Properties

To refer to a different field property, use the prop("Field Name") syntax.

prop("Name")

This will return, My Entry as shown in the example above.

Constants

There are a few available constants within the formulas:

e

The base of the natural logarithm. This is also known as Eulers Number or Napier's Constant. The value is 2.718281828459045.

So when would we use something like this?

Compound Interest

pi

The ratio of a circle's circumference to its diameter.

True

The example below is what is called a ternary operator:

true ? "yes" : "no" == "yes"

Note: A ternary operator is like below (also an if expression):

condition ? value if true : value if false

False

The example below is what is called a ternary operator:

false ? "yes" : "no" == "no"

Note: A ternary operator is like below (also an if expression):

condition ? value if true : value if false

Moment.JS Date Formats

The Date functions use Moment.JS datetime formatting. Below is the reference to the supported formats.

Formatting Tokens

Year, month, and day tokens
Year, month, and day tokens
Tokens are case-sensitive.

Week year, week, and weekday tokens
Week year, week, and weekday tokens
For these, the lowercase tokens use the locale aware week start days, and the uppercase tokens use the ISO week date start days.
Tokens are case-sensitive.

Locale aware formats
Locale aware formats
Locale aware date and time formats are also available using LT LTS L LL LLL LLLL. They were added in version 2.2.1, except LTS which was added 2.8.4.
Tokens are case-sensitive.

Hour, minute, second, millisecond, and offset tokens
Hour, minute, second, millisecond, and offset tokens
Tokens are case-sensitive.

String Formats

ISO8601

An ISO 8601 string requires a date part.

2013-02-08  # A calendar date part
2013-W06-5  # A week date part
2013-039    # An ordinal date part

20130208    # Basic (short) full date
2013W065    # Basic (short) week, weekday
2013W06     # Basic (short) week only
2013050     # Basic (short) ordinal date

A time part can also be included, separated from the date part by a space or a uppercase T.

2013-02-08T09            # An hour time part separated by a T
2013-02-08 09            # An hour time part separated by a space
2013-02-08 09:30         # An hour and minute time part
2013-02-08 09:30:26      # An hour, minute, and second time part
2013-02-08 09:30:26.123  # An hour, minute, second, and millisecond time part
2013-02-08 24:00:00.000  # hour 24, minute, second, millisecond equal 0 means next day at midnight

20130208T080910,123      # Short date and time up to ms, separated by comma
20130208T080910.123      # Short date and time up to ms
20130208T080910          # Short date and time up to seconds
20130208T0809            # Short date and time up to minutes
20130208T08              # Short date and time, hours only

Any of the date parts can have a time part.

2013-02-08 09  # A calendar date part and hour time part
2013-W06-5 09  # A week date part and hour time part
2013-039 09    # An ordinal date part and hour time part

If a time part is included, an offset from UTC can also be included as +-HH:mm, +-HHmm, +-HH or Z.

2013-02-08 09+07:00            # +-HH:mm
2013-02-08 09-0100             # +-HHmm
2013-02-08 09Z                 # Z
2013-02-08 09:30:26.123+07:00  # +-HH:mm
2013-02-08 09:30:26.123+07     # +-HH

RFC 2822

Examples

Toggle Checkbox Based on Different Property

Examples

Name	Text Field	Date
Matched Value	Important	@May 23, 2019
Blank Value
Non-Matched Value	Not Important

Formula

If Text Field is empty or Text Field is equal to Important then show a checked box, else show an unchecked one.

or(empty(prop("Text Field")), prop("Text Field") == "Important")

Formula

Thank you to David Thrale for this one!

if(dateBetween(prop("Target"), now(), "days") > 0, "✅", "❌")

Logic Examples

Examples

Name	Basic If	Many Nested If

Basic If

if(true, "It's True", "It's False")

If Nesting

if(if(if(if(if(true, false, true), true, false), false, true), true, false), "It's True", "It's False")

If's will evaluate from inside out. For the above condition, it will go like so:

FALSE: if(true, false, true)
FALSE: if(if(true, false, true), true, false)
TRUE: if(if(if(true, false, true), true, false), false, true)
TRUE: if(if(if(if(true, false, true), true, false), false, true), true, false)
"It's True": if(if(if(if(if(true, false, true), true, false), false, true), true, false), "It's True", "It's False")

Example If to Count Number of Multi-Select Values

Examples

Name	People	People Count	Cost	Result
	JohnSally		1000
	John		750
	BobSallyJohn		2000

Formula

if(length(prop("People")) > 0, length(replaceAll(prop("People"), "[^,]", "")) + 1, 0)

You can also hide the People Count column and just use it as a behind the scenes calculation as well.

Assigning Point Values to Selectors

Point Values

Name	Method	Difficulty
Item 1	Fix	Easy
Item 2	Test	Medium
Item 3	Create	Hard

Method-Value

if(test(prop("Method"), "Fix"), 1, if(test(prop("Method"), "Test"), 2, if(test(prop("Method"), "Create"), 3, 0)))

Difficulty-Value

if(test(prop("Difficulty"), "Easy"), 1, if(test(prop("Difficulty"), "Medium"), 2, if(test(prop("Difficulty"), "Hard"), 3, 0)))

Point Value

prop("Method-Value") + prop("Difficulty-Value")

💡

You can go ahead and hide the Method-Value and Difficulty-Value columns then so that it cleans up the display, you can see how to do that, as below under the table menu, ...

Date Examples

Examples

Name	Origin Date	Date	Now	Month Date	Years Difference	Days Difference	Over 21 Days?	# of Week	Weekday	Midnight of Current Day
Date Tests	@Mar 01, 1985	@Mar 10, 2019

Return Number of Month

month(prop("Date")) + 1

The reason to add 1 is that this starts at 0 (January), this is then a more standard value.

Get Number of Years Between Dates

dateBetween(prop("Date"), prop("Origin Date"), "years")

Get Number of Days Between Dates

dateBetween(prop("Date"), prop("Origin Date"), "days")

Current Date & Time

now()

Is the Number of Days Between Two Dates over 21 Days

if(dateBetween(prop("Date"), prop("Now"), "days") > 21, "Yes", "No")

This is a more complex comparison that not only compares dates but also if it meets a certain criteria.

Get Number of Week

formatDate(now(), "gg")

Weekday

day(now())==0 ? "Sunday" : day(now())==1 ? "Monday" : day(now())==2 ? "Tuesday" : day(now())==3 ? "Wednesday" : day(now())==4 ? "Thursday" : day(now())==5 ? "Friday" : day(now())==6 ? "Saturday" : "Unknown"

Credit: Evgeny Petrovskiy & updates by Odysseas Lamtzidis

Midnight of Current Day

dateSubtract(dateSubtract(now(), hour(now()), "hours"), minute(now()), "minutes")

This can be useful if you need to compare dates prior to current day and additionally exclude today (now() will exclude just before current moment).

⚠️

Note on Time Value Precision Values such as Created Time, Last Modified Time and formatting dates as Unix Epoch times will only go to minute precision. Example: 1554728160000 this will not include second and fractional seconds.

Date Calculation Examples

Born	Days (inc. End Date)	Months	Years	Remaining Months	Remaining Days	Formatted Text	Name
@Nov 03, 2015

The above example was requested when very specifically formatted text was needed from a date calculation.

Formulas

Note: I am adding the +1 to include the end date in the calculation.

Days (inc. End Date): dateBetween(now(), prop("Born"), "days") + 1

Months: dateBetween(now(), prop("Born"), "months")

Years: dateBetween(now(), prop("Born"), "years")

Remaining Months: prop("Months") - 12 * prop("Years")

Remaining Days:

dateBetween(now(), dateAdd(dateAdd(prop("Born"), prop("Years"), "years"), prop("Remaining Months"), "months"), "days") + 1

Formatted Test:

concat(format(prop("Years")), " years, ", format(prop("Remaining Months")), " months, ", format(prop("Remaining Days")), " days")

Math Examples

Examples

Name	First Number	Second Number	1st # > 0 * 8 Else 0	2nd # > 0 * 8 Else 0	Round Pi Up	Round Pi Down	Round Pi to 0 Dec. Places	Round Pi to 2 Dec. Places	Round Pi to 3 Dec. Places
Number Examples	0	5							round(pi * 100) / 100

Multiply by 8 if not 0

if(prop("First Number") > 0, prop("First Number") * 8, 0)

This is just an example of a simple numerical condition

Round Pi to n Decimal Places

0 Decimals: round(pi * 1) / 1

2 Decimals: round(pi * 100) / 100

3 Decimals: round(pi * 1000) / 1000

Keep in mind that using Floor can get the same result as rounding to 0 Decimals.

Note: Default round is a single decimal place.

Round Pi Up

ceil(pi)

Note: To the nearest whole number.

Round Pi Down

floor(pi)

Note: To the nearest whole number.

Count & Contains Examples

Example

Name	People	Number of People	Check 1	Check 2	Check 3	Number Checked	Tags	Tag Has "MyTag" or "AnotherTag"
Example One	@Adam Listek		Yes		No		MyTagAnotherTagYetAnother
Example Two			Yes	Yes	Yes		YetAnother

Count Number of People in Column

if(length(prop("People")) > 0, length(replaceAll(prop("People"), "[^,]", "")) + 1, 0)

Note: Count number of comma's in the People column.

Count Number of Checkboxes Checked

toNumber(prop("Check 1")) + toNumber(prop("Check 2")) + toNumber(prop("Check 3"))

Note: Downside is you have to manually specify each Column.

Test if Tags Field Contains Values

if(or(contains(prop("Tags"), "MyTag"), contains(prop("Tags"), "AnotherTag")), "Contains Tags", "Doesn't Contain Tags")

Grade Example

Courses

Name	Grade	Weighting
Assignment 1	85	0.2
Assignment 2	85	0.4
Assignment 3		0.1
Assignment 4		0.1
Assignment 5	80	0.2

Weighted Grades

prop("Grade") * prop("Weighting")

Traditionally weighted grades are a percentage of the total which you then add up. In this case I used the Sum total at the end.

Missing Grades

(prop("Grade") > 0) ? false : true

Another idea for this is to have a related table that does the average, sum's and number of missing assignments as the total's are not usable via a formula in another page.
