Batch File Search and Renaming with VBScript
If it is necessary to rename a batch of files, where both the existing and new file names exist in an Excel spreadsheet, VBScript can be used to automate the renaming process.
In the example below, a spreadsheet called “Documents to rename.xlsx” contains the file name information. Column ‘A’ contains the existing file name, without the file extension, column ‘B’ contains the new file name, if available, without the extension, and column ‘C’ is for notes to be added during the renaming process.
|Existing File Name||New File Name||Notes|
First of all, the path to the above document, as well as to the files to be renamed, is set and a check is made to see if they exist. If they do exist, the document containing the file names is opened and the file name information on the first sheet is processed. The last row used in column ‘A’ is obtained and all the rows, from the second to the last are handled one by one. The current and new file names are extracted from columns ‘A’ and ‘B’, using their numerical references, 1 and 2. A check is made to see if the file exists with the current name and if it does the file gets renamed to the new name, providing there is a valid one available. Feedback is added in Column 3 as to whether the file was renamed or not, or, if it had already been renamed. Overall feedback is also given as to the total number of files renamed.
