eXPFit Peak Fitting Add-In for MS-Excel
eXPFit is a peak fitting utility running under Microsoft Excel. It has been specifically set-up for the analysis of X-ray photoelectron spectroscopy (XPS) data, but could be used to fit other types of spectroscopic data.
This software is suitable for those people who commonly use Excel for manipulating data and assumes a certain familiarity with Excel. Within these constraints it provides great flexibility, but if you want a completely robust, user-proof or computationally-efficient peak fitting routine then you should look elsewhere; this software makes no pretence of meeting any of these requirements !
