By "Excel file", do you mean a file with the extension .xls or .xlsx, a proprietary file format for Microsoft Excel, or a file with the extension .csv, a plain text file divided into "rows" and "columns" by lines of text (rows), with the lines separated into fields by commas (columns) (or, in some cases, by another "separator character -- LabVIEW uses a <tab> by default, as does Excel, which has the ability to read .csv files)?
For true Excel files, NI's Report Generation Toolkit (which may be an "extra-cost item" depending on your License) will do the trick, as will some third party addons. For .csv files, LabVIEW provides Delimited Spreadsheet functions (Read and Write) which will return a 2D array of Strings or numerics.
