snapshot shows you the excel data.
    The issue could be specific to Excel version or the data coming from web service need to be checked.
    Can you simply hardcode some date values in Excel (without taking them from web service) and try to change their format? Does it work fine. It help to understand on exactly the problem exist.
    I would also suggest you to check the format coming from the Web - service. In order to do so, you can use some third party tools like Fiddler or Charles Debugger.
    Hope it will help.

  • I want to add 1 minute to my month, day, year, and time format cell

    I have a table that I need to change the initial start time by 1 minute every 4th line item. What formula would I used to do this? Example:
    September 27, 2012 10:00 AM is the Start Time and is used for 4 line items
    The next 4 line items will be at 10:01 AM and so on throughout all of the line items
    I need a formula to do this and can't figure it out.

    Here is something that might work:
    Use a table (called "Setup") to set the start date and time, then in a second table refer the set up date and time like:
    A2=DATE(YEAR(Setup :: $B$1), MONTH(Setup :: $B$1), DAY(Setup :: $B$1))&" "&TIME(HOUR(Setup :: $B$1), MINUTE(Setup :: $B$1)+INT((ROW()-2)/4), 0)
    select S2 and fill down as needed

  • Conversion from Excel time to labview time

    Hello all,
                                       I want to convert the excel time stamp to labview time stamp. Can you all please help me how to do this ?
    In my application labview time is 05-11-12 14:56:00 and its equivalent excel time representation is 41218.6222222222.
    I tried this formula,
    Labview time =  24*3600*(Excel time - 1460) but anwer is wrong.
    Thanks.
    Kudos are always welcome if you got solution to some extent.
    I need my difficulties because they are necessary to enjoy my success.
    --Ranjeet

    Ok, here's what I found.  The conversion is:  Time Stamp = 86400*(Excel Time - 1462).  But here's the kicker: the timestamp is GMT.  You have to add your time zone offset as well.  I'm in the Eastern Time Zone, so I had to add 5 hours.  I'm not sure what DST will do to this.  I'm sure there's ways around it, I just don't have time to look into it more right now.
    There are only two ways to tell somebody thanks: Kudos and Marked Solutions

  • Quickview displays wrong "time" format of Excel document

    Here's an odd one. I have an excel document that has a row who's number format is time. Data entered and save the document. Look at the document in the finder under quickview and all the times are +3 hours. This happens in both Excel 2004 and 2008. It also happens on both my Powerbook and G5 tower. Both PPC. Both 10.5.1
    Can anyone re-create this, or is it just me?

    Hi,
    There is no error from the CRM functionality. If you SAVE the excel,instead of opening it directly and then " open with "
    word pad or notepad, you can see the phone no.s and fax no.s are properly transported to excel.There is a default format setting of
    excel from the Microsoft, so you are getting the default format after opening the excel.
    Steps:
    1.Export to excel.
    2.Choose the BP,PHONE and FAX columns holding the 'CTRL'key.
    3.Right click on the chosen columns and choose "format cells".
    4.Under the tab "number" choose 'number' and and reduce the decimal
    place to '0' and click "OK".
    5.Now you will be able to see the expected format.
    If you are using IE then the excel file that is being generated should be an XML file which would help with the formating issue. But when there is a problem in the generation of the XML file a CSV file is created instead.
    The kind of problems that can cause this could be :
    - Wrong version of Excel (professional needed)
    - Error in encoding (note 1560243 corrects this)
    - Active X Settings on browser are not properly setup or disabled
    - Other problems (some fixed in note 1457261)
    I hope this helps.

  • Export to excel with formatting was autowrapping text in a cell

    Export to excel with formatting was autowrapping text in a cell without having to check the can grow option.  When the can grow option is checked it does wrap the text however it spans multiple rows, which causes complications when trying to sort. 
    It worked in:
    ProductVersion=10.0.0.533
    ProductName=Crystal Enterprise 10 Embedded
    Doesnt work in:
    Crystal Reports 10.0 Service Pack 6
    After the upgrade the reports did not autowrap, b/c the "can grow" option was not checked.  I believe this was fixed by "ADAPT00305137 Patch ID: 36479914
    Description:
    When users export to Excel 97-2000 with the page-based format, text fields are wrapped, even when the "can grow" feature in the
    Designer is turned off." .   After we turn the option to grow on it does wrap however it spans across multiple rows.  So I guess my question is there a way for it not to span multiple rows when wrapping text?

    I could be wrong, but I believe the export to excel option exports the database values, and the export to HTML exports the values seen in the sheets. If the database values are stored as seconds, the Excel will see them as seconds, and the data will have to be formatted properly in Excel.
    I haven't toyed around with Excel exports that much, but it might be possible to set up a template or macro in excel that would have the proper formatting, and use it when opening the Disco export.

  • Will an Excel file retain formatted cells as a PDF using Acrobat XI Pro?

    Can Acrobat XI Pro create a form that will retain Excel formatted cells for filling in?
    Also, can it create a fillable cell that accepts an actual written signature?

    You will need to set the form in the PDF.
    Facsimile signatures are acceptable for legal purposes. You need to use a digital certificate that 3rd parties can verify but they maybe able to contain a signature image.

  • I would like to format cells with time only.  when I enter a time of day the current date is still in the cell which is not necessarily so

    I would like to format cells with time only.  when I enter a time of day the current date is still in the cell which is not necessarily so.  THere are  no options for just  date .

    christine275 wrote:
    ... (this is a time worked by date and not always entered on the date worked)--
    "Time" in Numbers is always "Time of Day", and is always part of a Date and Time value. "Amount of Time" is a Duration value, which may be displayed in a similar format to "Time of Day," but is a different type of value.
    If you are entering the number of hours and minutes worked, format the column as Duration, set the units and the format in which you want to have the value appear.
    The Date column will still contain a Date and Time value (Jan 1, 2011 00:00:00 in the cell shown in the example), but the "Time Worked" cells will contain only a Duration value.
    Incidently, the Date in A2 was entered as "jan 1" (without the quotes). Numbers automatically adds the current year and the default time value, then displays the result in the closest format to what you've entered, or in the Date and Time format you have chosen.
    The Duration value in B2 was entered as 3:15 (as displayed). Note that in the entry bar the duration is displayed as 3h 15m, probably to distinguish it from a similarly formatted (Date and) Time value.

  • When i paste some copied color text or formatted cells from excel to my mail draft while composing a mail, it is being pasted as plain text. No back groud or text colors are copied to it. Please suggest a possible solution for this issue.

    Colors & Formatted Cells from Excel application can not be copied to my mail composer as it is. Only Plain text is copied.

    Wish I could be king. But you described the problem perfectly and I am still but a pawn. All I can say is that I trashed the mail preferences (com.apple.mail.plist) on my Mac Mini, and now my MacBook seems to work right.
    Sorry. :>) But that is the truth... The MacBook now has actually sometimes displayed pasted text in its actual, different, font and style as I paste it into a partially composed new mail message.
    In other (more rational) words, the problem seems to be tied to pasting only certain types of text. I have not been able yet to pinpoint what. Yes, frustrating indeed. The only work-around has been to re-train my fingers to command-option-shift V, for "paste and match style" (like you, I do not want to always use only plain text). Maybe someone else will eventually weigh in with a real solution. The solution I want is just to be able to consistently see any font variations within my message before I send the email.
    The info about the different ppi scales between Windows and Mac is interesting, although not relevant to this particular problem. It does explain the apparent overall size differences I have seen before.

  • Can I Write Data to a *.xlxsx File Without Screwing Up the Excel File Formatting?

    I'd like to programatically add LabVIEW-generated data to a nicely-formatted *.xlsx file, one with all the right borders and column widths, etc.  But every time I try to add the LabVIEW data, the xlsx file formatting gets all screwed up and the file gets corrupted.  Is there a way around this?
