I am able to find $cell->get_format() or $cell->format _hash in .xls files parser but not for xlsx format. I am also open to use any XLSX parser for reading the spreadsheet. Basically I am copying one spreadsheet to another preserving the format.
I am new to the Perl, Please bear up with me if it's very basic. The below code works fine copying in excel value to another. I am having trouble copying the format. I need to copy the format value from the reading file and then assign it to writing cell- self is the variable need to change.
The question I have asked Earlier
How to copy the format of the .xlsx cell using "Excel::Writer::XLSX" reader to the copied cell using "Spreadsheet::WriteExcel" writer?
And I am open to any other XLSX parser in case this is not the right to copy the format of the cell.
These modules cannot modify spreadsheets in place, so you need a reader and a writer. To read an XLSX file, use Spreadsheet::ParseXLSX which implements the same methods as Spreadsheet::ParseExcel but parses XLSX files, so its cells also have get_format which returns the properties listed here. To write a new spreadsheet use Excel::Writer::XLSX, which implements the same methods as Spreadsheet::WriteExcel but creates XLSX files. You would add formats to such a new sheet as described here.

I tried using openpyxl library to read and write data in excel. But later did I know that I need to manipulate an excel binary worksheet. openpyxl doesn't support xlsb.
Is there any other libraries that I can use to be able to read and write data in xlsb without changing any format of the excel?
The requirement is, as much as possible:
Append data at the last row (Don't rewrite the whole data as it will affect the runtime of script).
Don't convert the xlsb
Thank you in advance.
I used xlwings library. Image will be kept and I can work with .xlsb.
We are generating large XLSX documents (only data) and we have template XLSX (styles, image, etc...).
I know XLSX is just zip, you can extract them look what is inside.
It's possible somehow to copy styles & formatting from template XLSX file to generated XLSX document (copy xl/styles.xml file and zip that again is not enough). Excel complains the file is not ok, so I think there are some consistency checks?...
Thanks
We built a Python-based tool to copy XLSX styles from one sheet to another, allowing you to essentially template the visual design of a spreadsheet and apply it to new data.

I create .CSV files by building the content like this:
s= "column1, column2, column3 \r\n"
s+= "R2column1, R2column2, R2column3 \r\n"
saveas("file.csv", s);
I now need to include a way to resize the columns when viewed in Excel.
I've read that CSV cannot do this, so what is the next simplest excel file format that can? And how would new syntax look?
CSV files are simple text files that contain plain data.
You can open these files in Excel, and it will be displayed in the spreadsheet view for convenience, with each field separated by the separator (in your case the ,) in a separate cell.
Although you can change the width of an Excel column, this is purely a visual style in Excel and can only be saved in an Excel file.
The solution would therefore be to convert your CSV files to Excel (*.xlsx) files.
Depending on the language you use you can probably directly create Excel files, without the need for conversion. There are libraries available for most programming languages for exactly that purpose.

I'm processing xlsx files in PHP. When I create xlsx file using openoffice with just one filled cell, the spreadsheet already has 65536 rows itself. It looks like openoffice stores all cells even if they are empty. Is there any solution I can save only as many rows/columns as they are filled? Because every library for parsing xlsx produces then wrong number of rows so I'm not able to process it correctly. Good solution would be to achieve it directly inside openoffice, or use some external tool/script (*nix based) to clean up such xlsx file if possible.
Here is one solution:
Use OpenTBS to open the XLSX and save it with or without modifications.
OpenTBS is a pure PHP tools whose purpose is to merge data with LibreOffice and Ms Office documents using the technique of templates.
Since its version 1.9.0, OpenTBS can handle with XLSX workbooks made with LibreOffice. Such XLSX workbooks may have an extra row definition which contains a repetition attribute that extends it upon the maximum limit of row number. OpenTBS simply reduce this extra extended row into a single row.

I have to create a custom tag that uses POI to read in an excel file, modify some cells, and then write the modifications back to the same excel file. There are multiple sheets in the excel file. In some of the sheets, certain cells are locked, some cells have color coding, and some cells have drop down options. When I write the modifications back to the excel file, all these special styles must remain the same.
I noticed that I can read in an excel file as a Workbook by doing WorkbookFactory.create(). I can also read in as a HSSFWorkbook by doing new HSSFWorkbook(). My question is, which one should I use for what I want to accomplish?
Workbook is the common interface that applies for HSSF (.xls files) and XSSF (.xlsx files). By using Workbook instead of HSSFWorkbook, your code can work just the same for both file format.
From the Why Change? section on the POI website:
If you have existing HSSF usermodel code that works just fine, and you don't want to use the new OOXML XSSF support, then you probably don't need to. Your existing HSSF only code will continue to work just fine.
However, if you want to be able to work with both HSSF for your .xls files, and also XSSF for .xslx files, then you will need to make some slight tweaks to your code.
So, if you only need to support .xls, and only ever with, you can stick with HSSFWorkbook. However, if you want to work with both .xls and .xlsx, either now or in the future, use the common interfaces
