Introdu\u00e7\u00e3o ao Uso do ESQUERDA no Excel e Google Planilhas<\/h2>\n

A fun\u00e7\u00e3o ESQUERDA \u00e9 extremamente \u00fatil no Microsoft Excel e no Google Planilhas para extrair uma quantidade espec\u00edfica de caracteres a partir do in\u00edcio de uma string. Essa fun\u00e7\u00e3o \u00e9 amplamente utilizada em diversos contextos, incluindo an\u00e1lises de dados, limpeza de informa\u00e7\u00f5es e elabora\u00e7\u00e3o de relat\u00f3rios.<\/p>\n

Sintaxe e Exemplos B\u00e1sicos<\/h2>\n

A sintaxe da fun\u00e7\u00e3o ESQUERDA \u00e9 simples:<\/p>\n

=ESQUERDA(texto; [n\u00famero_de_caracteres])<\/code><\/pre>\n
Onde:<\/p>\n
    \n
  • texto<\/strong> \u00e9 a string da qual voc\u00ea deseja extrair os caracteres.<\/li>\n
  • n\u00famero_de_caracteres<\/strong> \u00e9 um argumento opcional que especifica o n\u00famero de caracteres a serem extra\u00eddos do in\u00edcio do texto. Se omitido, o padr\u00e3o ser\u00e1 1.<\/li>\n<\/ul>\n
    Exemplo 1:<\/strong> Considere que voc\u00ea tenha a string ‘TutorialExcel’ na c\u00e9lula A1. Para extrair os primeiros 8 caracteres, voc\u00ea aplicaria a f\u00f3rmula:<\/p>\n
    =ESQUERDA(A1; 8)<\/code><\/pre>\n
    Isso resultaria em ‘Tutorial’.<\/p>\n
    Aplica\u00e7\u00f5es Pr\u00e1ticas<\/h2>\n
    Extra\u00e7\u00e3o de C\u00f3digos de Produtos<\/h2>\n
    Digamos que em uma lista de c\u00f3digos de produtos, os tr\u00eas primeiros caracteres representam a categoria do produto, como em ‘ABC1234’, onde ‘ABC’ indica a categoria.<\/p>\n
    Solu\u00e7\u00e3o:<\/strong> Para isolar a categoria de cada c\u00f3digo na coluna A, voc\u00ea usaria:<\/p>\n
    =ESQUERDA(A2; 3)<\/code><\/pre>\n
    Assumindo que a coluna A contenha:<\/p>\n\n\n\n\n\n
    A1<\/td>\nC\u00f3digo<\/td>\n<\/tr>\n
    A2<\/td>\nABC1234<\/td>\n<\/tr>\n
    A3<\/td>\nXYZ5678<\/td>\n<\/tr>\n
    A4<\/td>\nRST9012<\/td>\n<\/tr>\n<\/table>\n
    Aplicando a f\u00f3rmula na coluna B, as categorias apareceriam isoladas em uma nova coluna:<\/p>\n\n\n\n\n\n
    B1<\/td>\nCategoria<\/td>\n<\/tr>\n
    B2<\/td>\nABC<\/td>\n<\/tr>\n
    B3<\/td>\nXYZ<\/td>\n<\/tr>\n
    B4<\/td>\nRST<\/td>\n<\/tr>\n<\/table>\n
    An\u00e1lise de Dados de Registro Temporal<\/h2>\n
    Em registros de log que cont\u00eam data e hora no formato ‘AAAA-MM-DD HH:MM:SS’, frequentemente \u00e9 necess\u00e1rio separar apenas a componente da data.<\/p>\n
    Solu\u00e7\u00e3o:<\/strong> Se a data e hora estiverem na coluna A e voc\u00ea desejar extrair somente a data, utilize:<\/p>\n
    =ESQUERDA(A2; 10)<\/code><\/pre>\n
    Com a coluna A contendo:<\/p>\n\n\n\n\n
    A1<\/td>\nData e Hora<\/td>\n<\/tr>\n
    A2<\/td>\n2023-12-01 08:30:00<\/td>\n<\/tr>\n
    A3<\/td>\n2023-12-02 09:15:30<\/td>\n<\/tr>\n<\/table>\n
    A f\u00f3rmula resultaria no seguinte na coluna B:<\/p>\n\n\n\n\n
    B1<\/td>\nData<\/td>\n<\/tr>\n
    B2<\/td>\n2023-12-01<\/td>\n<\/tr>\n
    B3<\/td>\n2023-12-02<\/td>\n<\/tr>\n<\/table>\n
    Esses exemplos ilustram como a fun\u00e7\u00e3o ESQUERDA pode ser aplicada eficazmente em v\u00e1rias situa\u00e7\u00f5es para manipula\u00e7\u00e3o de strings e dados no Microsoft Excel e Google Planilhas.<\/p>\n","protected":false},"excerpt":{"rendered":"
