Update several ppt files from a single excel file - excel

I have several ppt files and a single excel file containing the same information. I want all ppt files to be updated automatically whenever I change the information in the excel file. The reason is that the information is changing regularly and I want to avoid that it has to be changed in all the files manually every time. Instead, it should be possible to update all the files just by changing the excel.
Do you know, how I could do this?
Thanks and regards,
Marius

Insert Data into Shared Excel file

I have a Shared Excel file stored on a NAS, and i want to insert some data from a csv into the Excel without the excel being unshared.
can i maybe share the excel file programmatically ?
I tried reading the excel with py pandas and then overwriting with the new inserted data,
but then the file isn't shared anymore, so my users that are still using the file won't notice the change and maybe they are going to save their current changes which would overwrite the inserted data,
i also tried using VBS but it didn't work because the excel is shared.
I'm looking for a solution which would allow my users to modify the file without overwriting the new inserted data.
is that possible ?
Thanks for your attention. I’m looking forward to any reply.

Reset Default Workbook Open options

I use VBA in Excel to pull data from different sources (mostly .csv and .xls/.xlsx files) and paste them into my data tables (in the same Excel File I have a data table for each specific data source).
Each of those files comes with different settings. I have created an specific VBA Macro for each of my data sources to process, remove and copy the relevant information of each individual file, and then I call all of the Macros from another Macro. The problem I'm having is that for one of the data sources, when using the Workbooks.Open method, I have had to set the parameter Format to "Nothing" (Format:=5). But this affects then the subsequent macros and therefore the following files are not processed correctly.
I know I have two possibilities: Either I call this macro at the end, after I've processed all the other files or; I set the Format parameter in all of my Macros to the one specific for each of the files configuration. However there must be a way to simply reset the delimiter to the default one used in my Regional Settings. Does anyone knows a solution?
Sorry if there's already a thread with this issue but I've tried looking for it and didn't find any.
Thank you in advance.

Docx4J Generated XLSX file is always corrupt

TL;DR: Excel Workbook generated by Docx4J always says corrupted but I can't determine what Excel doesn't like about the underlying XML, let alone how to fix it.
My use case is as follows:
I am trying to produce an excel workbook with charts and graphs automatically on a regular basis. Only the raw data will change but everything else will dynamically update as the raw data is changed.
So I built an excel workbook which has a number of charts and graphs being generated by a sheet of raw data. I am using it as a template. All values of the raw data are numeric. The intent was to use Docx4J to read this 'template' and to populate the raw data sheet, then save it as a new file whereupon opening will initiate the recalculation and the charts and graphs will update. Since I am new to Docx4j, I basically decided to do baby steps by first seeing if I could open and read the contents of the cells; which I could. So far so good. I also could change the values of the cells but I could only verify this programatically by writing out to the console the location and value before a change, then the location and value after the change (ex. A1=45 followed by A1=55).
My problem starts when I try to open the resulting file. It generates, looks to be about the right size but Excel claims it is corrupted. It does try to recover what it can, but ultimately fails and the workbook won't even open. For troubleshooting, I opened up the generated xlsx and confirmed all the various XML files that make up an xlsx file were present and readable so I am concluding either something is missing or some part of the XML coming out the other side is not what Excel wants. Further troubleshooting involved creating an empty workbook (no data, 1 sheet) as my 'template', opening it and then saving it back to the file system with a different name and simply trying to see if I could open it in Excel but no dice. This has me ruling out anything to do with my attempts to write or add data to the sheet.
Relevant Environment Information:
'template' workbook is being generated on a Windows 10 64bit machine
My docx4j code is executing on a Debian 10 Linux machine running OpenJDK 11.0.4
My version of Excel both to create the 'template' and open the copy is Excel for Office365
I am running Docx4J v11.1.3 but I also tried with v8.1.5(both cases I had to use the Reference Implementation of JAXB to get around a marshalling error when trying to save)
I did see another post on Stackoverflow here about an issue related to fonts in Linux environments so I made sure to install the MS TT Corefonts but it didn't help my problem.
I ran the entire unzipped directory through BeyondCompare and there are some differences but I don't know which are just artifacts of the two different OS' or even which differences matter. Mostly they are:
small differences in file size
boolean values showing as "1", "yes", or "true" but not the same way for both files
namespaces and attributes in one file but not the other
Sheet1 from my blank workbook, before and after
All ideas are welcome.
Please try the just-released docx4j 8.1.6, which fixes handling of xlsx files created by recent releases of Excel. This was https://github.com/plutext/docx4j/issues/389

Save logfile within Excel file using VBA

I am trying to develop a manner in VBA to track changes in a document without having to hide the contents in an extra sheet within a workbook.
I understand that if you change the extension of an Excel file to ".zip", you can access the Excel document as components sorted into directories. Is there a way to save and write to a text file within one of these directories so that I can access it every time the document is opened, without having to have the user drag a log file along with the Excel document?
Some facts:
When Excel opens the file, the file is blocked by Excel. There is no possibility to write to that file within VBA
You can store additional data into that file externally or after the Excel workbook has been closed
You would need to have code externally from the workbook to accomplish writing to that file after it has been closed. You may want to use VSTO or an oldschool Excel Addin.
you have to ensure that Excel will not destroy your changes when restructuring or repairing the file.
In the first run, your idea sounds very natural, to not use sheets from a programmer's point of view. You only have full control on Excel files when
you use external libraries (e.g. Spreadsheet Gear) or
you remote control Excel via automation.
you use openxml SDK for Excel
you use VBA
You could insert additonal information and take care that this information is not skipped by Excel.
When you want to do the tracking this way, I would suggest you to use an Excel Addin. There is actually no need for installation when using this kind of Addin. Attach to open workbook and close workbook events and ensure that all changes are written to the Excel Workbook after it has been closed. Certainly you would have to attach to all kind of other events to track all changes to the workbook. You may need to have in mind that there can be more than one workbook opened at a time.
Actually there are alternatives.
write your logging code in VBA or whatever fits
abstract away how your persist the code (e.g. use a data provider)
think about these two alternatives to store logging data:
You can save logging data in cells of excel. When using a "newer" version of excel, you have a limit of 1 million rows. You may want to implement a rolling mechanism that ensures that you never go over the border of 1 million records. (you may be dont want to track a million changes)
You can use the document properties to store you information as xml.
Last but not least, the most obvious: Why not using Excel's functionality of tracking changes? Understand track changes in Excel 2013

Update a csv file used by Quality Center with a macro

I have a csv files containing iterations that will be imported into HP Quality Center and used to perform automated testing.
Some of the data in these files must be updated every month and I have created a macro for each to do this.
I cannot keep the macro and the csv on the one workbook as QC does not allow anything other than csv files to be imported (not that I know of).
I realise I can import the macro each time but there are many csv files and many macros.
Is there some format or work-around that would allow me to keep the macro on the csv file, so when I open it I can just hit Alt+F8 and run the macro?
Save your macros in your personal workbook (personal.xslb), rather than in the individual data files. Then they will be available to run your updates on the csv files without being stored in the files.
