Input values in table from external file and increment rows accordingly

Question

I am trying to create a report in table format and values in table have to input from some external file (or excel file). Can this be achieved in Latex? If yes, then the number of table rows should be auto increment according to input data. I tried using \longtablebut could not succeed. following is my code.

\documentclass{article}
\usepackage[a4paper,margin=0.7 in,landscape]{geometry}
\usepackage{array}
\usepackage[thinlines]{easytable}
\usepackage{geometry}
\usepackage{fancyhdr, graphicx}
\usepackage{tabulary}
\usepackage{fancyhdr}
\usepackage{lastpage}
\usepackage{multirow}
\usepackage{longtable}
\usepackage{float}
\usepackage{ltablex} 
\pagestyle{fancy}
\setlength\headheight{30pt}
\fancyhead[L]{\begin{tabular}{lll}
          %  \hline
            \multirow{2}{*}{\includegraphics[width=30pt]{logo.jpg}} &          \multicolumn{1}{l}{\textbf{Variable Messsage Sign Report}}  \\
                             & \multicolumn{1}{l}{Downloaded by USER on DATE and TIME}  
\end{tabular}\\}
\cfoot{\thepage\ / \pageref{LastPage}}
\renewcommand{\headrulewidth}{0.4pt}
\renewcommand{\footrulewidth}{0.4pt}

\setlength{\@fptop}{0pt}
\begin{document}
