Extract, Convert, and Merge 'pdf' Files from 'zip' Files

Extracts 'zip' files, converts 'Word', 'Excel', and 'html'/'htm' files to 'pdf' format. 'Word' and 'Excel' conversion uses 'VBScript', while 'html'/'htm' conversion uses 'webshot' and 'PhantomJS'. Additionally, the package merges 'pdf' files into a single document. This package is only supported on 'Windows' due to 'VBScript' dependencies.

LJexm

LJexm is an R package designed to automate the process of extracting ZIP files, converting 'Word', 'Excel', and 'HTML/HTM' files to PDFs, and merging PDF files in a structured order.

Manually Checking Errors (If Needed)

If you need to check errors manually before running the script, you can view the log file:

log_file <- file.path("path/to/your/folder", "conversion_log.txt")  
if (file.exists(log_file)) {  
  log_content <- readLines(log_file)  
  message(log_content, appendLF = TRUE)  
}
