Automate CSV Data Processing from OneDrive to Excel
detail.loadingPreview
This n8n workflow automates the extraction, cleaning, and transfer of CSV data from new files uploaded to Microsoft OneDrive directly into an Excel spreadsheet. It intelligently processes only valid CSV files, improving data consistency and saving significant manual effort.
About This Workflow
Tired of manually downloading CSV files from OneDrive, cleaning the data, and then updating your Excel reports? This powerful n8n workflow provides a seamless automation solution. It diligently monitors a specified OneDrive folder for new file uploads. Upon detection, it first logs the event, then intelligently verifies if the uploaded file is indeed a CSV. If it's a CSV, the workflow extracts the data, applies custom cleaning logic (via a code node), prepares the fields, and finally updates a designated Excel table with the refined information. Non-CSV files are gracefully handled by stopping the workflow and signaling an error, maintaining data integrity and reducing manual intervention. Streamline your data pipelines and ensure your Excel sheets are always up-to-date with minimal effort.
Key Features
- Automated OneDrive Monitoring: Automatically triggers upon new file uploads to a watched Microsoft OneDrive folder.
- Intelligent CSV Validation: Confirms file format is CSV before processing, stopping and alerting for non-CSV files.
- Streamlined Data Extraction & Cleaning: Extracts data from CSV files and allows for custom data transformation and cleaning via a code node.
- Direct Excel Integration: Seamlessly updates specified Microsoft Excel tables with processed CSV data.
- Error Handling for Non-CSV Files: Prevents processing of incorrect file types, ensuring data quality.

Extracts data from csv): Ensure this node is correctly configured to parse your specific CSV file structure. - Customize Data Cleaning (
Cleans the output): Edit theCodenode to implement any specific data cleaning, transformation, or mapping logic required for your data. - Configure Excel Updates (
Updates the excel table): Link your Microsoft Excel credential and specify the target Excel workbook and table where the processed data should be inserted or updated. - Review
Checks if it's CSV format: Ensure the condition accurately identifies your CSV files (e.g., based on file extension or MIME type, which might need to be set in parameters). - Activate Workflow: Save and activate the workflow to start automating your data processing.
