You need to insert the character code that Excel uses  which IIRC is 10  ten    EDIT  OK  here s some code  Note that I was able to confirm that the character-code used is indeed 10  by creating a cell containing   A B     and then selecting it and executing this in the VBA immediate window   Asc Mid Activecell Value 2 1    So  the code you need to insert that value into another cell in VBA would be  ActiveCell Value    quot A quot   amp  vbLf  amp   quot B quot    since vbLf is character code 10   I know you re using C  but I find it s much easier to figure out what to do if you first do it in VBA  since you can try it out  quot interactively quot  without having to compile anything  Whatever you do in C  is just replicating what you do in VBA so there s rarely any difference   Remember that the C  interop stuff is just using the same underlying COM libraries as VBA   Anyway  the C  for this would be  oCell Value    quot A nB quot    Spot the difference  -   EDIT 2  Aaaargh  I just re-read the post and saw that you re using the Aspose library  Sorry  in that case I ve no idea

Internally Excel uses U 000D U 000A  CR LF   r n  for a line break  at least in its XML representation  I also couldn t find the value directly in a cell  It was migrated to another XML file containing shared strings  Maybe cells that contain line breaks are handled differently by the file format and your library doesn t know about this
