Excel Formula Beautifier

⚡

TL;DR

Struggling to read and debug long, complex Excel formulas? This article introduces the 'Excel Formula Beautifier,' a simple web tool that instantly transforms your convoluted formulas into a clean, indented, and easy-to-understand format. Just paste your formula, click a button, and see the logic clearly laid out, making it much easier to analyze and troubleshoot.

Can you read =IF(AND(A1<100,B1<>"",ISNUMBER(SEARCH("abc",C1))),TEXT(D1,"dd-mm-yyyy")&" - "&ROUND(E1/F1,2),"N/A") without thinking, ok, let's take a few seconds to analyze the formula and understand what it does? On my own, no, I have to stop for a moment and take the time to read before I understand.

Years ago, for fun, I've created https://excel-formatter.avonture.be/. It joins the small family of self-hosted formatting tools I've built over time, like my SQL Formatter.

Let's discover it.

How to use

A picture is worth a thousand words...

So simply copy/paste your long formula in the first text area and click on the Beautify button.

Information

The script will try to find if the used separator is , or ; and, in case of trouble, just specify the good one.

You'll get this type of result:

=IF(
    AND(
        A1 < 100;
        B1 <> "";
        ISNUMBER(
            SEARCH(
                "abc";
                C1
            )
        )
    );
    TEXT(
        D1;
        "dd-mm-yyyy"
    ) & " - " &
    ROUND(
        E1 / F1;
        2
    );
    "N/A"
)

Which makes things clearer, no? If not, here this the transcript:

If:

A1 is less than 100,
B1 is not empty and
C1 contains abc,

Then:

D1 will be formatted as an european date and appends a rounded ratio of E1/F1.

Else:

Returns N/A.
