Key Features and Highlights
This workflow utilizes n8n’s “Compare Datasets” node to perform comparative analysis between two datasets. It can identify and distinguish common items, differences, and unique entries within the data, supporting multiple output streams for convenient subsequent processing and in-depth analysis. The workflow is designed with simplicity in mind, enabling users to quickly understand and operate it.
Core Problem Addressed
In everyday data processing or integration scenarios, datasets from different sources or versions often contain discrepancies. Manual comparison is time-consuming, labor-intensive, and prone to errors. This workflow automates field matching and difference comparison between datasets, helping users quickly pinpoint data discrepancies and improve the efficiency and accuracy of data verification.
Application Scenarios
- Difference detection before merging multi-channel data
- Tracking data changes across different time points
- Comparison steps in data cleansing and validation processes
- Comparative analysis of business data such as supply chain, sales, and inventory
- Any business scenario requiring comparison between two structurally similar datasets
Main Workflow Steps
- Manually trigger the workflow execution
- Use two “Code” nodes named “Dataset 1” and “Dataset 2” to simulate generating two datasets containing fruit and color attributes
- Use the “Compare Datasets” node to compare the two datasets based on the fruit name field
- Output multiple data streams that differentiate identical, differing, or unique data items for easy review and further processing
Involved Systems or Services
- Built-in n8n nodes: Manual Trigger, Code (for simulated data generation), Compare Datasets, Sticky Note (for annotations)
Target Users and Value
- Data Analysts and Data Engineers: Quickly perform difference comparisons between datasets to assist in data quality checks
- Automation Developers: Use as a sample workflow to quickly get started with the “Compare Datasets” node functionality
- Business Team Members: View and understand data differences without programming, enhancing cross-department collaboration efficiency
- Education and Training: Demonstrate how to automate dataset comparison within n8n for instructional purposes
By combining intuitive node design with clear output results, this workflow helps users easily master and apply data comparison techniques, providing an effective tool for complex data processing tasks.
Import Multiple CSV Files to Google Sheets
This workflow enables the batch reading, deduplication, filtering, and date sorting of multiple CSV files, and automatically imports the processed data into Google Sheets. It supports the identification and integration of the latest subscriber data, significantly improving data processing efficiency and addressing the time-consuming and error-prone issues of traditional manual processing. It is suitable for fields such as marketing, data analysis, and content operations, helping teams stay updated on user subscription status in real-time, and supporting informed decision-making and strategy formulation.
SERPBear Analytics Template
This workflow regularly retrieves website keyword ranking data from the SERPBear platform, automatically parses it, and generates a summary of keyword performance. The data is then sent to an AI model for in-depth analysis, and the results are finally saved to a Baserow database. The purpose is to help website operators and SEO practitioners efficiently monitor changes in keyword rankings, identify well-performing and under-optimized keywords, thereby enhancing the scientific accuracy of SEO decision-making and reducing the workload of manual analysis.
LINE BOT - Google Sheets Record Receipt
This workflow automates the processing of transaction receipt images received by a LINE chatbot. By uploading the images to Google Drive and using OCR technology to recognize the information within them, the system can accurately extract transaction details and automatically record the data in Google Sheets. This process significantly enhances the efficiency and accuracy of manual data entry, addressing the challenge of structuring image information for storage. It is suitable for scenarios where efficient management of transaction receipts is needed, such as in finance departments, individuals, and small businesses.
Convert URL HTML to Markdown and Get Page Links
This workflow automatically converts webpage content from HTML format to structured Markdown and extracts all links from the webpage. Users can batch process multiple URLs, and the system will automatically manage API request rate limits to ensure efficient and stable data scraping. The workflow is flexible, supporting the reading of URLs from a user database and outputting the processing results to a specified data storage system, making it suitable for scenarios such as content analysis, market research, and website link management.
AI-Driven Automated Corporate Information Research and Data Enrichment Workflow
This workflow utilizes advanced AI language models and web data scraping technologies to automate the research and structuring of corporate information. Users can process lists of companies in bulk, accurately obtaining various key information such as company domain names, LinkedIn links, and market types. The results are automatically updated to Google Sheets for easier management and analysis. This system significantly enhances data collection efficiency, addressing issues of incomplete information and outdated updates commonly found in traditional manual research. It is suitable for scenarios such as market research, sales lead generation, and investment due diligence.
LinkedIn Profile and ICP Scoring Automation Workflow
This workflow automatically scrapes and analyzes LinkedIn profiles to extract key information and calculate ICP scores, enabling precise evaluation of sales leads and candidates. Users only need to manually initiate the workflow, and the system can automatically access LinkedIn, analyze the data, and update it to Google Sheets, achieving a closed-loop data management process. This significantly improves work efficiency, reduces manual operations, and ensures the timeliness and accuracy of information, making it suitable for various scenarios such as sales, recruitment, and market analysis.
Google Analytics Template
This workflow automates the retrieval of website traffic data from Google Analytics and conducts a two-week comparative analysis using AI, generating SEO reports and optimization suggestions. After intelligent data processing, the results are automatically saved to a Baserow database, facilitating team sharing and long-term tracking. It is suitable for website operators and digital marketing teams, enhancing work efficiency, reducing manual operations, and providing data-driven SEO optimization solutions to boost website traffic and user engagement.
Advanced Date and Time Processing Example Workflow
This workflow demonstrates how to flexibly handle date and time data, including operations such as addition and subtraction of time, formatted display, and conversion from ISO strings.
