      This package contains VIs for reading and writing to CSV files that follow the CSV format outlined in RFC-4180 (see http://tools.ietf.org/html/rfc4180). Using this package, you can properly import CSV files that were exported from spreadsheet programs such as Microsoft Excel, Open Office or LibreOffice Calc as well as export CSV files that will be compatible with any program capable of interpreting CSV files.
      This implementation of the CSV format is capable of handling escaped fields such as those containing commas (or other field delimiters), multiple lines, and double quotes.
      - Starting from V1.1.0, library files are located in "<LabVIEW>\vi.lib\LAVA\Robust CSV" and example is located in "<LabVIEW>\examples\LAVA\Robust CSV".
      Development version available on GitHub: https://github.com/rfporter/Robust-CSV

      My project involves designing a front end for a synchronous generator using LabVIEW.   It is actually data acquisition and display of signals in a file.   The problem I face when building a program is that:   1)the sampling rate is set to 100 samples with 1 kHz sampling frequency.These signals are generated by daq assistant and i have used merge signals to merge these signals from daq assistant as well  as signals from other radio buttons and Boolean as well. The problem is that when written on a file I am able to see only one instance of Boolean status for every 100 samples daq assistant creates.   2) now iam able to write only 0/1 as status of Boolean in the file.How will I write on /off into file?

      Hello Labview Users, 
      I happen to have thousands of csv data file that I work with. The only way I recognize them is putting their characteristics in the file name. Which brings the problem of making the names too long and Microsoft doesn't like to accept long name. So I wanted to build a database for all my files. I am in the preliminary stage of building it ( I have attached the file and some of you may have seen it before). 
      What I want to do is, have all my files in the database with random names and list them based on their characteristics. I want to do that in my application in the place of 'file' box. So that I can click on the file and run it (double-click on the file in application to make them work in active file). based on the parameters listed on the database I want to filter them to find any specific file. How the interface of database should look like is shown blow (Image) . 
      It doesn't have to be a real database, just a directory application. I am trying to make it without the database toolkit.  If anyone can help me out and guide me out or guide me in the right direction then that would be great. Thanks.

      Hi All,
      I am a new user to LabView and this is my first project using it. The project requires me to read a massive spreadsheet from Excel into LabView and then allowing the user to do the following:
      - Select which columns to plot against the first column
      - Use a cursor to select a portion of the spreadsheet: the Vi will then average the selected data by column (in other words, if the user selects data across multiple columns, the program will average data in each column separately). Then write the averages to the csv file.
      So far, I have the spreadsheet read into a table as strings (because the first row of the spreadsheet is words). I have spent a lot of time searching how to allow the user to select data on the table to perform operations on, but to no avail. I am hoping you guys could give me some insight on how to tackle this project.
