How to use Lookup formula in Data Validation?
What i want to do sounds simple but I haven't found a solution.
If name/type is "cable" I want a dropdown list for "att" allowing only code1 values.
If name/type is "htrc" I want a dropdown list for "att" allowing only code2 values.
What I've tried is:
- defining a named range called "codes" for $A:$A on sheet1
- data validation for B2 on sheet2 and used formula: =IF($A2="cable";INDIRECT(codes="code1");INDIRECT(codes="code2"))
When I'm entering that I'm getting a message saying "The Source currently evaluates to an error. Do you want to continue?" and the dropdown is blank…
How to apply
We create the drop down list and we use the “OFFSET”, “MATCH”, “VLOOKUP” and “COUNTIF” in data validation.
Data validation tool restricts the user to input data to ensure its accuracy and consistency in Excel. It helps in the consistency of the data. It guides the user to input the type of option which is necessary for your worksheet. Here the problem is, we need to check the cell, if it has punctuation or not. If the cell has any punctuation mark, that value must be rejected by Excel. If you want to learn more about Data validation in Excel, follow the link. Here we will just consider the problem, allow values only with no punctuation.
How to solve the problem?
Here we have a task that only allows entries with no punctuation. So we need to focus on a list of punctuation to check.
The use of functions and a tool will help us get through the problem.
The formula be used in Data Validation tool. The formula checks the condition and returns True or False. Here the True means that the punctuation doesn't exist, so the tool accepts the value.
All of these might be confusing to understand. So, let's test this formula via running it on the example shown below. Here we will apply data validation on the cell to restrict the user to input any value which has punctuation. So below is the formula to use in the data validation tool.
Use the formula:
$ : freezes reference
$E$4:$E$10 : array of all punctuation
C4 : cell to check
Here we have punctuation in the E4:E10 array and to check is C4 cell. Now here the formula is used for the C4 cell. Copy the formula to other remaining cells using the shortcut Ctrl + D. Now we will input values in the cell to check.
Now we use the value with punctuation.
As you can see the value is not accepted by Excel and throws an error "This value doesn't match the data validation restrictions defined for this cell". You can also customize the error message and alert message to let users know what values are prohibited. Edit values as shown below.
As you can see, there is a caution sign saying "No punctuation". Now edit the error message.
As you can see, you get the caution and alert message as required. This Error alert message will be shown whenever a punctuation value is used. Now fill your database without hesitation.
As you can see here are all the values without punctuation.
Here are all the observational notes regarding using the formula.
