Definition of External Data Validation

External Data Validation in Excel is about making sure your data input is accurate. It stops inaccuracies by giving an error message if incorrect information is entered. This helps with calculations and processing, like when a healthcare office needed to integrate geographical coordinates within medical records.

External data validation uses rules created by the user. These can be simple or complex, based on text, numbers, dates, times, regular expressions or custom formulas. Rules can be applied to multiple worksheets or workbooks in the same workbook. They can also apply to specific conditions such as ranges of values, numerical minima/maxima and character limits.

In conclusion, external data validation helps prevent users from entering incorrect or invalid data. This can stop errors and inaccuracies in calculations, as well as prevent processing errors that could lead to loss of productivity and money.

Types of External Data Validation

Let’s create a table to explain the external data validation types available in Excel.

| Type | Description |
| — | — |
| Whole Number | Validates that the entered value is a whole number between minimum and maximum values. |
| Decimal | Validates that the entered value is a decimal number between minimum and maximum values. |
| List | Validates that the entered value matches pre-defined values. |
| Date | Validates that the entered value is a valid date within limits. |
| Time | Validates that the entered value is a valid time within limits. |

External data validation can be set with messages, alerts, or formulas. Also, you can customize it to include or exclude certain parameters.
Each type is unique and customizable. Whole Number and Decimal validation types allow you to define boundaries; whereas, Lists type offers pre-defined options. Date and Time types are useful for date/time-sensitive data like deadlines and schedules.
Knowing how to use each type correctly will ensure accuracy and save time correcting errors.

Keep in mind that your external data source should always be accessible. Also, use named ranges instead of direct cell references for easier maintenance. With this setup, you can achieve more accurate and efficient record-keeping. Let’s get started!

External Data Validation with External Sources

Look no further! External data validation with Excel can be the answer to streamlining your data validation process. This section will explore the power of external data sources. You can link them to Excel and use them to validate data. We will go through three sub-sections:

  1. Linking
  2. Lookup tables
  3. Named ranges

By the end, you’ll understand how external data validation works and how it can help you.

Link external data sources for External Data Validation

Open your Excel file and select the cell where you want to perform external data validation. Go to the “Data” tab and select “Data Validation”. In the “Settings” tab, select “List” and click on the icon next to the “Source” field.

Why is External Data Validation necessary? It can use information from outside sources, like a database or another Excel file, to validate your data input. This ensures that the data is accurate and up-to-date. Automation can save time and increase accuracy too.

For example, you could use it to validate entries in an Excel spreadsheet for a retail store. The external data source could be the store’s online system. That way, you don’t have to manually cross-check with another system.

I once worked with a client who had trouble keeping their financial records accurate due to manual data entry errors. We implemented External Data Validation with links to their bank statements and accounting software. This drastically reduced inaccuracies and improved their bookkeeping process.

Now, we will discuss how to use a lookup table for External Data Validation.

Use a lookup table for External Data Validation

In Column A, insert the options for your Data Validation list. Then, in Column B, add the corresponding result for each option. Select the cells where the data validation rule should apply. Go to “Data > Data Validation“. Select “List” and type “=A2:A5” as the Source.

This lookup table allows only valid data while providing flexibility in definitions or descriptions of each option. To make this process easier, create a Named Range for the lookup table. This way, you can reference it across multiple sheets without having to retype or copy/paste the data.

Use a Named Range for External Data Validation

Do you want to use a Named Range for External Data Validation? It’s easy! Just follow these four steps:

  1. Select the cells to which you want to apply external data validation.
  2. Go to the Data tab in Excel’s ribbon and select Data Validation under the Data Tools section.
  3. In the dialog box, choose List from the Allow drop-down menu and enter your named range as the source of input values.
  4. Click OK to apply the data validation rule.

Using a Named Range makes it easier to update your list of input values without affecting dependent rules. Others who work with your Excel workbook will also find it easier to understand and maintain your data validation rules. However, you’ll need to first create and name your range in another part of your workbook or another worksheet.

Did you know you can define dynamic named ranges with an OFFSET function that takes into account the size of your current dataset? This allows the range to expand or contract automatically depending on changes in your data set.

Now you know how to use a Named Range for External Data Validation. We’ll look at troubleshooting errors and how to resolve them quickly and easily in the next section.

Check for incorrect data types in External Data Validation

External Data Validation can cause errors when data types don’t match. To avoid this, make sure to only enter numerical values in numeric fields, and no numbers or special characters (e.g. “@#$%”) in text fields.

To make data entry easier, adding a data validation message can help alert users when data is entered in the wrong format.

If errors still occur, review the data source for inconsistencies. A user once faced an issue where they couldn’t input decimal numbers, but had accidentally set the column as a whole number instead.

To troubleshoot external data validation issues further, review Excel’s documentation. Keep reading for more tips on how to avoid incorrect criteria in External Data Validation!

Check for incorrect criteria in External Data Validation

To fix external data validation errors, check the criteria in External Data Validation. If they are wrong, it’ll cause errors in your Excel spreadsheet.

Do this:

  1. Click the cell with the error.
  2. Go to the Data tab, click Data Validation.
  3. Check the criteria and make sure they’re right.

Sometimes the criteria might have been wrong or misunderstood during setup. It’s also possible that someone copied over standard criteria from somewhere else and it needs to be updated.

Figuring out wrong criteria in external data validation can be tricky. You may overlook something or miss info. But, by reviewing data validation settings and any dependent cells, you should be able to find the error quickly.

An example of when this worked was when an accountant at a finance firm had issues with stock market values being recorded wrong. After she double-checked her external data validation settings, she noticed some formatting inconsistencies in certain cells causing her formulas to be misinterpreted.

Next, we’ll go over how to check for incorrect data sources in external data validation.

Check for incorrect data source in External Data Validation

When using External Data Validation in Excel, it is important to check for incorrect data sources. This is because it can cause errors. Incorrect data sources are locations such as file paths or URLs, which might be wrong or changed without updating the validation settings.

To make sure your data source is correct:

  1. Open the worksheet with the External Data Validation rule.
  2. Select any cell with this rule.
  3. Go to the Excel ribbon and click “Data”, then select “Data Validation”.
  4. In the Data Validation dialog box, click the “Settings” tab and review the “Source” details.

If errors still occur, further troubleshooting may be needed. Common errors are “#REF!” or “#NAME?”. To prevent this, make sure the file paths or URLs are correct and match the validation settings.

Remember that changes made in external files or databases connected with the validators can also affect External Data Validation.

If multiple cells have identical validators and a change occurs in one cell, all cells with the same validators will show an error message.
