Excel 2016 - RechercheH - Formule de traitement des données - Tuto #38

Introduction

This tutorial will guide you through using the RechercheH function in Excel 2016, a powerful tool for data processing. Understanding this function can significantly enhance your data analysis capabilities, allowing you to retrieve specific information efficiently.

Step 1: Understanding the RechercheH Function

• Definition: RechercheH (or HLOOKUP) is used to search for a value in the first row of a table and return a value in the same column from a specified row.
• Syntax: The basic syntax of the function is:

  =RECHERCHEH(lookup_value, table_array, row_index_num, [range_lookup])
  

  • lookup_value: The value you want to search for.
  • table_array: The range of cells that contains the data.
  • row_index_num: The row number in the table from which to retrieve the value.
  • range_lookup: Optional; TRUE for approximate match, FALSE for exact match.

Step 2: Setting Up Your Data

• Organize your data in a horizontal format where the first row contains the identifiers you will search for.
• Ensure that your data range is clearly defined to avoid errors during lookup.

Step 3: Inserting the RechercheH Function

1. Click on the cell where you want the result to appear.
2. Begin typing the function:

   =RECHERCHEH(
   

3. Enter the arguments:
   • For lookup_value, click on the cell that contains the value you want to find.
   • For table_array, select the range of your data, including the header row.
   • For row_index_num, input the number of the row from which to return the value. This number corresponds to the row of your table, starting from the first row of the selected table range.
   • Specify FALSE for an exact match.

Step 4: Completing the Function

• After entering all the arguments, close the parentheses and press Enter.
• Your cell should now display the retrieved value based on your lookup criteria.

Step 5: Troubleshooting Common Issues

• #N/A Error: This indicates that the lookup value cannot be found. Check that the value exists in the lookup row.
• #VALUE! Error: This may occur if the row_index_num is less than 1 or greater than the number of rows in the table array.

Step 6: Practical Applications

• Use RechercheH to quickly find and analyze data from large datasets, such as financial reports or sales data.
• Consider combining it with other functions like IF or VLOOKUP for more complex data analysis tasks.

Mastering the RechercheH function in Excel 2016 can greatly improve your data processing skills. Remember to organize your data appropriately, input the function correctly, and troubleshoot common errors. With practice, you'll be able to leverage this function for effective data analysis in various real-world applications.
