ExcelInsight is a free line chart maker designed for time series and trend analysis. Upload a file with a date column and one or more numeric columns and ExcelInsight will draw a smooth, multi-series line chart in seconds.
ExcelInsight detects date columns automatically (ISO strings, Excel serial dates, MM/DD/YYYY and DD/MM/YYYY) and uses them as the X axis. Plot revenue over time, daily active users, error rates, anything that changes day by day.
Add multiple numeric columns to the same line chart to compare trends side by side — for example, monthly revenue per region or daily signups by acquisition channel.
No signup, no upload to a server. Open ExcelInsight, drop your Excel or CSV file, and get a dashboard in seconds.
