First time ever seeing this error message, everything was working fine last week. Any ideas…? ---

Hi @skblase, This is typically a browser-related or temporary issue. Can you try clearing cache/cookies, using a private tab or another browser entirely? Please also make sure that the file meets all requirements (supported file type, no hidden sheets, each data column has a header, no ‘rogue’ data to the right without a column header). Best regards ---
