Layout files
Layout files are ASCII text files containing information about the structure or layout of a flat, CSV, or XML file. The layout file can have any file name and extension. ANSI encoding is not supported. Layout files containing non-ASCII characters in the field names should be saved with UTF-8 encoding.
The layout file is a delimited text file containing two to five columns. It can have a header line. Each input field in the data file is described on a separate line in the layout file. The field names, sizes, and/or types on each line must be separated by single tab or comma characters. Commas are used in the examples below.
