ExcelSheetUnhide is a powerful tool developed to Unhide Hidden Excel Sheets. The script operates by launching the targeted Excel file within an automated Excel editor as an object, providing a means to enumerate and subsequently reveal hidden sheets and workbooks.

ExcelSheetUnhide is not static and runs the Excel file because of how the Application’s ComObject works. The script uses the “AutomationSecurity” application property (set to 3) to turn off all macros before and after opening the file. Still, it’s best to use this script in a virtual machine environment because of its dynamic nature.

ExcelSheetUnhide Usage, Syntax, Examples

To Unhide Hidden Excel Sheets using ExcelSheetUnhide, follow these steps:
1. Download the “ExcelSheetUnhide.ps1” script from ExcelSheetUnhide GitHub page
2. Run PowerShell console.
3. Make your way to the directory containing the “ExcelSheetUnhide.ps1” script using the cd command.
4. Run the script to check the help notes. You can also use the -h switch to access these notes. The notes contain all the information needed to Unhide Hidden Excel Sheets effectively.

Before you proceed with the script, it is prudent to check for hidden workbooks. The -c and -in switches facilitate this process. The -c switch triggers a check for hidden workbooks, while the -in switch is used to specify the full path to the input Excel file.

.\ExcelSheetUnhide.ps1 -c -in "C:\YourMalicious.xls"

Identify the hidden sheets or workbooks in Excel and then unhide them. The -u, -v, and -l switches are integral. The -u switch is for unhiding the sheets, -v makes the Excel application visible, and -l terminates the script leaving the Excel application open.

.\ExcelSheetUnhide.ps1 -u -v -l -in "C:\YourMalicious.xls"

If you prefer not to interact with the Excel GUI, ExcelSheetUnhide allows you to Unhide Hidden Excel Sheets using a fully command-scripted environment. The Excel application runs in the background in this mode, using the -c, -u, -e, -f, -in, and -out switches. The -e switch exports the changes made by the -u switch to the Excel document, while the -f switch forces an overwrite of the existing output file. The -out switch denotes the destination file for exporting changes.

.\ExcelSheetUnhide.ps1 -c -u -e -f -in "C:\YourMalicious.xls" -out "C:\YourUnhidden.xls"

ExcelSheetUnhide is a powerful tool that can uncover Excel sheets, specifically those hidden by Excel 4 Macros. However, it’s important to note that due to the way it works, it’s best to use it in a secure environment to avoid any potential security risks.
