# How to fix "The file name is invalid: File names cannot contain .., ./, or .\\."

This error occurs when the name of the Excel file or compressed file (e.g., zip) you're uploading contains invalid characters like "..", "./", or ".\\".

To resolve this issue:

1. **Check Your File Name:**\
   Look at the name of the file you're trying to upload. Make sure it does not contain any of the following characters:
   * Two consecutive dots (`..`)
   * The string `./`
   * The string `.\\`
2. **Rename the File:** If your file name contains any of these invalid characters, rename the file on your computer:
   * Right-click the file and select "Rename."
   * Remove or replace any of the invalid characters listed above.
   * Ensure the new file name is simple and contains only letters, numbers, hyphens (`-`), or underscores (`_`).
3. **Upload the File Again:**\
   After renaming the file, try uploading it again.
