ChatGPT scores 83 to Julius AI's 8 on public evidence for spreadsheets & data analysis, and they rank #1 and #3 there. Both are free to start. Numbers below are the same public signals the ranking uses, recomputed nightly — nothing here is sponsored.
ChatGPT
OpenAI's general-purpose chat assistant with web browsing, file analysis, image generation and voice.
+ The broadest feature set in one place: Deep Research, code-executing data analysis on uploaded spreadsheets, voice mode and a huge library of custom GPTs.
− Free and Plus tiers hit message caps on the best models at busy times, and answers can be confidently wrong without citations unless you ask it to search.
Julius AI
A chat-based data analyst that runs Python on uploaded spreadsheets and databases to produce charts and statistics.
+ Ask a question in plain English and get the chart, the statistical test and the code that produced it.
− Free messages are limited and it can silently misread column meanings in messy spreadsheets.
