You can create folder, file or path, write and read data by using the **File I/O** VIs and functions (**Figure 37**). LabVIEW allows you to save data with different data

*Write Delimited Spreadsheet.vi* converts a 2D or 1D array to a text string and writes the string to a new byte stream file or appends the string to an existing file. Both 2D and 1D arrays can be strings, signed integers, or double-precision numbers. You should put **Write Delimited Spreadsheet.vi** out of the loop (**Figure 38**). Putting the VI inside the loop is not the good way of using it. Because LabVIEW at every iteration would open-write-close the file if it is inside the loop. This is not

You can also write date/time information for each data point. In the following

*Read Delimited Spreadsheet.vi* reads a specified number of lines or rows from a numeric text file beginning at a specified character offset and converts the data to a 2D, double-precision array of numbers, strings, or integers. In the following

example (**Figure 39**), data consist of time and random number.

In the following example, we use **Report** Express VI to present data in html format (**Figures 35** and **36**). You can also send data to printer or present data in MS Office Word or Excel format with the same VI. To do this double click **Report** Express VI and select the corresponding line from **Destination** tab in **Configuration Report** window.

When you execute the VI above you will see the following report.
