The basic formatting of this file is simple. The first row will contain unique column headers that are tab-delimited (i.e. separated by tabs). The first column of the data, by default, is assumed to be the column that contains the depth reference for the data in the row. Every row of data is also tab-delimited, and must contain the same number of tabs as the header row; in order to positively determine which data value belongs to which column. Microsoft® Excel can export a worksheet as a tab-delimited file in the same way. An empty entry is considered to be two consecutive tabs, and will be dealt with properly. Any data that appears to be invalid should be deleted in your spreadsheet program of choice to create an empty entry.

Depth [m]	Porosity [% vol]	WBD [g/ccm]	Sus [units]

12.270			245.60
12.290	0.420	1.995	244.68
12.310	0.408	2.015	257.45
12.330	0.365	2.087	280.15
12.350	0.387	2.050	305.97
12.370	0.383	2.057	390.86
12.390	0.434	1.971	620.38
12.410	0.282	2.226	762.53

NOTE: In this example you can see that on the third row there are two blank entries for both Porosity and WBD columns.
