Read lvm file in excel

Hi.
How do you open and read a lvm file in excel spreadsheet?

The hardest problem is just seeing it. In the File of type field in the file dialog, select All Files (*.*). Navigate to your file and select it. Excel will correctly interpret the LVM file as a text file and import it. If you use the default settings (tab separator), just hit the Finish button and it will be imported.
NOTE: An LVM file can easily be longer than Excel can import. I haven't tried, but I think it will just truncate the file with a warning.

Unable to read the file in excel..

Hi all,
I created a report.for this report It was an excel template. when I click on view button I am getting an error Unable to read file.
I checked my query in database it retrieving 43000 records.
When I am going for rownum<1000 my report is giving successful results.But when I am removing that condition in where clause I am getting error Unable to read file.
Can any one pls help in this.....
Thanks,
KSS.

Not that this really answers your question but... 45K records seems like a lot of data. Perhaps you need to add some conditions to your SQL to limit the records to a more manageable size and make the results more relevant to the task. Just an opinion.

Problem in Reading XLSX File (MS EXCEL 2007).

Dear All ,
I am reading all the properties to XL sheet and then utilising it in my code .
I am getting some problem in reading the Border of the Cell , my code is working fine with most of the Excel Sheet but it can not correctly read the Border of a few Excel files.
I am using the method ,
getBorderBottomEnum()
or
getBorderBottom()
but I can not read the Border used correctly for all the Excel Sheet .
Please Help.
Please revert if I am not clear.
Thanking You All.

I'm guessing that your question is about Apache POI. They don't have a forum AFAIK, but they do have a [url http://poi.apache.org/mailinglists.html]mailing list.

Problems with displaying read data from a .lvm file

Hi all.
I aquire data with the PCMCIA card 6036E. I aquire online in Labview 7 and store the data in a .lvm file. When i try to display the same data i aquired before with the "read .lvm file" express vi, the waveform chart redraws itself after an undefined time, sometimes it redraws faster and sometimes it takes longer. WHY? i have only one header per aquisition and if i restart the aquisition a new file is written! I tried almost everything. Is this a bug from labview 7?
I really appreciate your help.
best regards,
Bernd

Hi Khalid,
Here is a simplified version of my VI and also 2 .lvm files from the logged data. Sorry for the size, but I aquire with a sample rate of 20 kS/s and my main frequency is only 0.3 Hz. In the 6MB file I aquired a little more than 3 periods. When you run the VI with this file at the beginning it redraws very often and very fast, then after some time it draws about 1 period and then it redraws again and so on. I want that the hole data from this file is displayed at once. The 900kB file is aquired with 10kS/s and about 1.5 periods. This is the last size the displaying is working with. You think it is possible that the VI only works until 1MB? But my data usually is much bigger than that. I hope you can use the data because it is
zipped, but otherwise it wouldnt be possible to post it.
Thank you very much for your help, I really appreciate it!
Best regards,
Bernd

Can i open lvm file in a Pocket PC emulator?

Hi all, can i open lvm/xls file in a Pocket PC emulator? I keep getting an error msg...
Thanx!

I was wrong. It does not appear that PocketExcel will open an LVM file, at least not in Windows Mobile 2003 on my Dell Axim X50v. However, there is a fairly easy workaround, if you have a copy of Excel (or OpenOffice, which is free). Open the LVM file in Excel, save as an Excel binary (XLS) file, then drag the Excel file to your synch folder. ActiveSync will convert the XLS file to pocket Excel format on transfer. You can then open it in PocketExcel. You can use ActiveX to save directly to an XLS file, or use the report toolkit to make your life a bit easier.
It is possible that you can do this, since I am a fairly new Windows Mobile user. I tried a simple copy of the LVM file and tried changing the file extension to .txt. I could not get PocketExcel to even look at it, although, as you mentioned, Pocket Word opened it with no problem. Diving into the documentation did not help much either. If anyone else having a bit more experience has a better solution, I would love to hear it.

Spectral analysis with 10 averages using 10 lvm files

Hi
I would like to create a spectal analysis of some results i have saved in lvm files in labview 7
is it possible to use the averaging option in the spectral measurement function to do 10 averages if i read 10 lvm files
ie.
Read lvm file #1
do spectrum analysis
read lvm file #2
redo spectrum analysis and average results between file #1 and file #2
read lvm file #3
ect
Thanks in advance
Mark Thompson

hi there
you can swop the order of calculating the average and the FFT. So first read all lvm files, average the time based data and then do the FFT over the averaged data.

Read several 2D Arrays out of lvm file

Hello,
for my data aquisition, I join three 1-D Arrays to a 2D array. I then save several of these 2D Arrays to a lvm file, until it exceeds 500kb. Here I ues the "write to measurement" express VI. When I'm trying to read the data I encounter a problem:
the "read from measurement file" express vi, seems to only give out the first 2D Array, that is in the file! Each 2D Array holds 75 values for every channel. I checked the content by dragging and dropping the file to Excel and the notepad. I can then see all the arrays, I saved in the file, and not only the first one. I tried to adjust the options in the "read from measurement file" VI as well, but nothing seems to help.
I attached an example lvm file and my reading VI.
It would be very nice if somebody could help

Hi
I'm not really sure which way you want to read out the data.
Do the different 2D Array all belong together, meaning that the 2nd array is just a continuation of the first?
If this is the case, you could select "Segment Headers">"No Headers" in the "Write to measurement file" VI.
Then, in the "Read from measurement file" select: Read generic text file, and set the parameters accordingly.
Use the "Read File now" function to test the set parameters.
Further you may have to change the indices for the Index Array in your VI.
However, this method has the obvious drawback of loosing the header information.
Alternatively, you can save the data in a tdms file, instead of a lvm file. Here the headers are handled better.
Select "One header only" in the write to measurement file. When your then read out the data, it automatically will read out all data.
And you keep the information of at least the first header.
If each 2D Array should be read out separately, you should use a different approach. Please let me know, if this is the case and I will explain further.

How to read the data from excel file and store into the table?

Hi All,
I have table with BLOB datatype contains a excel file. I have to read that data from excel and store into one table with all the fields in excel.
All the excel fields and my table columns are same.
Can you share with me how can acheive this using LOB's?

Hi OraSuirya,
you can try with external tables .
syntax as follows
create table ext_table_csv (
i Number,
n Varchar2(20),
m Varchar2(20)
organization external (
type oracle_loader
default directory ext_dir
access parameters (
records delimited by newline
fields terminated by ','
missing field values are null
location ('file.csv')
reject limit unlimited;
For this you need to create directory
Directory Creation syntax:
create or replace directory ext_dir as 'D:\oracle\user_dir\ext_dir';
grant read, write on directory ext_dir to <User>;
please paste the excel file in the particular directory .
I hope this will help you.
Please correct me if I am wrong anywhere .
Thanks,
Tippu.

You might want to look at the POI project (an open source Jakarta sub-project) that allows you to create/modify/read excel files via Java code. That might be more flexible and easier than what you're currently trying to do.

Help! How to read data from an Excel file?

Hi,
I need to read data from an Excel file that may contain more then one table in a sheet. How can I read them?

Did you try POI from Apache?

How do I read my wave form data back from an LVM file?

I collected a waveform and saved it using the LVM file format. I would like to read the waveform back into labview and display it with its timestamp and assigned name. The only way I could read the data back into Labview was to convert it to a number array. I figured if you could write a waveform and save all its data, you should be able to read it back rather easily. I've included my LVM file and two simple programs. The program I'm using is much larger, but these two programs are representative of what I'm trying to accomplish.
Thanks

Hi Knoebel,
To display the waveform data, you'll need to change a couple things.
1. Open the "Convert from Dynamic Data" vi and change the Conversion to have a resulting data type of 1D array of waveform, as this is the datatype you are writing with the "Write To LVM.vi" Currently you are converting to an array of scalars here, which is why you are losing timestamp data.
2. Open the "Read from Measurement File" express VI and Change the Time Stamps to be Absolute (date and time) rather than relative.
3. If you want to display the timestamp on the waveform graph, pull up the properties window for the Waveform graph and change the Display Format to be Absolute Time for the X-axis and then check the Scales tab to be sure you have unchecked Ignore waveform timestamp on x-axes
After making the change to convert from dynamic data type to 1D array of waveform you can also probe the wire going into the waveform graph to check the t0 and dt values of the waveform as you read from file.
Lastly, if you look at the Write to LVM.vi block diagram, you will see a little red coercion dot between the waveform data wire and the Write to Measurement File data input terminal. It would be better to use the "Convert to Dynamic Data" express VI to make this conversion.
Hope this helps!

Reading long text from excel file to an internal table

Hi
Can any body tell me how to read long text from excel file to an internal table.
When i am using this FM KCD_EXCEL_OLE_TO_INT_CONVERT then it is reading only 32 characters from each cell.
But in my excel sheet in one of the cell has very long text which i need to upload into a internal table.
may i know which FM or what logic i need to use for this problem.
Regards

Hi,
Here is an example program. It will upload an Excel file with two columns. You could also assign the Excel structure dynamically, but I wanted to keep the example simple. The main point is that the internal table (it_excel in this example) must match the Excel structure that you want to convert.
Remember, this is just an example to help you figure out how to properly use the technique. It will certainly need to be modified to fit your requirements, and as always there may be a better way to get the Excel converted... this is just one possibility that has worked for me in the past.
