One embedded excel for multiple charts in PowerPoint - excel

I have a ppt with 80+ charts in 50+ slides.
When I get the data, I've to go into each chart -> right click -> Edit data -> Update the data in the embedded excel.
This process I'm repeating 80+ times for each chart which is time consuming.
I'm aware that the ppt can be transformed into a complete excel pack where we can have all the data in one single sheet and link to multiple charts in different tabs.
But, Is there a possibility in ppt itself to keep all the data in one embedded excel and refer it to all the 80+ charts?
Really appreciate any help on this!!
Please let me know if you have any questions..
Thanks..

X axis disappears in charts liked from Excel to PowerPoint

I have a problem that I cannot figure out how to solve. I have an excel file containing some charts and I have PowerPoint file. All of them are located in the network and not physically on my PC.
There is a UI where users can select what they need and then through the code behind the PowerPoint gets populated automatically with the charts and data contained in the excel file.
There are about 30 pages in the PowerPoint and in only 2 of them the X axis of the charts disappear and cannot figure out why:
I recreated the charts and the sheets entirely that contained those charts
tried to work on the size of the charts at excel file level and by setting the X axes "below" the plot
I clicked on the locked ratio option of every chart in Excel and updated the links again.
The PowerPoint template file gets updated correctly but when a user run a query and then the powerpoint is generated on the basis of the template, the resulting powerpoint has these 5 charts but without X axis.
Please let me know if someone has ever faced this kind of bug/problem.
Thanks

VBA excel charts and tables to PowerPoint specific pages

I’ve been trying to do this using my very limited coding knowledge. But how do I copy paste particular charts and tables in my excel sheet onto particular pages in my presentation?
Some need to be copied as pictures but most as chart objects.
Thank you in advance!!

Extracting certain Powerpoint slides based on an Excel table and combine to new presentation

I have a huge PPT presenation (>400 slides) and want to extract certain pages based on an Excel table and create a new, smaller presentation.
I created an Excel table which includes the page numbers as well as the title of each slide in the PPT presentation.
The goal now is, to have a macro that allows me to create a new PPT with all the slides that are mentioned in my (sorted) Excel table.
As I am new with VBA (I am only able to copy/paste code and run it afterwards), I was not able to try anything.
Thanks for your help!

Pre-populating PowerPoint file with Excel input

I am currently in the following situation:
I have an Excel file where I perform calculations and charts + diagrams are created based on the calculations.
I have a PowerPoint report where I have to copy-paste these visualizations into.
I will need to repeat this process for many Excel files, all containing the same lay out. You can view them as a questionnaire: each Excel file is completed with different answers, though the structure remains the same.
Is there a way for me to create a template PowerPoint report file, where at the start I select which Excel file to 'load', and it pre-populates my PowerPoint file with the correct charts from the selected Excel file?
ndeed, there is a free option available. With SlideFab 2 (lite) you can automate Excel to Powerpoint without coding: You would need to setup the Powerpoint template and link all shapes with the required Excel ranges or charts. Then SlideFab creates the slides for you. When the structure is really the same, you could just let SlideFab connect to the next Excel file and rerun the slide-making process again.
You could also consider using RDBmerge to collect all workbook sheets into one Excel and using formulas to create a kind of staging area which is used for linking with Powerpoint. This would have the benefit that when you iterate a list of worksheet names, your lookup (e.g. using vlookup or index/match) functions would grab the appropriate data into the staging area. SlideFab could then create all slides at once through changing the selected worksheet in a repetitive way.
In case of questions, feel free to reach out.

Excel charts and graphs automatically updated with new raw data

Looking for advice and suggestions on how to build this out...
I am exporting raw data from a data source and pasting it into Excel. The data source cannot directly connect with Excel (hence pasting it in). The data is used to populate a bunch of charts and graphs, similar to a dashboard. The raw data will change depending on the data request. Instead of rebuilding all the charts and graphs, I'd like to paste the new data into the Excel workbook and refresh all the charts and graphs. What is the recommended approach?
I'd appreciate any suggestions. Thanks!
