In simple terms you can do this:
a) Retrieve the file's name
b) Get the day, month and year as variables
c) Concatenate day, month and year variables into the new name you want
d) Rename the excel file.
Considering you'll download your file to a specific folder, this flow will work (actions, key parameters):
1. 'Get files in folder', Folder = where your file is. This will give you a %Files% variable
2. 'Get subtext':
- Original text = %Files[0].Name%
- Start index = Start of text
- Lenght = Num of chars
- Number of chars = 2
Rename the produced variable as %Month%
3. 'Get subtext':
- Original text = %Files[0].Name%
- Start index =Character position
- Character position = 3
- Lenght = num of chars
- Num of chars = 2
Rename the produced variable as %Day%
4. 'Get subtext':
- Original text = %Files[0].Name%
- Start index =Character position
- Character position = 6
- Lenght = num of chars
- Num of chars = 2
Rename the produced variable as %Year%
5. 'Set variable', Define = Newname, To = Report_Day_%Year%%Month%%Day%
6. 'Rename file':
- File to rename = %Files[0]%
- Rename scheme = Set new name
- New file name = %NewName%
- Keep extension = activated
