Copy and Paste Data from Multiple Worksheets into one Worksheet

Hello,
I have a project that right now requires a lot of copying and pasting of similar data sheets into one master sheet. When my data is exported from our accounting software, each “lot” is exported onto a separate sheet. I may have up to 100 sheets in one workbook.
The data exports into Excel in a very predictable format with the columns and data always aligning (data range is always between A:H for example). The trick is the number of rows will always change with each “lot”.

I would like to get a macro that will find the range in each sheet and copy the data onto a “master” sheet, then go to the next sheet, find the full range copy that data and then paste to the master, below the previous data. It would continue to do this until it has copied it from all sheets. I would put the Master sheet on the left and then have the macro move left to right looking in each next sheet.

For example of the output, See the attached workbook and the “Master” sheet.
The copy and paste does not have to be pretty as I can clean the data later. But all the data on one sheet, with the columns lined up is my goal.
Any feedback helps. Thank you in advance.

Hey JLGWhiz. Thank you for such a quick reply. I tried the macro but it throws a Run-time error '91': Object Variable or With Block variable not set. I've attached the model. The error may be on my end. I put it in Module 1 but unsure if I did it correctly. Thank you again.

Hi Again JLGWhiz,
I was able to get it to run, but only partially. It seems to skip some sheets (not sure why) and some sheets it only returns the last row. What is also peculiar is that it starts populating the Master sheet on row 26. I've attached the full workbook I am using with confidential info removed so you have a better idea of what I am working with. Thank you again for your time.

It works! That is a thing of beauty! Thank you for all your help!
