Insert new row with previous row format in Excel using C#

2 mins read

Syncfusion® Excel (XlsIO) library is a .NET Excel library used to create, read, and edit Excel documents. It also converts Excel documents to PDF files. Using this library, you can insert Excel rows with the previous row format in C# and VB.NET.

‘InsertRow’ method has three overloads as shown below:

InsertRow(int index)
InsertRow(int rowIndex, int rowCount)
InsertRow(int rowIndex, int rowCount, ExcelInsertOptions insertOptions)

These methods take input in a one-based index. In order to insert an Excel row with the previous row format, use the FormatAsBefore option in ExcelInsertOptions as shown below:

InsertRow(4, 2, ExcelInsertOptions.FormatAsBefore);

The above statement will insert two Excel rows after the 4^th row with the same formatting as in 4^th row. Similarly, if you want to inset Excel row with next row format, FormatAsAfter option can be used.
