Hey there! Let's work through getting that customer-specific data limit into cell E10. Based on the reference table structure you shared, here are two reliable methods using Excel formulas:

Method 1: Use XLOOKUP (Modern Excel Versions) #

This is the most straightforward and flexible option, available in Excel 365, Excel 2021, and later.

If your customer names are in column A, corresponding data limits are in column C, and the customer you're targeting for E10 is in cell D10 (adjust these references to match your actual sheet!), enter this formula in E10:

=XLOOKUP(D10, A:A, C:C, "No limit assigned")

• Breakdown of the formula:
  • D10: The customer name you want to look up
  • A:A: The column containing all customer names
  • C:C: The column holding the matching data limits
  • "No limit assigned": The message to show if no matching customer is found (customize this as needed)

Method 2: Use VLOOKUP (Older Excel Compatibility) #

If you're using an older Excel version (2019 or earlier), VLOOKUP is a reliable alternative:

=VLOOKUP(D10, A:C, 3, FALSE)

• Breakdown:
  • D10: The customer name to look up
  • A:C: The range containing both customer names and limits (make sure customer names are in the first column of this range)
  • 3: The column number within the range that holds the data limits (since C is the 3rd column in A:C)
  • FALSE: Ensures an exact match for the customer name

Pro Tips #

• Always use exact match (the FALSE in VLOOKUP, or default in XLOOKUP) to avoid incorrect results from partial matches
• Wrap the formula in IFERROR to handle cases where a customer isn't found cleanly:

  =IFERROR(XLOOKUP(D10, A:A, C:C), "Customer not found")
  

• Double-check that your customer names are unique in the lookup column—duplicates will return the first matching limit
