Have you got an Excel spreadsheet (XLSX format)?
Fine!

Upload .XLSX or .XLSM file (~<100KB for free version) to make its data accessible immediately, worldwide and in very simple way!
All instructions and samples on the next page.

You don't need to use this form - you can upload the file direcly from your script (eg batch file, VBA, command line):
curl -F uploaded_file=@C:\AnyPath\YourXlsxFile.xlsx http://afin.net/ws/uploadxlsx_info.php

NOTE! Publishing data is always on your own risk!
