I am trying to validate an Excel file (Macros Enabled) with multiple tabs that imports Data from CSV files. After this I am required to validate the file. Upon validation it is supposed to generate a zip file.. However when I try to validate the file it gives me an error message "Modifications Are Not SavedUpload File Not Generated Cannot access ......(here it mentions a particular tab name from within the Excel file that I am trying to validate)".On this message there is button to click OK. On clicking OK it gives a error Microsoft Visual Basic error "Run-time error '1004': Method 'Range of object'_Global' failed. There are two active buttons on this message End and Help. When I click End it displays the Tab which appears in the first error message.
