Product Help Anaconda & Miniconda

i am running code from Jupyter Notebook. I would like my program to open a file in excel. My code specifies

EXCEL_PATH = r"C:/Users/rivky/ANACONDA/strict_grammatical_3-4_word_sentences.xlsx"

THe code fails and I get the following error.

FileNotFoundError: [Errno 2] No such file or directory: 'C:/Users/rivky/ANACONDA/strict_grammatical_3-4_word_sentences.xlsx

This directory does exist on my computer. i can't figure out why python thinks the file doesn't exist. Can you help?
