  • Main pane: In the main pane, you can modify your app according to the part you've chosen in the navigation bar.
  • App preview and the settings pane: You can view and interact with your live app in the app preview and settings window.

Save, undo, and redo changes.

Choose one of the following choices from the Save drop-down menu to save your changes:

Save - Save the application.

Verify data and save it - Save the app and check the defined data.

Click Undo (right arrow to the left of the Save drop-down).

Click Redo (the right arrow next to the Save drop-down) to undo an edit you've made.

AppSheet Automation: The Essentials

You may automate frequent business procedures and document-based workflows using AppSheet automation.


AppSheet Automation has the following advantages:

  • Combines process automation with the intent-aware, no-code platform of AppSheet.
  • Provides comprehensive connection, intelligent process authoring, and runtime so users can create and operate their business processes utilizing entities.
  • Focuses on the long tail of application integration use cases, document-based workflows, and human-centric processes.
  • Allows you to use the same parts in different automation.

Key components in AppSheet Automation

The essential elements of AppSheet Automation are outlined in the table below.

Appsheet Automation

About component reusability with AppSheet Automation

With AppSheet Automation, you can construct components once and reuse them in a variety of automation to cut down on time and speed up development. You can design actions, processes, tasks, and events that can be applied to other parts.


You can use expressions in a number of locations in the app editor to modify how your app behaves and provide consumers with more sophisticated capabilities. Expressions are utilized by several AppSheet features, such as app formulae, initial values, column limitations, virtual columns, and deep connections.

The following combination of the following can be used to construct an expression:


  • Any full number (integer), real number (floating point), positive number, or negative number.
  • Double quotes should be used around dates and times. Format times as HH:MM:SS and dates as MM/DD/YYYY. "12/31/1999" and "10:15:00," for instance. Additionally, see Date and time expressions.
  • Text that is double-quoted. Wordy terms, for instance.


  • Use a column's value by including its name in square brackets in the following format: [Column]. Columns can then be used in expressions.

Build expressions using Expression Assistant

Using the Expression Assistant, construct an expression as follows:

1.Put your cursor where you wish to put new material in the text box.

2. Expand and collapse tabs as necessary for a larger viewing area on the screen.

3. Form your expression as follows:

  • Enter the expression manually, either in full or in part, in the text box.
  • View the expression and add column references and example patterns.

4. Verify the expression's correctness.

5. If you like, test the expression.

Expression types

To retrieve a value from a specified column and row, create an expression.

Expressions for column values give the value of a particular column in a row. The row itself need not be stated; it is typically implied by the expression's context.

Conditional expressions

You can address these conditional conditions in expressions in a few different ways:

  • To select one of the outcomes depending on whether the condition evaluates to TRUE or FALSE, use the IF (condition, then-expression, else-expression) statement.
  • To provide a succession of condition-value pairs that are assessed from left to right until one of the conditions is true, use the formula IFS(condition1, then-expression1, condition2, then-expression2,...)
  • To select one of the outcomes based on the value of the expression, use the syntax SWITCH(expression, value1, result1, value2, result2,..., default result).

Date and time expressions

Date and time expressions create a DateTime, Date, Time, Duration, or Number value using Date or Duration values.

Current date and time functions

  • For the user's device's current DateTime, use NOW().
  • TIMENOW() for the user's device's current time.
  • TODAY() for the user's device's current Date.
  • For the current DateTime with no timezone offset, use UTCNOW()

Time component functions

  • To extract a list of Duration values from a text value, use the EXTRACTDURATIONS() function.
  • To extract a list of Time values from a text value, use the EXTRACTTIMES() function.
  • HOUR() to get the hour portion of a given Duration.
  • For the minute portion of a particular Duration, use MINUTE().
  • SECOND() for a particular Duration's second part.
  • For the Time from Date, DateTime, or Time, use TIME().
  • For the Duration's hourly count, use TOTALHOURS().
  • For a minute count in Duration, use TOTALMINUTES().
  • For a count of the Duration's seconds, use TOTALSECONDS().

Date component functions

  • For the Date from Date, DateTime, or Time, use DATE().
  • For the DateTime from Date, DateTime, or Time, use DATETIME().
  • DAY() uses a Date to determine the day of the month.
  • When calculating the end of a month, EOMONTH() takes into account leap years and various month lengths.
  • EOWEEK() uses Date or DateTime to determine the date of the final day of a week.
  • To extract a list of DateTime values from a text value, use the EXTRACTDATETIMES() function.

Dereference expressions

A dereference expression retrieves a column's value from a certain row of a different table.

Form and meaning

Dereference expressions take the following form:



Where value-column is the name of a column in the other table and ref-column is the name of the Ref column in this table.

Dereference a list

A list dereference is an operation that creates a new list of the values from dereferencing each reference in a column value of type List or EnumList with a base type of Ref.

Chained dereference expressions

A dereference can be dereferenced.

A three-level hierarchy might, for instance, include a Customer row, a child Order row, and a grandchild Order Detail row. A link to the Order row is present in the Order Detail row. A link to the Customer entry is included in the Order row.

List expressions

A list is a grouping of 0 or more items, all of the same sort of data, such as a list of names, a list of email addresses, a list of numbers, or a list of rows.

An expression that generates a list or an expression that employs one or more lists to generate a result of any type is referred to as a list expression.

Several functions accept input lists for lists:

  • ANY() returns one random list item.
  • The arithmetic average of a list of numerical values is provided by AVERAGE().
  • COUNT() - List item count.
  • Is it an item in a list? - IN()
  • INDEX() - A single component in a list.
  • List of entries shared by two lists returned by INTERSECT().
  • ISBLANK() checks to see if the list is empty.

Use lists to show and hide columns

You can conditionally reveal or hide a column from the user by using its Show. Expression. Are lists frequently used within Show? Expressions, even though the result of the Show? The expression must be a Yes/No decision.

Only users whose emails (USEREMAIL()) are included in the list of admin user emails (SELECT(...)) are displayed in the column when IN(USEREMAIL(), SELECT(Users[Email], ("Admin" = [Role])) is used.

The column is only displayed if the current view type (CONTEXT(...)) is included in the list of view types (...). IN(CONTEXT("ViewType"), "deck", "table"

Use lists to show and hide views

A view may be conditionally shown or hidden in the main menu or navigation bar by using the Show if expression. Even though lists are frequently used within Show if expressions, the result of the Show if expression must be a Yes/No decision.

Only users whose emails (USEREMAIL()) are included in the list of admin user emails (SELECT(...)) are displayed in the IN(USEREMAIL(), SELECT(Users[Email], ("Admin" = [Role])) statement.

Math expressions

Use other numerical values to calculate new numerical values.

Math operators

The math expressions listed below can make use of the standard numeric operators.


When two numeric values are separated by the plus sign (+), their sum is produced. The outcome will be a Number if both values are of the Number type; else, the outcome will be a Decimal.




The result of dividing the left value by the right value is produced when the slash character (/) is placed between two numerical values. The outcome will be a Number if both values are of the Number type; else, the outcome will be a Decimal.


8 / 2


The result of multiplying two numeric values is produced by the asterisk character (*) between them. The outcome will be a Number if both values are of the Number type; else, the outcome will be a Decimal.


(11.0 * 1)


When a single numeric number is preceded by the minus sign (-), the value is arithmetically negated: a positive value becomes a negative value and vice versa. The type of the outcome will be the same as the type of the initial value.




The right value is obtained by subtracting the left value from the right value when the minus sign (-) is used between two numerical values. The outcome will be a Number if both values are of the Number type; else, the outcome will be a Decimal.



Math functions

Math expressions within your app may make use of the following Math functions:

Absolute value: ABS()

AVERAGE(): A list of values' average

The closest higher number is CEILING().

Decimal from any value using DECIMAL()

The nearest lower number is FLOOR().

Natural log - LN()

Text expressions

A string of characters—letters, numbers, punctuation, emoji, spaces, or other—that is not recognized as another data type, expression term, or operator is referred to as a textual value.

Any expression that generates textual values or uses one or more textual values to generate values of any kind is referred to as a text expression.

Yes/No expressions

The result of a yes/no expression is either TRUE (yes) or FALSE (No). When an IF statement is required in AppSheet, these phrases are typically utilized.

Types of Yes/No operators include:

  • Comparison operators
  • Composition operators
  • Other operators

Comparison operators

By utilizing comparison operators with two expression parameters that have equivalent types, AppSheet offers comparison conditions. For this, comparing two or more parameters is necessary.

  • Equals: =
  • Not Equals: <>
  • Greater Than: >
  • Greater Than or Equals: >=
  • Less Than: <
  • Less Than or Equals: <=

Composition operators

This is an effective way to bring together many circumstances. You can compare more objects if you wrap numerous conditions with AND, OR, and NOT statements. These are used to decide what to do when something is true or untrue and depend on the conditions of several components.

  • AND: The expression's result will be TRUE (Yes) if every condition in the AND expression is true; if only one is false, the result will be FALSE (No).
  • OR: The OR expression will produce TRUE if any of the expression's requirements are met, FALSE otherwise.
  • NOT: Wrapping a condition result in NOT() yields FALSE if the condition result is true. Wrapping a condition in NOT() yields TRUE if it is FALSE.

Use column constraints

Each column description includes a type that describes the permitted values for the column as well as flags that indicate if the column is hidden, necessary for input, etc. While many programs can use this, there are situations when a more dynamic or data-driven technique is required. Column restrictions give rise to this.

When a user attempts to input or modify the value of a particular column, the behavior of that column is determined by an expression called a column constraint.

The following three column limitations determine whether input values for that column are valid:

  • Valid_If: What are acceptable values?
  • Required_If: Is an empty value acceptable?
  • Editable_If: Can it be modified at all?
