Olink software excel files with the extension "xls" or "xlsx" are imported in R by the function read_npx_excel.

Olink software delimited files with suffix "csv" or "txt" are imported in R by the functions read_npx_delim or read_npx_csv.

• Files in long format are read with the column row as column names.

• Files in wide format are read with column names as V1, V2, etc.

This function also extracts the first read_n rows of the dataset to determine the Olink platform that generated the file, the data type and and file format.
