    Eelvaade

    Import-ready CSV

    Find short rows, extra columns and header mismatches before sending a file to a CRM, database import or spreadsheet workflow.

    Delimiter checks

    Auto-detect comma, semicolon, tab and pipe data, then flag files that appear to be opened with the wrong separator.

    Header validation

    Compare the first row with an expected header list and detect duplicate column names that can break downstream imports.
