Process starting with an Excel upload

Can you elaborate on what you mean by "register"?

When you say register to do you mean, you want to upload an excel and based on the fields in the excel specific tasks would get kicked off?

If so yes it possible but can you provide more context on the goal your trying to achieve?

The process would consist in a first step that is to upload an excel document with a header with 3 fields and under it 4 records with the header fields filled in. From that, I want to launch a task for each of the 4 records and the user has to fill in other fields based on those records. I don't know if I have explained myself better now?

By record I mean excel lines.

Hello miguelm137538 

I assume this is what you are asking? If so You can use readexcelsheetpaging excel tool plugin to read you excel file and extract values as needed. You need to write code to create tasks foreach record/row you have. You need to remove headers from parsed data or format template.

= a!localVariables(
  local!parsedFileData: index(
    readexcelsheetpaging(
      ri!excelDocument,
      0,
      a!pagingInfo(1, cons!SRT_INT_FILE_IMPORT_ROW_MAX),
      3,
      null,
      true
    ),
    "data",
    "values",
    {}
  ),
  if(
    rule!APN_isBlank(local!parsedFileData),
    {},
    a!forEach(
      items: local!parsedFileData,
      expression: a!map(
        firstName: stripwith(fv!item[1], " "),
        lastName: stripwith(fv!item[2], " "),
        allocation: fv!item[3]
      )
    )
  )
)
