Excel Data Validation Blind Spot

Macro to fix it

One of the problems with Excel’s Data Validation is that it is possible to have an invalid entry in a data validation cell. This can be caused by Paste Special Values or linked drop downs that don’t update if an earlier drop down is changed. To easily identify invalid cells you can use a macro.

Data Entry Formats in Excel [Video]

Format as you go

When you enter data into Excel you can format as you type. See how in this short video.

 

Excel Power Query and Multiple Files 2022

Webinar recording from April 12, 2022

This is the recording of the second free Power Query webinar I ran in 2022.

You can watch the first one at this link.

In this session we see how to import multiple files in one Power Query. We look at importing CSV and Excel files.

One Minute to Excel #25 – Find the breakeven point

Goal Seek solution

If we have a simple Profit and Loss and we want to figure out a breakeven point, we can use Goal Seek to find it.

We can also use it to see sales required to meet a certain profit.

All in less than in minute.

One Minute to Excel #24 – 1,000 random dates

A RANDARRAY solution

Let’s say we need to do some testing and we need 1,000 random dates in 2022.

We can use a new function to make this easy to create and easy to change.

RANDARRAY usually works with numbers but in Excel dates are numbers, so we get it to create random dates for us.

I set myself a challenge to do this in less than minute – see how I went in the video below.

Conditional Format to Display Only the First Entry

In my previous blog post I showed a technique to reduce clutter. The technique used a manual formatting method. Here is the automated version.

You can see my previous post here.

Below is the original table.

We can use a Conditional Format to only display the first entry of each date in the Date column.

Select the range A2:A11.

Click the Conditional Formatting drop down and select New Rule (third from the bottom).

Select the last option in the top section “Use a formula to …”.

In the formula box enter the following formula.

=COUNTIF($A$2:A2,A2)>1

Click the Format button and use the Font tab and change the font colour to White and click OK and then OK again.

The result is shown below.

The formula for a conditional format must return TRUE to trigger the format. The type of formula that you use is called a logical test, which returns either TRUE or FALSE.

The use of the $ signs is very important in this formula. The COUNTIF function counts the number of entries in a range. If the COUNTIF result is above 1 it is a duplicate. In cell A2 the formula will ALWAYS return 1 as it is counting itself.

When creating a formula-based condition across a range you need to build the formula to refer to the top left cell of the range. In this case we need the range to expand as the range extends down the sheet. Hence, we didn’t use any $ signs on the last two A2 references used.

In cell A3 the formula will be.

=COUNTIF($A$2:A3,A3)>1

This is because the A2 references in the original formula had no $ signs, so they will change with the cell to A3. In our case this COUNTIF will return 2 because the date in cell A3 is a duplicate of the date in A2. This will trigger the format.

This formula expands as the range extends. It uses the cell reference of the cell it is in to determine if the entry is the first entry or a duplicate. This formula will not change the format of the first entry, but it will change the formats of any duplicates.

Input Data Display Hack for Excel

Getting the format white

When creating data input sheets, it is a good idea to use a table layout. Sometimes they can end up looking a little bit busy, especially if you are repeating entries down rows. To help users focus on what they need to do, you can use a little formatting hack to make the layout look a little less cluttered.

One Minute to Excel #23 – Text numbers to real number again

Another solution

One thing you learn quickly about Excel is that there are many ways to achieve the same outcome.

This is another example. In an earlier video I showed two separate ways to convert text numbers into real numbers.

Well, I have just learned another way. An Excel MVP Rick Rothstein shared a third way.  I tweaked it and share a keyboard shortcut to do it as well.

Hope you enjoy it.

If you use Text to Columns for other conversion in the same session, you may need to use Alt A E W F as the Delimiter defaults may interfere with the conversion.

 

Pasting into a Large Formatted Table

There is a quick way to do this

There are times when pasting to the bottom of an existing large, formatted table can take a few minutes to update. There is a quicker way.

When the formatted table is selected there is a Table Design (or Design) tab visible.

On the far left-hand side the Resize Table icon allows you to easily extend the range of the formatted.

You can amend the range and add sufficient rows to handle the new data in the dialog that opens.

When you paste into an existing formatted table (rather on the end of the table) you will find it will update a lot quicker.

One Minute to Excel #3 – Filling in the blanks

No blank looks

Imported data often has missing entries you need to populate.

You can use Power Query, but that duplicates the table.

This technique works on the existing table and is quick and easy to apply once mastered.

One Minute to Excel #2 – Identify Duplicates

Short, sharp video tips

In the previous video I removed duplicates, in this video we identify duplicates using Conditional Formatting.

I identify the duplicates twice in a minute in this video.

The clock is ticking.
