Quick fill of a series · البرمجة مع مارتن

The square can do more than a copy

You already know: one cell 1 dragged down → a copy of ones. Two cells 1 and 2 dragged → series 1, 2, 3, 4…

Sheets looks for a pattern. When it understands the pattern, it fills a series. When not, it copies.

💡

After dragging, in the corner a small Autofill icon. Click — it offers copy or create a series. If it fills nonsense, choose Fill series.

Numbers 1 to 10

Sheet ملاحظةs. C1 1, C2 2. Select C1:C2.
Drag the square to C10. You have 1…10.
If everywhere 1, you selected only C1. Try again with C1:C2.

Weekdays again — faster

Pocket A2 Mon, A3 Tue. Select A2:A3.
Drag to A8. Mon, Tue, Wed, Thu, Fri, Sat, Sun.
A Czech account: po, út → po…ne. Not a mistake.

Odd numbers — step 2

D1 1, D2 3. Select both. Drag to D6. 1, 3, 5, 7, 9, 11.

Months

E1 January. Drag to E4. January, February, March, April.

⚠️

A double-click on the square fills down to neighbouring data. When nothing is next to it, it fills thousands of rows. Ctrl+Z. Today rather drag with the mouse to a specific row.

Survey — numbering answers

Survey. Next to snacks in column C: C3 1, C4 2 — answer order.
Or in column A you already have text — in column D numbers 1, 2, 3 for a chart later.

🏫 Grade average

One sheet, two columns: subject and grade. At the bottom a sum and an average.

💰 Pocket money

Rows = days, columns = income / spend / left.

📊 Class survey

One question, answers in one column, later a chart.

🏆 Mini dashboard

Three numbers at the top and one chart. Numbers as a link, not copied by hand.

Now you 💪

You filled 1–10 from two pattern cells.
Seven days on Pocket without typing each day by hand (or you fixed the pattern Mon+Tue).
You tried an odd series 1, 3, 5 by dragging.
You know that one cell = a copy, two cells = a series.
After a bad drag Ctrl+Z or the Autofill menu.

✅

Check: You fill a series with the square. You do not tap days and numbers one by one.

What to take from this lesson

Two cells define the series step.
Days, months, numbers — drag instead of typing.
One cell = a copy of the same value.
Autofill fixes a bad guess.
A double-click on the square can fly off — carefully.
