### The different data output of a variable

When you turn on the HTML view in the template the variables will appear with {the name of the data variable}. In the following examples, we will use {x, y, z} to represent data variables.

If you want to work with your data variables it is important that you know which type of output it is. In the table below you see the different data outputs in the software and what they mean.

 Output Example Explanation Text This is free text It is a regular text that can be used directly in the text Number 150 Can be used directly in the text or to make calculations Date 29-06-2022 Can be used directly in the text or calculate the time difference List Item 1, item 2, item 3 Can be used directly in the text as an enumeration or bullet points Boolean True/false Tells whether an expression is true or false

You can spot the output type on the right side of the data variable. Now that you know the different kinds of data outputs and how to spot them, let us take a look at how you can work with them in the template.

The following operators can be used in conditions and in extra variables.

### Text operators

Text operators can be used to work with data variables with text as the output.

 Operator Expression Explanation Output type Contains {x} contains 'a' Whether {x} contains the text 'a' Boolean Not contains {x} notcontains 'a' Whether {x} not contains the text 'a' Boolean Equal to {x} = 'a' Whether {x} is equal to the text 'a' Boolean Not equal to {x} != 'a' Whether {x} not equal to the text 'a' Boolean Starts with {x} startswith 'a' Whether {x} starts with the text 'a' Boolean Ends with {x} endswith 'a' Whether {x} ends with the text 'a' Boolean

You can also use another text variable instead of 'a' e.g. {x} contains {y}

### Number operators

Number operators can be used to work with data variables with a number as the output.

 Operator Expression Explanation Output Less than {x} < {y} Whether {x} is less than {y} Boolean Less or equal to {x} <= {y} Whether {x} is less than or equal to {y} Boolean Greater than {x} > {y} Whether {x} is greater than {y} Boolean Greater or equal to {x} >= {y} Whether {x} is greater than or equal to {y} Boolean Equal to {x} = {y} Whether {x} is equal to {y} Boolean Not equal to {x} != {y} Whether {x} is not equal to {y} Boolean Add {x}+{y} Adding {y} to {x} Number Substract {x}-{y} Substracting {y} from {x} Number

{y} can also be a number you write yourself e.g. {x} - 150

You can basically use all types of math operators when the data output is a number, so knock yourself out.

### Date operators

Date operators can be used to work with data variables with date or time as the output.

 Operator Expression Explanation Output Less than {x} < {y} Whether {x} is less than {y} Boolean Less or equal to {x} <= {y} Whether {x} is less than or equal to {y} Boolean Greater than {x} > {y} Whether {x} is greater than {y} Boolean Greater or equal to {x} >= {y} Whether {x} is greater than or equal to {y} Boolean Equal to {x} = {y} Whether {x} is equal to {y} Boolean Not equal to {x} != {y} Whether {x} is not equal to {y} Boolean Timespan {x}-{y} Timespan between {x} and {y} Number DaysDiff {x} daysdiff {y} Days difference between {x} and {y} Number MonthsDiff {x} monthsdiff {y} Months difference between {x} and {y} Number YearDiff {x} yeardiff {y} Year difference between {x} and {y} Number AddDays {x} adddays {z} Adds {z} days to {x} Date AddMonths {x} addmonths {z} Adds {z} months to {x} Date AddYears {x} addyears {z} Adds {z} years to {x} Date SubDays {x} subdays {z} Subtracts {z} days from {x} Date SubMonths {x} submonths {z} Subtracts {z} months from {x} Date SubYears {x} subyears {z} Subtracts {z} years from {x} Date

{y} can also be a date or time you write yourself e.g. {x} < 30-06-2022

### List operators

List operators can be used to work with data variables whit a list as the data output.

 Operator Expression Explanation Output Contains (list) {x} contains {y} Whether all elements in {y} are in the list {x} Boolean Contains (element) {x} contains {z} Whether the element {z} is in the list {x} Boolean Not contains (list) {x} notcontains {y} Whether all elements in {y} are not in the list {x} Boolean Not contains (element) {x} notcontains {z} Whether the element {z} are not in the list {x} Boolean ContainsAny {x} containsany {y} Whether any of the elements in {x} are in {y} Boolean Equal to {x}={y} Whether {x} and {y} contain the same elements (in any order) Boolean Not equal to {x}!={y} Whether {x} and {y} do not contain the exact same elements (in any order) Boolean Remove (list) {x}-{y} Remove all elements in {y} from {x} List Remove (element) {x}-{z} Remove the element {z} from {x} List Add (list) {x}+{y} Add all elements of {y} to {x} List Add (element) {x}+{z} Add the element {z} to {x} List Intersect {x} intersect {y} Intersects if all elements in {x} also is in {y} List Filter `{x} filter {{v}} contains 'a'` Filters the list to elements that contains 'a' List

The element {z} can also be a text you write yourself e.g. {x} contains 'free text'

### Other operators

Here you have a list of operators that can be used across data outputs.

 Operator Expression Explanation Output And {x} = 'a' && {x} != 'b' Whether {x} is equal to 'a' and not equal to 'b' Boolean Or {x} = 'a' || {x} != 'b' Whether {x} is equal to 'a' or not equal to 'b' Boolean Length {x:length} The length of {x} Number Substring (skip) {x:substring;c;} Skip c amount of characters in {x} Text Substring (take) {x:substring;;c} Take c amount of characters in {x} Text Substring until {x:substring_until;c;a} Take until a and skip c amount of characters in {x} Text Substring from {x:substring_from;c;a} Take from a and skip c amount of characters in {x} Text Count (list) {x:count} The number of elements in a list Number

### Create a list with bullet points

If you want to highlight some of your data you can make a list with bullet points.

 Operator Expression Example Start list
Bullet point
• {x}
• End list
• Materials: {materials}
