Check if Excel Sheet Exists Automatically

What This Solves

• Confirm a Summary or Config tab exists before loading data.
• Skip files that already comply with your template and process only the rest.
• Protect scheduled jobs from failing when a required sheet is missing.
• Standardize workbooks as a pre-flight step for downstream automation.

How to Check if a Sheet Exists (No Scripting)

High-level Flow

1. Create a Package in Advanced ETL Processor.
2. Add a Files Loop object to target your folder and filter *.xlsx.
3. Insert the Check if Sheet Exists action and set:
   • Workbook: Current file from the Files Loop.
   • Sheet Name: e.g., Summary (case as used in your template).
4. Use the action’s True/False branches:
   • If True → continue normal processing (load data, transform, export).
   • If False → add the sheet (via Add Sheet) or move file to a _quarantine folder and notify.
5. (Recommended) Enable Execution Log for full audit trail.

Common Patterns

• Auto-Remediation: If the sheet is missing, use Add Sheet then Populate Cells with headers/formulas, and resume the main flow.
• Compliance Gate: If the sheet is missing, tag the file, move it to _review, and send a notification.
• Idempotent Updates: Check first; only add/modify when needed-safe for repeated schedules.

Why Use Advanced ETL Processor

• Self-hosted - keep sensitive data on your infrastructure.
• No scripting, no Excel - reduce maintenance and runtime fragility.
• Operational control - scheduler, logging, variables, and branching for resilient pipelines.
• Scales up - process tens of thousands of files consistently.
