File Parser control

The file parser control is a logic control that parses XML, CSV or JSON files.



UI Properties

  • Label : Label is the text that is displayed above the control and helps the user to understand the purpose of the file parser control. Visibility of Label can be toggled using the hidden property toggle option. Furthermore, size, weight, color and alignment of Label text can be altered.
  • Tooltip: This allows you to add the Tooltip text that would provide a hint to the user for providing input. The Tooltip icon would be visible if you switch on the Show tooltip icon toggle property.
  • Description: Is the description that you can add for your controls. The Description would only be visible if you switch on the visibility toggle property
    • External CSS: With this property, one can imply exclusive CSS on controls. You can customize your control with CSS by selecting the correct class or id of the control. You can read more here.
  • Grid Configurations
    Caching : When the caching option is selected and if a LOOKUP formula is applied to this control, the value that the LOOKUP returns will be cached and the user will be able to see this value in the fields even when he accesses the microapp later with no connectivity. This option is required when you want your app to be accessible in offline mode as well and getting the latest data from the sheets is not always critical.
    Hidden : The hidden option helps to hide the control from the user. This helps when you don’t want the user to view the control.
    Trigger Dependents : When you Disable Trigger Dependents, it helps you to reduce or optimize the unnecessary evaluation of the dependent control’s formula. For a detailed explanation refer to this article here ..By default Trigger dependents are enabled. However, in complex apps by switching it off, you would limit the evaluation in the dependent control and in turn ensure quicker response times.
  • Hide on desktop : This option hides the selected control in the desktop view
  • Hide on Mobile : This option hides the selected control in the mobile view.
  • Dynamic Height : This option dynamically increases /decreases the height of the text control based on the given content.
  • Maintain space when hidden : This option maintains the specified space between controls when a particular control is hidden. When a control is hidden the space is maintained in the preceding control depending on the space the previous control has occupied.
  • Maximum height : This option is used to set the maximum height of the control. Height can be in following units :- px, em , vh, %. For more information about these units, refer here.
