LabVIEW Measurement Data File (.lvm)

The LabVIEW Measurement (.lvm) format is a text-based file format for one-dimensional data that you can use with the Read LabVIEW Measurement File and Write LabVIEW Measurement File Express VIs.

The .lvm format is easy to parse and easy to read when imported into a spreadsheet program such as Microsoft Excel, or a text editor such as Notepad. The .lvm format supports multiple data sets, grouping of data sets, and the addition of data sets to existing files.

The file format is not designed for high performance or for very large data sets, as is the case with all text-based formats.

Note  For very large data sets, use the binary file format.

For more information about the .lvm file format, refer to the specification at NI Developer Zone.
