Build a product code with CONCAT
Join a category prefix and an item number into a single SKU.
CONCAT
Product managers use Excel to answer their own questions quickly rather than waiting a week for someone else's queue.
Sizing an opportunity, tracking activation across cohorts, scoring a backlog, summarising feedback by theme. The bar is speed and directional accuracy rather than production-grade rigour — but the numbers still end up in a deck.
Overcomplicating. A nested formula five levels deep is harder to check than three columns that each do one thing, and in a spreadsheet others will read, legibility is a feature.
Sizing something from assumptions you state out loud, and summarising a dataset by dimension without reaching for a pivot table.
9 exercises using the situations above. Work down the levels — each one assumes the one before it.
One function, one step, a small and tidy dataset.
Join a category prefix and an item number into a single SKU.
CONCAT
Count how many rows meet a numeric condition.
COUNTIF
Work out what share of one funnel stage reached the next.
Two or three functions combined, or one function with conditions.
Return one of three labels depending on where a value falls.
IF
Apply an upper and a lower bound to the same column at once.
COUNTIFS
Read a code's prefix and translate it into a readable category name.
IFS · LEFT
Return the campaign name behind the highest conversion count.
INDEX · MATCH · MAX
Nested logic across a realistic dataset, with edge cases that bite.
Pull a fixed-length value out of the middle of a code that varies in shape.
MID · FIND
Produce a summary line combining count, total and average for one region.
COUNTIF · SUMIF
Prefer to work in real Excel? Download the practice files — the same datasets with the answer cells left blank. You lose the feedback, which is the part that does the teaching.
These are not specific to product manager — they are the keystrokes and the misconceptions that catch everyone out, whatever the spreadsheet is about.
Open a cell for editing without reaching for the mouse or the formula bar.
Copy the cell above into the cells you have selected, without dragging.
Stamp the current date into a cell as a fixed value.
Pin down what $ changes about a reference, and what it does not.
Read an error code as a diagnosis rather than a failure.
Extend a selection to the last filled row in one press.
Cycle a reference through its absolute and relative forms while editing.
Reach the paste-special dialog to drop formulas and keep results.
Identify the one situation VLOOKUP genuinely cannot handle.
VLOOKUP · XLOOKUP
Pick the right summary statistic for a set with one huge outlier.
AVERAGE · MEDIAN
Recall the argument order that differs between SUMIF and SUMIFS.
SUMIF · SUMIFS
Diagnose a match failure where both values look identical on screen.
