Question differences between app and web
While the table above describes what question types are available across Survey123 Connect, the Survey123 field app, the Survey123 web designer, and the Survey123 web app, there are differences in their behavior and implementation across platforms.
- The web designer combines integer and decimal questions into a single question type named Number. A check box in the properties of the question allows the survey designer to define which input is required.
- The email question types provided in Survey123 Connect and the Survey123 web designer are implemented differently. The implementation in Survey123 Connect automatically populates with the email address of the organizational account the user is signed in to. The implementation in the Survey123 web designer is instead a text field that only accepts formatting matching an email address.
- Geopoint, geotrace, and geoshape questions have been combined into a single question type named Map. A check box in the properties of the question allows the survey designer to define which input is required. An additional question type named Address allows for submitting geocoded points.
- Audio questions don't allow upload in the Survey123 field app as they do in the web app. To allow upload of audio in the field app, use a File question.
- Several appearances available in Survey123 Connect are instead available as separate question types in the Survey123 web designer. This includes Multiline Text, Dropdown, and Likert Scale.
- For each question, the web designer provides an option to cache the answer. In the web app, after submitting a survey record, the answer to the question will be cached in the browser and preloaded into the next submission made for this survey on that device. Caching an answer can be set for all question types except Image, File Upload, and Signature.
Survey worksheet columns
The following table contains all columns supported by Survey123. These columns are available on the survey worksheet in the Advanced template.
Column | Description |
---|---|
Select a question type from the provided list. Enter a valid list name if using a select_one or select_multiple question. | |
The field name in the feature layer. | |
The question label displayed in your survey. | |
Information that can help to answer the survey question. | |
Additional information, only displayed after pressing an icon. | |
Select the appearance of this field in your survey. | |
Select yes to require a value in this field before completing the survey. | |
When a required field has no response, the message in this column will appear to prompt for an answer. | |
Select yes to set the values in this field to read-only. These values cannot be edited in the survey. | |
Set the default value for this field. This will prepopulate the survey with the default value. This can be used to save time by either supplying a commonly used answer or showing the type of answer choice that is expected. | |
Perform calculations using the values of preceding questions (for example, ${number} * 100). Reference the calculate field to display the result (for example, The answer is ${calc}). | |
Limit the range of numbers that can be entered (for example, .>0 and .<100). It can be used with all question types. | |
When constraint conditions are not met, this message will appear to prompt a valid answer. | |
This allows you to skip questions or make additional questions appear based on the response to a previous question. A question is made visible by meeting the conditions in the relevant column (for example, ${name} = 'value'). A question hidden by this column submits only null values. | |
When using cascading selects, this field holds the expression to match the additional attribute columns on the choices tab (for example, attribute = ${value}). | |
This value specifies the number of records available in a repeat. Once the repeat count has been specified, records cannot be added to or deleted from the repeat. | |
Copy an audio file to the media subfolder for your project and type the name of your audio file (for example, audio.mp3) to present audio with your question. | |
Copy an image file to the media subfolder for your project and type the name of your image file (for example, image.jpg) to display an image with your question. | |
A field type that overwrites the default field type for the question. | |
Define the target field type in the feature layer. This can be used to overwrite the default field type (for example, calculate and select_one fields are strings by default. To save the values in the feature layer as integers, select esriFieldTypeInteger). | |
Define the target field length in the feature layer. You can use this to overwrite the default field length. | |
Provide values for the field alias in the feature layer. You can use this to overwrite the default field alias values, which are derived from the question label. | |
Provide expressions to define the style and behavior of a question (for example, the background color for groups and repeats). | |
Provide parameters for a question that are specific to Survey123 (for example, parameters to control the behavior of repeats when editing your survey). | |
Provide standard XLSForm parameters for a question (for example, the start, end, and step parameters for a range question). | |
Set file types accepted for the file question. Accepts file extensions, with multiple file extensions separated by commas (for example, .jpg, .png). | |
This allows you to skip questions or make additional questions appear based on the response to a previous question. A question is made visible by meeting the conditions in the body::esri:visible column (for example, ${name} = 'value'). A question hidden by this column still contains and submits values. | |
Provide an expression to use an input mask to provide a set format for data entry using characters and symbols. | |
Provide translations for your question labels. The language must be specified by its name and code (for example, label::Español (es)). Add a new column for each language. The list of languages will appear in a drop-down menu in the survey. | |
Provide translations for your question hints. The language must be specified by its name and code (for example, hint::Español (es)). Add a new column for each language. The list of languages will appear in a drop-down menu in the survey. | |
Provide translations for your guidance hints. You must specify the language by its name and code (for example, guidance_hint::Español (es)). Add a new column for each language. The list of languages will appear in a drop-down menu in the survey. | |
Provide translations for the message that appears if a required question is not answered. The language must be specified by its name and code (for example, required_message::Español (es)). Add a new column for each language. The list of languages will appear in a drop-down menu in the survey. | |
Provide a numeric value for the threshold (in meters) above which geopoint results will not be accepted. This only applies to geopoint questions. | |
Apply an expression that displays warnings if conditions are not met. | |
The message that displays if the bind::esri:warning conditions are not met. | |
Set to true if the app is to automatically save the response after the question. |
Appearances
You can enter the following values into the appearance column for specific types of questions to alter how they appear or behave. For more information on each, see Appearance.

Parameters
Some question types in XLSForm have additional parameters that allow you to control the style or behavior of questions in a survey. In some cases, these parameters complement the appearances that a question type supports. For an overview of the parameters supported by each question type, see XLSForm parameters.
Data validation
Entering yes as a value in the required column causes the survey question to require that the question contain a value before the form can be completed.
Default values
Entering today() into the default column of a date question sets the default value to today's date.
Responses to a select_multiple question type work differently than others, with each checked answer entered in the order it was selected, separated by commas. To define several values as defaults in a select_multiple question, separate them with commas, for example, item1,item2,item3.
Operators
The operators listed in the following table can be used in XLSForm columns that support expressions, including the constraint, calculation, and relevant columns.

<a href="https://www.esri.com" target="_blank">Link to Esri website</a>
Regular expressions
Regular expressions are sequences of characters that define a search pattern. They can be used in one question to determine its value based on other questions or to constrain data entry. A regular expression can be built from the subexpressions listed in the following table. For more information, see Formulas.
Subexpression | Match |
---|---|
^ | Matches beginning of line. |
$ | Matches end of line. |
. | Matches any single character except newline. |
[...] | Matches any single character in brackets. |
[^...] | Matches any single character not in brackets. |
\A | Beginning of entire string. |
\z | End of entire string. |
\Z | End of entire string except allowable final line terminator. |
re* | Matches 0 or more occurrences of preceding expression. |
re+ | Matches 1 or more occurrences of preceding expression. |
re? | Matches 0 or 1 occurrences of preceding expression. |
re{ n} | Matches exact number of occurrences of previous expression defined in place of n. |
re{ n,} | Matches n or more occurrences of preceding expression. |
re{ n, m} | Matches at least the number of occurrences defined by n and, at most, defined by m in preceding expression. |
a| b | Matches either a or b. |
(re) | Groups regular expressions and remembers matched text. |
(?: re) | Groups regular expressions without remembering matched text. |
\w | Matches word characters. |
\W | Matches nonword characters. |
\s | Matches a whitespace character: tab, line feed, form feed, carriage return, or space. |
\S | Matches nonwhitespace. |
\d | Matches digits. Equivalent to [0 through 9]. |
\D | Matches nondigits. |
\G | Matches point where last match finished. |
\n | Back reference to capture group number n. |
\b | Matches word boundaries when outside brackets. Matches backspace (0x08) when inside brackets. |
\B | Matches nonword boundaries. |
\n, \t, and so on | Matches new lines, carriage returns, tabs, and so on. |
\Q | Escape (quote) all characters up to \E. |
\E | Ends quoting started with \Q. |
For example, the regular expression regex(.,'^[A-Za-z]*$') requires the user to enter only letters, no numbers or special characters, into a string question.
Esri field types
