TriLookup
TriLookup Add-In for Excel
TriLookup is an add-in for Microsoft® Excel for Windows versions 97, 2000, 2002 (XP), 2003, and 2007 and Excel for Macintosh versions 98, 2001, X and 2008. When installed, TriLookup adds eleven powerful lookup and interpolation worksheet functions to Excel, which offer greatly enhanced functionality compared to Excel's built-in lookup functions. You can use them to perform simple table lookup, as well as, interpolation and extrapolation from tables with one, two or three independent variables.
The animated chart on the right shows a series of 3D surfaces plotted
from the values returned by the T3LOOKUP function. Each individual surface
in the series is calculated for a constant Z value.
TriLookup is Shareware, i.e. you can test the fully functional evaluation version for 30 days. After this trial period, you must register or delete the program from your hard disk. You may also freely redistribute this program. See and TriLookup Software License and Registration for further information.
The evaluation version of TriLookup is fully functional and differs from the registered version only by displaying "TriLookup splash screen" every time you start Excel.
