问题
I have a list containing telephone numbers in the form "+74951234567" and I wish to export it to Excel without quotes preserving original appearance with the plus sign. In Excel I can set the cell format to "Text" and then entering +74951234567 without quotes will not result in converting it to number. Is it possible to force Export in Mathematica to create Text cells?
UPDATE
I have found an approach which allows to get what I wish: I need to export the table as XML data with formatting information added. For example, the "ss:StyleID" -> "s21" statement in XMLElement["Cell", {"ss:StyleID" -> "s21"}, {XMLElement["Data", {"ss:Type" -> "String"}, {"+74951234567"}]}] formats the cell as "Text".
I have found this by saving the table as "XML Table" from Excel and then Importing the generated file in Mathematica:
XMLData = Import["test.xml", "IncludeNamespaces" -> "Unparsed"]
The XMLData can further be modified inside Mathematica and Exported backward to XML:
Export["test-from MMa.xml", XMLData]
The exported file is opened by Excel as ordinary worksheet and can be manipulated in the usual manner.
But I still need help because I am not familiar with XML and Mathematica's XML capabilities.
UPDATE 2
It seems that another option would be using JExcelAPI Java library which I have not tried yet.
回答1:
Looks fairly simple. Use quotes in Mathematica to make Excel interpret data as text.

I don't think what you want is possible at this time, but here's how I'd go about trying it. Try creating a simple spreadsheet with what you want and Import the FormattedData element to see what the form of the data should be. Then try exporting the data back using that form.
