The main reasons why DX promotion managers think their companies cannot stop using Excel are "Because employees are used to Excel" and "Because it takes time to select alternative systems and migrate data"!

i@OEC Co., Ltd. (Headquarters: Kita-ku, Okayama City; President: Norio Kusuda), which provides the no-code business app creation tool "@pocket", conducted a "Survey on the Impact of Corporate Excel Dependence on DX" targeting corporate DX promotion managers (men and women in their 20s to 50s). This survey revealed the actual usage of Excel by DX promotion managers in their companies, operational challenges, and the reasons why they cannot break free from Excel dependence. Against the backdrop of the development of generative AI technology and the spread of data-driven management, DX promotion in companies has entered a full-scale practical stage. To utilize AI technology in business, a centrally managed, high-quality data platform is essential. However, in many companies, data management using Excel, which has been heavily used for many years, is firmly established, and it is thought that the proliferation of files and fragmentation of data are acting as barriers to AI utilization. On the other hand, transitioning to systems to break away from Excel requires a great deal of money and time, so it is presumed that many companies are forced to continue their current operations while recognizing the issues. Amidst this, there is a lack of quantitative data showing the specific impact of on-site Excel dependence on DX promotion and the realities that hinder the departure from Excel. Therefore, i@OEC Co., Ltd. conducted a "Survey on the Impact of Corporate Excel Dependence on DX" targeting corporate DX promotion managers. - Approximately 90% of corporate DX promotion managers answered that they use Excel in their company's operations. - The top 3 tasks using Excel are: 1st "Creating materials such as reports and manuals", 2nd "Managing project progress and schedules", and 3rd "Aggregating and analyzing sales and expenses". - The main challenges in using Excel for business are "Data entry and aggregation take time and effort" and "Multiple files proliferate and there is no data consistency". - Approximately 70% of DX promotion managers at companies using Excel for business answered that their company's DX promotion status is "Promoting company-wide" or "Promoting in some departments or tasks". - The main impacts of business use of Excel on AI utilization, data utilization, and DX promotion are "Increase in man-hours for manual data processing and transcription" and "Occurrence of security and data governance concerns". - The main reasons why corporate DX promotion managers think their companies cannot stop using Excel for business are "Because employees are used to operating Excel" and "Because it takes time to select alternative systems and migrate data".
