Here you can submit either a data file (text format) or a list of numbers. If a data file is submitted, it takes precedence over the numbers entered in the text field.
This web app can read standard numbers, e.g., 1.045, 12.4e-07, -128.3 ..., seperated by whitespace, linebreaks, commas or semicolons. It will give you a list of the numbers it has read.
