# About the Project.Json File
> `Project.json` is an automatically generated file which is created for each `.xaml` file marked as **Main** in the project folder.
`Project.json` is an automatically generated file which is created for each `.xaml` file marked as **Main** in the project folder.
The file holds varied information, including project dependencies, or web services loaded in libraries. For more information about web services in libraries, check out the [Loading Web Services in Libraries](loading-web-services-in-libraries.md) page.
:::note
**Manually editing the `project.json` file should be attempted for troubleshooting scenarios only, as it may lead to severe consequences and loss of support**.
As of 2018.2, you should specify a `project.json` file when running your project from the UiRobot.exe (command line) client.
:::
The parameters contained in the `Project.json` file are described in the following table.
Parameter
Description
name
The title of the automation project. It is provided in Studio
when creating a new process or library.
description
The description of the project. It is provided in the Description
field in Studio when a new project is created.
main
The entry point of the automation project. It consists of an
.xaml file. The default name is “Main.xaml”. It is displayed both
as the title of the Designer panel and in the Properties panel in
Studio. If you want to execute a different project first, change the value of this
parameter to the name of the .xaml file to be processed.
If your automation
project contains multiple files, each of them should be linked to the
Main.xaml file through the Invoke Workflow File
activity. This is especially useful when the project is published to Orchestrator
and sent to a Robot, as the Robot executes only the file provided in this
parameter.
dependencies
The activities packages used to create the automation project and
their versions. The list is updated every time a dependency is added or removed from
the project, or when a package version changes.
Version numbers are
composed of the following parts, in order: major, minor, build, and revision. The
build value is the number of days that elapsed since 01.01.2000. The revision value
is the number of seconds which elapsed on the day of the release, starting from 5
AM, GMT.
webServices
namespace - The
name of the service provided in the Add new service window for
libraries.
serviceDocument

metadata for the SOAP or Swagger service. The file is used when the service is
repaired, and should be versioned as part of the project.
webDocumentUri -
The file path or link to the Swagger or SOAP resource (provided when the service
is created in the Add new service window).
uniqueReference
- A reference needed for versioning the service.
entitiesStores
serviceDocument
- The path to the local entities file.
tenantName - The
tenant where the Data Service resides.
namespace - The
namespace under which the entities are imported (the project namespace).
uniqueReference
- A reference needed for versioning the service.
schemaVersion
The version of the project.json
file.
studioVersion
The version of Studio used to create the automation
project.
projectVersion
The version used when publishing this project to a feed.
Represents the one set in the Publish window.
runtimeOptions
exceptionHandlerWorkflow - The runtime exception handler for

netFrameworkLazyLoading - The option to load referenced
assemblies only if they are used in the project.
isPausable -
Whether pause is enabled for the process
isAttended -
Whether the process allows unattended executions.
requiresUserInteraction - Whether the process is a background
process.
supportsPersistence - Whether the process is a long running
process.
excludedLoggedData - Contains keywords that can be added to
the name of an activity to prevent variable and argument values from being logged
at the Verbose level. That can also be achieved by selecting the Private checkbox
of any activity. Read more about the protection of sensitive information here.
executionType -
The process execution type.
readyForPiP -
Whether the process is marked as PiP ready.
startsInPiP -
Whether the process is configured to start in PiP.
mustRestoreAllDependencies - Whether all project dependencies
are restored.
pipType - The
type of PiP used in the process.
designOptions
projectProfile -
The Studio profile used when the project was created, either Business
(StudioX) or Development.
outputType Shows
the project type, either Process, Library, or Tests.
libraryOptions
includeOriginalXaml - Whether to include original workflow
files in the resulting .nupkg file.
privateWorkflows
- The full name of private .xaml files contained in the
library.
processOptions
ignoredFiles -
List of RPA workflow files ignored from publishing.
fileInfoCollection - Contains the following information for
each test case file in the process: editingStatus
(Publishable or InProgress), testCaseId, and
fileName.
modernBehavior -
Whether the process is configured to use the Modern Design Experience.
arguments
Contains the following information for each
input and output argument defined in the
workflow file that is set as Main: name, type,
whether it is required, and whether it has a default value
(hasDefault).
Arguments information is
added only to the file in the .nupkg package after
publishing.
expressionLanguage
The language set for the process (VisualBasic or
CSharp).
entryPoints
Contains the following information for each file marked as an
entry point to the process
filePath,
uniqueId. and the following
information for each input and output argument in
the file: name, type, whether it is
required, and whether it has a default value
(hasDefault).
Arguments information is
added only to the file in the .nupkg package after
publishing.
isTemplate
Whether the project is a template.
templateProjectData
Contains the following information for template projects:
defaultProjectDescription - The default project description
for processes based on the template.
defaultProjectName - The default project name for processes
based on the template.
targetFramework
