Analyze the data
Use Codex when you have a CSV, spreadsheet, dashboard export, Google Sheet, or local data file and want to answer a question from it. Start with the file and the question. Codex can inspect the columns, run the analysis, and create a browser visualization you can open in the Codex app.
- Attach the file or mention the connected data source.
- Ask the question you want answered.
- Have Codex inspect the columns, run the calculation, and create an HTML visualization.
- Open the local preview in the Codex browser, then continue in the same thread to adjust the chart or slice the data another way.
Use @ to attach the CSV or mention the Google Sheet. If the data came from a dashboard, export the rows first so Codex can inspect the raw columns.
Follow-up analysis
After Codex gives you the first answer, ask for the next comparison you would normally check.
You can keep going in the same thread: clean a column, exclude a test segment, compare two time windows, make the chart easier to read, or turn the result into a short note for a meeting.
