This blog contains steps to copy Formatting & Style from one Excel sheet to another sheet. Also, shows how to identify the Cell Type.
To implement formatting in the excel sheet while writing data, please visit the below link:
Copy Formatting & Style

- Below are the requirements:
- inputfile.xlsx file
- Sheet having list of few Electronic items with below columns
- S.No | Numeric Data
- Item Name | String Data
- Item Code | Numeric Data
- Quantity | Numeric Data
- Formatting of Header
- Background color Tan
- Text color White
- All fields are bold
- Formatting of Item Name column
- All data is in Italic font.
- Formatting of the Quantity column
- Values less than 100 is of Red Color and in Italic font
- Other values are of Green color
- Sheet having list of few Electronic items with below columns
- inputfile.xlsx file
Code Example
- Steps to copy the data and cell style from one excel sheet to another.
- Create references for Output File
- Create references for Input File
- Navigate throughout all the cells
- Store cell data in a variable
- Identify the Cell Type like Numeric, String etc.
- Identify the Cell Style for each cell
- Copy data from an input file to Output File
- Create a new cell style with reference to the input cell
- Create a new cell type with reference to the input cell
- Write data, cell style, cell type to the output file
- Save data to the Output file.
