There are two ways to insert rows of data using ExcelWriter: ExcelTemplate's ExcelTemplate.BindData method and ExcelApplication's Worksheet.ImportData method.
ExcelTemplate.BindData
When data is imported into a template file that contains data markers with ExcelTemplate.BindData, ExcelWriter inserts a brand new row for each row of data in the data source. Content in the cells below the data markers will be pushed down as the new rows are added. Styles and formatting in the data marker row will be copied for each new row. Formulas that reference the data marker row will be updated to reflect the newly inserted rows.

Below is break down of what was affected when the data was imported.
Content below the data markers
In this example, there is content below the data marker row (a Grand Total row and a blue footer row). These will be pushed down as new rows are inserted.
...
After the data is imported, these rows are moved from rows 4 and 5 to rows 7 and 8.
Formatting on the data marker row
There are several formatting elements on the data marker row. This formatting will be applied to each new row of data.
- Currency number formatting on B3
- Italic font on B3
- Red font on C3
Before importing data
After the data is imported, this formatting is applied to rows 3 through 6.
Formulas
- There are two formulas
- B4 contains a SUM formula that references a data marker cell. The lower boundary will expand to include new rows.
- C3 contains a formula that references a data marker cell. The row values will be updated for each new row.
