You can use your understanding of basic spreadsheet formulas to write calculations in Coda too. You'll be able to do things you'd expect - SUM, COUNT etc., but you can also do interesting things with your data - for example, embed a Google Map based on a location description.

## Formula basics

Coda's Table formulas are different than in spreadsheets as they are at the **column level,** not at the cell level. You can trigger a column formula by clicking on a cell in a column and pressing “=”. Right-click any column and select **Add column formula** to add a column-level formula - this will apply to all rows in the table:

There are two main differences between traditional Excel formula language and Coda's language: named objects and chaining.

**Named objects**: Unlike spreadsheets where addressing was mostly done with A4 or B12 references, Coda uses the actual names of your tables and columns.

**Chaining:** With complex formulas in Excel, you’re required to *wrap *methods around “inner formulas” ー leaving you with this long block of )))))’s at the end which can be really hard to understand. So like a modern programming language, Coda supports both the traditional Function(X, Y) look from Excel as well as X.Function(Y) ー which can often help with readability.

For example, in a Table of Products, you could apply the below formulas to calculate values:

`=Products.COUNT()`

`=Products.FILTER(Quantity > 5).COUNT()`

## Formulas in the surface

One thing which makes Coda unique is the ability to add formulas anywhere - not just in Tables. If you enter the "=" sign anywhere in a document, you'll see you can write a formula - 5*5, for example.

You can also pull data in from anywhere else in the document here. For example, if you have a Table in your document, and hit "=" somewhere else, you can pull in data from that table. For example, =[Table Name].Count() will return all the rows in that table. =[To-Do List].Filter(Status="Not Started").Count() will count all the items in your To Do List which haven't been started yet. See this in action below:

You'll find you can add formulas anywhere in a Coda doc to summarize data and understand it at a glance. A best practice is to create a summary Section with a text summary of progress, and embed formulas that will automatically update based on your progress in the Tasks table, elsewhere.
