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

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

‘InsertRow’ method has three overloads as below.

1. InsertRow(int index)
2. InsertRow(int rowIndex, int rowCount)
3. InsertRow(int rowIndex, int rowCount, ExcelInsertOptions insertOptions)

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

InsertRow(4, 2, ExcelInsertOptions.FormatAsBefore);
