CSV 统计分析器

常见问题

Quick answers.

›What statistical measures are included?

The tool calculates count, sum, mean, median, mode, variance, standard deviation, and the five-number summary (min, Q1, median, Q3, max).

›Does my CSV file leave my computer?

No. The analyzer uses the File API to read your document directly in the browser; the data is processed in memory and never transmitted to our servers.

›How does it handle non-numeric values?

It identifies columns containing numbers and ignores any cells with text or symbols. If a column is entirely non-numeric, it is excluded from the statistical summary.

›Is there a file size limit?

The limit depends on your browser's available memory. Most modern browsers can handle CSV files up to several hundred megabytes without difficulty.
