Objectifs :

This tutorial aims to teach users how to utilize Power Automate Desktop to extract information from a website and transfer it into an Excel spreadsheet, streamlining data management and reducing manual entry tasks.

Chapitres :

  1. Introduction to Power Automate Desktop
    In this tutorial, we will learn how to use Power Automate Desktop to extract information from a website and transfer it into an Excel spreadsheet. This process will help automate data collection, making it more efficient.
  2. Creating a New Flow
    To start, create a new flow in Power Automate Desktop. Since the flow is more complex, there are no predefined templates available, so we will begin with a blank canvas. Name your flow and confirm your choice.
  3. Setting Up the Canvas
    Once in the canvas space, filter the action column on the left to list the browser actions. The first action is to open Microsoft Edge. Drag and drop this action onto the canvas and enter the URL of the desired platform, choosing to open it in expanded mode (maximized window).
  4. Opening the Excel File
    Next, move to the Excel actions to open your target file, which in this example is synchronized with OneDrive. Each action will generate one or more auto-named variables, but it is advisable to customize these variable names for easier flow maintenance and element identification.
  5. Customizing Variable Names
    For this tutorial, we will customize only a few variable names by double-clicking on them. This allows for multiple executions of the flow. Make sure to clear the content of the Excel table before injecting updated data into it.
  6. Reading Table Content
    Add an action to read the table content by retrieving data from the file and storing it in a variable named 'Excel data'. This will allow for initiating a loop to delete each row. Initialize the loop variable at two to start from the second row and set the loop end at the count of rows in the 'Excel data' variable.
  7. Deleting Rows
    For example, if your file contains 50 rows, you will need to create 49 deletion loops, preserving the header row. Add the Excel row deletion action, which will delete row two at each loop, repeating this 49 times.
  8. Extracting Web Data
    To retrieve web data, use the 'Extract data from web page' action. Once in the properties window, switch to the previously opened browser page. A Power Automate web assistant should appear when hovering over page elements, with a red box delimiting a detected area.
  9. Selecting Elements to Extract
    Right-click and select 'Extract element value' for the desired items. Repeat this action three times for the items to be retrieved, corresponding to the columns of the Excel file (trainer name and details). Power Automate will automatically detect recurring elements on the entire page, saving you from individually clicking on each block.
  10. Defining Navigation and Data Storage
    Define the navigation arrow at the bottom of the page as the page selector. Next, set the number of pages to process to capture the first five pages. The data will be stored in a variable named 'data from web page'.
  11. Writing Data to Excel
    You can now write this data into your spreadsheet, starting from cell A2 (first column, second row). Add an action to automatically resize the columns based on the data present, and finalize by closing Excel and your browser instance.
  12. Testing the Flow
    Save the flow and then test it. You will see on your screen that actions are being performed, and after a few seconds, you can verify that your Excel file is correctly populated.
  13. Customizing Page Extraction
    To have the option of choosing the number of pages to extract, initialize an input dialogue box at the beginning of the flow. Customize the title and content in the web extraction action, replacing the value for the number of pages to extract with the one entered in the dialogue box.
  14. Conclusion
    By following these steps, you can efficiently extract information from your website and transfer it into an Excel spreadsheet, saving you from numerous manual copy-paste operations. Test the flow again to ensure everything works correctly.

Neste tutorial,
00:00:03
vamos aprender a usar o power automate desktop para extrair
00:00:07
informação de um website e transferi-la para uma folha de cálculo do Excel
00:00:13
para começar a criar um novo fluxo no Power Automate Desktop.
00:00:16
Uma vez que o fluxo é mais complexo, não existem modelos predefinidos.
00:00:20
Então, vamos começar com uma tela em branco
00:00:23
nomeie o seu fluxo e confirme
00:00:27
uma vez no filtro de espaço da tela,
00:00:29
a coluna de ação à esquerda e lista as ações do navegador.
00:00:33
A primeira ação é abrir o Microsoft edge no nosso caso,
00:00:37
dragão solte a ação e insira o URL da plataforma desejada por
00:00:41
escolher abri-lo em modo expandido equivalente a uma janela maximizada.
00:00:46
Em seguida, vá para as ações do Excel para abrir o seu ficheiro de destino
00:00:52
que neste exemplo está no onedrive sincronizado.
00:00:56
Cada ação irá gerar uma ou mais variáveis com nomes automáticos.
00:01:00
Aconselha-se a personalização dos nomes das variáveis
00:01:03
para facilitar a manutenção do fluxo e a identificação dos elementos.
00:01:07
Para este tutorial,
00:01:08
personalizaremos apenas alguns nomes de variáveis clicando duas vezes neles
00:01:12
permitir múltiplas execuções do fluxo.
00:01:14
Certifique-se de limpar o conteúdo do
00:01:16
Tabela Excel antes de injetar dados atualizados nela.
00:01:20
Adicione uma ação para ler o conteúdo da tabela, recuperando dados de
00:01:24
o ficheiro e armazená-lo numa variável chamada dados do Excel.
00:01:28
Isto permitirá iniciar um loop para eliminar cada linha,
00:01:33
inicializar a variável de loop às duas para começar a partir da segunda linha
00:01:37
e defina o final do loop na contagem de linhas na variável de dados do Excel.
00:01:42
Por exemplo, se o seu ficheiro contiver 50 linhas,
00:01:45
terá de criar 49 loops de eliminação.
00:01:48
A linha de cabeçalho a ser preservada,
00:01:51
adicionar a linha do Excel,
00:01:52
acção de eliminação que irá apagar a linha dois em cada loop e fazê-lo 49 vezes.
00:01:58
Se o seu ficheiro contiver 50 linhas
00:02:02
para recuperar dados da Web, use a ação extrair dados da página da Web.
00:02:08
Uma vez na janela de propriedades, mude para a
00:02:11
página do navegador aberta anteriormente no URL da Web
00:02:14
Deve aparecer um assistente web power automatize
00:02:17
ao passar o mouse sobre os elementos da página.
00:02:19
Uma caixa vermelha delimitando uma área detectada aparecerá com a direita, clique e selecione
00:02:24
extrair o valor do elemento. Em seguida, texto
00:02:28
repita esta acção três vezes nos itens a recuperar correspondentes
00:02:32
às colunas do nome e detalhes do formador de ficheiros Excel.
00:02:39
O Power Automate detectará automaticamente elementos recorrentes na totalidade
00:02:43
página que o poupa de clicar individualmente em cada bloco.
00:02:47
Isso também é visível na pré-visualização do Power Automate.
00:02:51
Então
00:02:52
definir a seta de navegação na parte inferior da página como o seletor de página
00:02:59
em seguida, defina o número de páginas a processar para capturar as primeiras cinco páginas.
00:03:04
Os dados serão armazenados numa variável denominada data da página web.
00:03:10
Agora pode escrever estes dados na sua folha de cálculo.
00:03:17
A partir da célula A, duas primeiras colunas, segunda linha,
00:03:22
adicionar uma acção para redimensionar automaticamente as colunas com base nos dados presentes,
00:03:30
finalizado com o fecho do Excel
00:03:35
e a instância do seu navegador.
00:03:40
Salve o fluxo e teste-o.
00:03:45
Irá ver no ecrã que as acções estão a ser executadas.
00:03:50
E depois de alguns segundos, pode verificar se o seu ficheiro Excel está correctamente preenchido.
00:03:57
Para ter a opção de escolher o número de páginas a extrair,
00:04:00
inicializar uma caixa de diálogo de entrada.
00:04:02
No início do escoamento,
00:04:05
personalizar o título e o conteúdo
00:04:09
na acção de extração web,
00:04:10
substitua o valor do número de páginas para
00:04:13
extrair com o inserido na caixa de diálogo.
00:04:17
Teste o fluxo novamente para garantir que tudo funcione corretamente.
00:04:21
Seguindo estes passos,
00:04:22
pode extrair informações do seu website de forma eficiente
00:04:25
e transferi-lo para uma folha de cálculo do Excel,
00:04:28
