title: Filter Excel spreadsheet values from file
body: <p>I want to be able to filter column values in an excel spreadsheet from values of an external file. </p>
  
  <p>For example: Column A lists a bunch of programs running on a computer. I have a white-list of "approved programs" in a .txt or .csv file. </p>
  
  <p>I want to write a script that will delete entries from "Column A" if the cell contains a value matching one of the entries in the .csv file. </p>
  
  <p>E.g.: "Column A" contains hundreds of entries from "Adobe" to "Xerox". I have my list of "approved software" that contains Adobe and Xerox. I would like Excel to search for entries containing Adobe and Xerox from "Column A" leaving only un-approved software. </p>
  
  <p>For those wondering... I am getting my data from SCCM and I am trying to find a way to create reports for workstations with un-approved software. If there is an easier way than dumping it to an Excel Spreadsheet, I would appreciate the input. </p>
  
  <p>Thanks!</p>
