When writing inside an excel file the text in the cell gets trimmed after writing.
For example:
Let's say I am trying to write : "\\r\\nThis text starts with a new line "
I would expect when I open the xlsx file for the cell to start with an empty line, but instead I get this "This text starts with a new line"
This happens only to the whitespace at the beginning and the end, which essentially gets trimmed.
I have tried setting the cell format like this but it doesn't seem to work:
new CellFormat()
{
ApplyAlignment = true,
Alignment = new Alignment
{
WrapText = new BooleanValue(false)
}
}
The problem is that the underlying format is XML. Any whitespace at the start or end of a value is ignored unless you mark the space as preserved.
To do this you need to set the Space
property to SpaceProcessingModeValues.Preserve
, for example:
Cell cell = new Cell() { CellReference = "A1" };
CellValue value = new CellValue("\r\nThis text starts with a new line");
value.Space = SpaceProcessingModeValues.Preserve;
cell.CellValue = value;
cell.DataType = new EnumValue<CellValues>(CellValues.String);
This produces XML that looks like:
<x:c r="A1" t="str">
<x:v xml:space="preserve">
This text starts with a new line</x:v>
</x:c>
The xml:space="preserve"
will prevent the whitespace from being removed from the beginning or end of the value. This produces a file that looks like the below where you can see the newline is preserved.
而不是同时添加\\r
和\\n
,请尝试仅添加\\r
