Formatting - add comma, 2 decimal places to cell values vb.net excel interop

Question

Does anyone have any vb.net or vba code that will format excel values or a range of cells to have comma for 100s, 1000s,10000s etc.. and 2 decimal places only.

i.e. 10,256.45

Answer 1

With a reference to the range:

rng.NumberFormat = "#,##0.00"

The current selection is also a range, so if you want it to work with the selection, just use:

Selection.NumberFormat = "#,##0.00"

Answer 2

If you don't need a specific custom formatting you can use Excel styles:

allRange.Style = "Comma"; // 1234.5678 -> 1,234.56
// or
allRange.Style = "Comma [0]"; // 1234.5678 -> 1,234
