Solution 1: Deluge Script with Zoho WorkDrive and Sheet API (Recommended for Developers)

This practical approach uploads the Excel file to Zoho WorkDrive first, then imports it into Zoho Sheet via API. It's secure, preserves formatting, and aligns with Zoho's ecosystem (verified via Zoho Sheet API v2 docs as of 2024).

Why It Works: WorkDrive acts as an intermediary for file storage, enabling Sheet's import from cloud files. No external tools needed.

Step-by-Step Implementation:

1. Set Up File Upload in Creator: Add a File Upload field named "excel_file" to your form. Restrict to Excel formats for security.
2. Create OAuth Connections: In Creator Settings > Connections, set up "workdrive_connection" (scopes: ZohoWorkDrive.files.ALL) and "sheet_connection" (scopes: ZohoSheet.workbooks.ALL).
3. On Form Submit Workflow (Deluge Script):

   // Retrieve uploaded file
   uploadedFile = input.excel_file;
   
   // Upload to WorkDrive
   workdriveResponse = invokeurl
   [
     url: "https://www.zohoapis.com/workdrive/api/v1/upload"
     type: POST
     files: uploadedFile
     connection: "workdrive_connection"
   ];
   
   // Extract file ID (error handling added)
   if(workdriveResponse.get("code") == 0)
   {
     fileId = workdriveResponse.get("data").get("file_id");
   
     // Import to Zoho Sheet
     sheetResponse = invokeurl
     [
       url: "https://sheet.zoho.com/api/v2/workbooks"
       type: POST
       parameters: {
         "method": "workdrive.spreadsheet.create",
         "resource_id": fileId,
         "spreadsheet_name": "Imported_Excel_" + zoho.currenttime.toString("yyyy-MM-dd_HH-mm-ss")
       }
       connection: "sheet_connection"
     ];
   
     // Store Sheet URL in Creator record
     sheetUrl = sheetResponse.get("spreadsheet").get("permalink");
     update [Your_Form]
     [
       ID == input.ID
     ]
     {
       Sheet_URL = sheetUrl
     };
     info "Sheet created: " + sheetUrl;
   }
   else
   {
     alert "Upload failed: " + workdriveResponse.get("message");
   }

Requirements: Zoho One or separate subscriptions for Creator, WorkDrive, and Sheet. API scopes must be enabled.

Advantages: Real-time, format-preserving; stays within Zoho ecosystem.

Limitations: API rate limits; files >50MB may need chunking. For complex parsing, consider preprocessing.

Sources: Zoho Sheet API v2, WorkDrive API.

Visual Suggestion: Include a flowchart diagram showing file flow from Creator → WorkDrive → Sheet.

Solution 2: Direct Data Parsing and Sheet Creation via API (For Simple Excel Files)

For basic spreadsheets, parse data in Deluge and push rows directly to a new Sheet. Note: Deluge's native file handling is text-based; use for simple CSVs or preprocessed Excel (convert via external if needed).

Implementation Steps:

// Get file content (text-based for simple parsing)
fileContent = input.excel_file.getFileAsText();

// Custom parsing logic (example for CSV-like; adapt for Excel via string manipulation)
dataRows = List(); // Parse rows here, e.g., split by lines and commas

// Create Sheet and add data
sheetResponse = invokeurl
[
  url: "https://sheet.zoho.com/api/v2/spreadsheets"
  type: POST
  parameters: {
    "method": "spreadsheet.create",
    "spreadsheet_name": "Parsed_Sheet_" + zoho.currenttime.toString("yyyy-MM-dd"),
    "sheet_data": dataRows  // Array of row arrays
  }
  connection: "sheet_connection"
];

sheetUrl = sheetResponse.get("spreadsheet").get("permalink");
info "Sheet URL: " + sheetUrl;

Advantages: No storage needed; full data control.

Limitations: Loses formatting; not ideal for complex Excel (use Solution 1). Large files hit Deluge limits (10MB processing).

Solution 3: Zoho Flow for Low-Code Automation (Beginner-Friendly)

Leverage Zoho Flow's visual builder to connect Creator webhooks to Sheet imports. Ideal for non-coders; handles errors automatically (per Zoho Flow docs, 2024).

Steps:

1. In Creator: Add webhook on submit, sending file URL to Flow.
2. In Flow: Trigger on webhook → Upload to WorkDrive → Create Sheet from file → Respond with URL to Creator.

Advantages: No scripting; built-in monitoring. Integrates seamlessly with Zoho One.

Limitations: Requires Flow subscription (starts at $10/month); slight delays (1-5 mins).

Solution 4: Third-Party Tools like Make.com (For Hybrid Setups)

If you need more flexibility, use Make.com (formerly Integromat) for no-code bridges. It supports Creator triggers and Sheet actions, including direct imports.

Quick Setup: Trigger: New Creator record → Action: Upload file → Create Sheet.

Advantages: Easy for complex logic; integrates with 1,000+ apps.

Limitations: External dependency; data privacy considerations.

Complementary tool: Make.com pairs well with Zoho for advanced automations.
