What is r1c1 in Google Sheets?
A1 notation names cells with letters for columns and numbers for rows, like C5. R1C1 notation names cells by row and column index instead. Google Sheets shows and accepts A1 style in the formula bar for almost all work.
When to use it
Use r1c1 when writing or auditing formulas that must point at the right cells after copy, fill, or sheet changes.
When to skip it
Skip worrying about r1c1 when a named range, QUERY, or pivot already expresses the logic more clearly.

I’ve been using 1-cell sheets for a while now. And I use 1 column sheets too. Or 2 column sheets. So here are the reasons I use it and can imagine you can use little, tiny, small sheets too.

A list of websites can give you two numbers at once, and neither is the number of sites on it. Pull the root domain out of each URL, count unique roots next to the row count, and match two lists on the root. A guest post by Ivan Trefilov.

Absolute reference ($)
Absolute references lock row, column, or both with dollar signs so a formula keeps pointing at the same cell when you copy it. $A$1 locks both axes. A$1 locks the row. $A1 locks the column. Mixed locks are how tax rates stay in one settings cell while a formula fills down a thousand rows.
Read guide →Open range reference
An open range reference points at an entire row, column, or unbounded slice such as B:B or 2:2 instead of a fixed rectangle like B2:B500. Formulas with open ranges include every cell in that line, which is convenient for growing tables but expensive and risky when stray values live far below your data.
Read guide →Named range
A named range gives a block of cells a readable label like Revenue or ValidStatuses instead of only B2:B500. Define names from Data > Named ranges. Formulas, charts, pivot tables, and validation rules can reference the name, which makes models easier to audit and safer when rows shift inside the named block.
Read guide →Google Sheets formulas
A formula is an instruction in a cell that calculates a result from other cells, ranges, or built-in functions. Every formula begins with =. When inputs change, the sheet recalculates so dashboards and models stay live without manual copy-paste. Formulas are the default automation layer inside the grid before Apps Script or add-ons.
Read guide →relative reference
A relative reference moves when you copy a formula because row and column offsets stay the same, not the exact cell address. Google Sheets uses A1-style addresses like B2 by default. Relative refs are the normal choice for formulas you plan to fill down or across.
Read guide →mixed reference
A mixed reference locks either the row or the column but not both, so one part of the address can change when you copy the formula. It is common in rate tables and lookups where only one direction should slide.
