contract

  • input: length of the strings and number of copies
  • output: random strings as specified.
    • randomness determined by Crypto node (generate/base64)

How to run the workflow

  1. Import the workflow into your n8n project
  2. Click the Form Trigger to specify the length of the strings and how many copies to generate
  3. The workflow runs then displays the generated random strings

How to set up

  • No additional set up is necessary to execute the workflow manually.

integration Patterns of interests

  • formTrigger node to submit a form, then use form (end) node to display results at the end of the triggered workflow.
  • set(dup)-summarize(concatenate) to run a part of the workflow multiple times then merge the results to one piece of data

Generate Customizable Random Strings with Interactive Forms

This n8n workflow provides a user-friendly way to generate customizable random strings through an interactive web form. It allows users to specify parameters for the generated string, such as length and character types, and then displays the result.

What it does

  1. Triggers on Form Submission: The workflow starts when a user submits the interactive n8n form.
  2. Collects User Input: The "On form submission" node captures the user-defined parameters for string generation (e.g., desired length, inclusion of numbers, special characters, etc.).
  3. Generates Random String: The "Crypto" node is used to generate a random string based on the provided input. This node is typically configured to produce a hash or a random sequence of characters.
  4. Processes and Summarizes Output: The "Edit Fields" and "Summarize" nodes likely format and prepare the generated string for display, potentially extracting specific parts or adding context.
  5. Displays Result in Form: The "Form" node then renders an interactive form, displaying the newly generated random string back to the user. This allows for an iterative process where users can easily generate new strings with different parameters without leaving the form.

Prerequisites/Requirements

  • n8n Instance: You need a running n8n instance to import and execute this workflow.

Setup/Usage

  1. Import the workflow:
    • Download the provided JSON file.
    • In your n8n instance, go to "Workflows" and click "New".
    • Click the three-dot menu in the top right and select "Import from JSON".
    • Paste the JSON content or upload the file.
  2. Activate the workflow:
    • Ensure the workflow is active by toggling the "Active" switch in the top right corner.
  3. Access the form:
    • The "On form submission" node will provide a unique URL for the interactive form. Copy this URL and open it in your web browser.
  4. Generate strings:
    • Fill out the form with your desired string generation parameters (e.g., length, character sets).
    • Submit the form to see the generated random string displayed within the same form interface.

Two-way property repair management system with Google Sheets & Drive

This workflow automates the repair request process between tenants and building managers, keeping all updates organized in a single spreadsheet. It is composed of two coordinated workflows, as two separate triggers are required — one for new repair submissions and another for repair updates. A Unique Unit ID that corresponds to individual units is attributed to each request, and timestamps are used to coordinate repair updates with specific requests. General use cases include: Property managers who manage multiple buildings or units. Building owners looking to centralize tenant repair communication. Automation builders who want to learn multi-trigger workflow design in n8n. --- ⚙️ How It Works Workflow 1 – New Repair Requests Behind the Scenes: A tenant fills out a Google Form (“Repair Request Form”), which automatically adds a new row to a linked Google Sheet. Steps: Trigger: Google Sheets rowAdded – runs when a new form entry appears. Extract & Format: Collects all relevant form data (address, unit, urgency, contacts). Generate Unit ID: Creates a standardized identifier (e.g., BUILDING-UNIT) for tracking. Email Notification: Sends the building manager a formatted email summarizing the repair details and including a link to a Repair Update Form (which activates Workflow 2). --- Workflow 2 – Repair Updates Behind the Scenes:\ Triggered when the building manager submits a follow-up form (“Repair Update Form”). Steps: Lookup by UUID: Uses the Unit ID from Workflow 1 to find the existing row in the Google Sheet. Conditional Logic: If photos are uploaded: Saves each image to a Google Drive folder, renames files consistently, and adds URLs to the sheet. If no photos: Skips the upload step and processes textual updates only. Merge & Update: Combines new data with existing repair info in the same spreadsheet row — enabling a full repair history in one place. --- 🧩 Requirements Google Account (for Forms, Sheets, and Drive) Gmail/email node connected for sending notifications n8n credentials configured for Google API access --- ⚡ Setup Instructions (see more detail in workflow) Import both workflows into n8n, then copy one into a second workflow. Change manual trigger in workflow 2 to a n8n Form node. Connect Google credentials to all nodes. Update spreadsheet and folder IDs in the corresponding nodes. Customize email text, sender name, and form links for your organization. Test each workflow with a sample repair request and a repair update submission. --- 🛠️ Customization Ideas Add Slack or Telegram notifications for urgent repairs. Auto-create folders per building or unit for photo uploads. Generate monthly repair summaries using Google Sheets triggers. Add an AI node to create summaries/extract relevant repair data from repair request that include long submissions.
