Formula Generator is an online AI formula generation tool for Excel and Google Sheets users, with its official website at https://formulagenerator.app/ . According to the official introduction, it can help users build Excel or Google Sheets documents, generate formulas, and create spreadsheets in seconds with the help of AI, emphasizing precision and efficiency.
Purpose This tool mainly serves users who need to work with spreadsheets. The official description states that the process of building Excel worksheets, complex Google Sheets spreadsheets, and formulas can be greatly simplified with the help of AI tools such as ChatGPT, thereby saving time and effort. The overall process is relatively straightforward and does not require users to have programming experience or extensive prior knowledge of spreadsheets and formulas, but the official description also notes that users need a basic understanding of spreadsheets and formulas in order to accurately describe their needs.
Main capabilities
- Instantly generate Excel and Google Sheets formulas.
- Build formulas and spreadsheet structures based on natural language descriptions.
- In addition to generation, it can also be used to explain and debug formulas, identify errors in logic, structure, or references, and provide revision suggestions.
- The official description also mentions that GPT can be trained to write automation scripts such as VBA (Excel), SQL (databases), and Apps Script (Google Sheets), for automating repetitive tasks, generating dynamic reports, and integrating with other services. The above capabilities all come from the official page description.
How to use Users can describe the desired formula in natural language (English syntax), for example explaining how the mathematical sum should be performed or how the information in each cell should participate in the calculation, and the AI engine generates a formula that is easy to review, edit, and save based on this. The official recommendation is to have some knowledge of prompt engineering to obtain more precise results through clear and specific instructions. In addition, users can set system instructions to let the AI model refer to previous prompts, thereby creating new prompts more efficiently on the same model, or building similar models without starting from scratch. The official recommendation is to treat system instructions as a project brief, clearly defining the tone, goals, typical data structures, and domain logic. The official description also mentions that the OpenAI API for ChatGPT can be connected to a front end or Google Sheets, allowing AI to directly process files or spreadsheets, and prompts such as "Act as an Excel expert" or "Review and change the sheets in the file, and please mark any edits" can be used. For advanced users, it is also possible to create dynamic templates, add validation steps or AI-generated comments, and use webhooks or automation tools such as Zapier and Make to achieve scheduled updates or real-time responses.
Applicable scenarios The applicable scenarios listed officially include: creating data analysis sheets, calculating returns or potential interest APY yields, processing large data tables, generating dynamic reports, monthly report automation (for example, using Apps Script to retrieve data from multiple worksheets, format it, and email it to relevant parties), and generating SQL queries based on natural language input for filtering, joining, or aggregating relational database data.
Limitations and notes The official description clearly states that using this tool is not zero-threshold, and users still need a basic understanding of formulas or spreadsheets; the official recommendation is that an intermediate level of understanding is sufficient. In addition, building prompts that fully meet requirements may require repeated experimentation and adjustment. Initial prompts may need correction for inconsistencies or misunderstandings, and different commands may need to be split into multiple prompts until the AI engine fully understands the requirements. Specific information such as whether the tool is completely free, whether there are paid plans, the languages supported, and platform compatibility is not provided in the official text, so it cannot be confirmed.
