Oh dear. A lot of confusion according to the comments.
This does not produce a PDF file.
This is for merging Excel worksheets.

According to the software developer website this software is already FREE for non-commercial use.
(hence no need for a "giveaway" actually)
You can pay for a license if you deploy it for commercial usage.

As for merging Excel worksheets.
Formulas in merged worksheets still need to be edited to link properly.
And that means you DO need Excel in order to edit.

The description says it merges them into 1 WORKBOOK file.
Which means the different (merged) worksheets appear as various worksheets in 1 workbook.

What is so difficult about that?
Any Excel user can do that.

The idea is IF you do not already have Excel in your PC, then maybe this software is useful to you.

If like most of us, you already have Excel, then don't bother.

I was hoping this would do what the title indicates, but it doesn't come close. I have 5 Excel files with identically named sheets with mostly the same columns but a few have some additional columns (all columns have a header). I expected the output to be a single XLSX file with all the sheets from each file, and each sheet containing all the combined columns. All this does is create a single XLSX file with each sheet appended onto the same sheet, regardless of the column headers. This is absolutely malarkey...not even close to merging an Excel file. If you really want something that does what it claims, take a little time to learn PowerShell and then look at he ImportExcel module. It does this and SOOOO much more. Don't waste your time on this giveaway...it's just an exercise in uninstalling programs from Windows.

To the developer you have a design bug. You are putting the files emsound.dll and emlan.ini in a wrong location. You are currently installing them in the user wide %appdata% location NOT "%appdata%\em1104"

This means other applications just as badly behaved could interfere with the operation of this program by interfering with it's files.

e.g.
Source: "{userappdata}\emsound.dll"; DestDir: "{userappdata}"; MinVersion: 0.0,5.0; Flags: ignoreversion
Source: "{userappdata}\emlan,1.ini"; DestDir: "{userappdata}"; DestName: "emlan.ini"; Languages: "English"; MinVersion: 0.0,5.0; Flags: ignoreversion

into something like:
Source: "{userappdata}\emsound.dll"; DestDir: "{userappdata}\em1104"; MinVersion: 0.0,5.0; Flags: ignoreversion
Source: "{userappdata}\emlan,1.ini"; DestDir: "{userappdata}\em1104"; DestName: "emlan.ini"; Languages: "English"; MinVersion: 0.0,5.0; Flags: ignoreversion
for consistency with the folder name you use in "{commonappdata}\em1104" or C:\ProgramData\em1104\

And obviously make the program refer to the user specific private location of the files for writing and reading.

I watched the video at the top of the page and...found it colorful, but not informative. The speed of the video was so fast that there was no time to see "what" it was doing, much less understand what it was trying to tell me. If that's the best they can do to explain the product I think I'll skip it and use cut-and-paste instead.

The program either crashes or sends me "unhandled exception" errors. NOT a "must have" for me. Uninstalled.

Il n'y a pas besoin de ce logiciel.
Il suffit de faire Edition/Déplacer ou copier une feuille d'un autre classeur.
Et vous pouvez ensuite faire les liens pour actualiser les modifs dans les 2 classeurs.

Thank you. Looks like a super useful and specialized tool for Excel! Even though i don't work on Excel like i used to, or will need this Excel add-on now. I always come to giveawayoftheday.com and search their software to find useful apps like this when i need them. Usually means i have to pay for them but it is worth it if the software is valuable. It's just too bad there's no amazon type reviews for software, but that's a tough thing to implement since rating often vary by ability of the user as well. Either way, this software is pure genious and i wish i had known about it before.

A “ Must Have” program for everyone!!
