This page has a freeware version of a shared file for Google Sheets which allows you to use standard Erlang-C calculations within sheets.
Note this is a beta test version that has a link to a sheet containing the functions
as scripts. Open the sheet using the link below and use File - Make a Copy to create your
own version, then edit the new copy.
The functions have the same names and parameters as the Excel versions, to view the details download the Erlang for Excel files. The functions are described in the ErlangXL.doc Word document.
