Analyze a spreadsheet or dataset in plain English
ChatGPT leads with an evidence score of 83/100, ahead of GPT for Work (8) and Julius AI (8). 5 of 5 can be used free. Best for an all-round first assistant to try: ChatGPT.
Ranked by evidence — GitHub stars, Hacker News mentions, release activity and how much you can use for free. Recomputed nightly. How the score works.
+ 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.
+ Lets you choose the model per task and run bulk prompts over whole ranges with cost estimates up front.
− Requires understanding model pricing, and large jobs can hit rate limits or time out.
+ 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.
+ Drag an AI formula down a column to classify or rewrite thousands of rows without leaving Sheets.
− Usage is credit-based and large runs get expensive and slow.
+ The AI Analyst reads your tables and suggests summaries and charts, and functions like ASK_OPENAI work right in cells.
− It is yet another spreadsheet to migrate to, and it lacks the depth of Excel for complex models.
