I am trying to copy an Excel workbook with 4 worksheets (tabs) where 1 worksheet is macro enabled with many formulas using the OpenXML SAX approach as I have lot of data for each sheet.
If I copy the file and and start writing into the worksheets, it starts writing from the 1st line and the headers are being deleted. So I tried copying just the macro-enabled sheet and add other sheets later and add styles to headers.
When I try doing it, the system give an error saying only one style sheet is allowed. Only one instance of the type is allowed for this parent.
How can I access the existing stylesheet and add more styling into it for other tabs?

I have scenario where I have to prepare two batch of excel files. I have two templates. I am automating a process. The 1st Excel file has formulas in it. I populate data using C# winform and OpenXML library in the first excel file. I want to have the formulas calculate results and then grab them to populate the 2nd excel file. I have tried various methods but was unsuccessful. I did use the following code hoping it will make the excel file calculate the formulas in it.
SpreadSheetDocument.WorkbookPart.Workbook.CalculationProperties.ForceFullCalculation = true;
SpreadSheetDocument.WorkbookPart.Workbook.CalculationProperties.FullCalculationOnLoad = true;
So basically the process should be
Make copy of the 1st excel file and populate it with data [This part is working]
Some how make the 1st excel file data calculate the formulas [This is the step I have problem with]
Copy the formula results values to the 2nd excel file [This part is working but as formula is not calculated the values are not being copied over]
I am reluctant to use excel interlop library as closing the excel does not work as well.
I have an Excel report generation app using EPPlus. In one of sheets the formulas are getting dynamically updated, formulas referencing other sheets data. When I open the generated report I am able to see the formulas but the data is getting reflected only when I manually save the Excel sheet.
The reference sheet was also dynamically added, but when I changed it to static sheet the issue persisted.
Do I need to call some other function to update the formulas?
ok got it.
I need to call
package.Workbook.Calculate()
I have Two Excel Files
abc.xlsx
--Summary
xyz.xlsx
--Summary
I want to give Reference of one cell from abc.xlsx excel File to xyz.xlsx file
ws.Cells[1, 4].Formula = "('[abc.xlsx]Summary'!$D$36)";
But it is not working
The issue is that Excel formulas linked to other workbooks doesn't update automatically (without opening the source) but when i open the source workbook it automatically update itself.
Can any one suggest a correct answer
I m using https://epplus.codeplex.com/
Thanks
Formulas can't update without an instance of Excel to update them. Excel files are not standalone.
I am trying to combine a directory of Excel Workbooks that have 1 worksheet each which I generated from SSRS into one workbook without losing its formats and Cell Styles and merged cells. I am trying use NPOI but I can't seem to fins anything that will keep my formatting (Each spreadsheet was generated from several sub reports into one report so the layout from SSRS is contains various merged regions). Any ideas on how I might accomplish this?
I have an automated test which produces a csv with two columns of data.
I have an excel file which I use to gather the results of all the runs in a worksheet.
I want to fully automate the process of updating the Excel file after each test run.
This is probably what I want to do:
1. Read the two columns from the CSV file
2. Paste the two columns in a worksheet in the excel file, in the first
empty column to the right of the existing block of columns.
3. Save the Excel file
EDIT:
Now i understand that i can do steps 1-3 using a macro.
All that is left for me to figure out is how to launch the macro.
You can read the csv and write to the Excel sheet with a single data provider, the OleDb provider. Here is an article on how to write to Excel, and here is one on how to read csv.
Once you write the macro, it should be in the macro list in Excel for that Excel document. You can bind the macro to a keystroke (like Alt-i, Alt-whatever) so that it runs when your press that key combination.
I've done this on a couple of similar projects where I need to import CSV files from other sources and put the data into an Excel sheet (or sheets)
