Question: I have a report I am doing with SSRS 2008 with some rows that have multiple elements inside them. On the preview the row automatically expands to support the extra elements but however when I export the report to Excel it appears only as a single row with just the one element displayed, although all the elements are there when I double click the row or manually expand it. 

I've checked everything...Can grow is set to true and the properties on the text box allows it's height to increase however it seems to ignore these.

Here it is in the preview

In Excel

Sorry about the links to the pictures and not in this question

Answer: 
Both `CanGrow` and `CanShrink` properties should be set to `false`. There is nothing like `CanGrow` and `CanShrink` in Excel. By setting them to false it will display the height as it is. Otherwise it will set the height to a default value.

This worked for me. Check this [Row height not preserved when exporting to Excel](https://social.msdn.microsoft.com/forums/sqlserver/en-US/52722c38-a767-470f-8a12-dd3bc417d1eb/row-height-not-preserved-when-exporting-to-excel) thread for more suggestions.
I know this is an old question but I've been struggling with it. My issue was that I had a second field in a column where I inserted a placeholder underneath the field in the column. When exporting to Excel I wanted it to be tall enough that the second field would show underneath the main field in the column.

To get it to work for me, I inserted a blank column next to it and made it just wide enough for a single character. Then I click and hit enter several times to force it to be multiple lines. When I export, I have a blank column but otherwise it worked for me.
