 ### A Word about Harmonized Data Formats
 
-Above, we've discussed several aspects of selecting a **data format**. There are at least three related, but not exactly equivalent, concepts to consider when formatting data. First, formats describe the way data are structured, organized, and related within a data file. For example, in a tabular data file about biomass, the measured biomass values might appear in one column, or in muiltiple columns. Second, the values of any variable can be represented in more than one format. The same date, for example, could be formatted using text as "June 1, 1977" or "1977-06-01." Third, format may refer to the *file format* used to hold data on a disk or other storage medium. File formats like comma separated value text files (CSV), Excel files (.xlsx), JPEG images, are commonly used for research data, and each has particular strengths for certain kinds of data.
