ChatGPT Integration Service (Excel Integration)
Drive Automation for Business Process Improvement
This service integrates Excel with ChatGPT to expand automation beyond traditional macro/VBA-based workflows—covering statistical processing, analysis, summarization, and visualization.
It enables easy secondary use of created data and automatically generates indicators that support critical business decisions.
Conventional Excel automation has focused mainly on repeating tasks according to predefined rules.
With this service, you can use natural language instructions to perform data cleansing, summarization, anomaly detection, and report generation—while also automatically producing statistical calculations and analytical commentary.
This allows you to standardize daily and weekly reports, integrate data across departments, and draft first-response answers for inquiries—achieving both greater efficiency and higher quality at the same time.
