Free Table 1 Generator
✓ Free ✓ No sign-up ✓ No installation ✓ Data never leaves your browser
Turn a spreadsheet into a publication-ready Table 1 of baseline characteristics in about a minute. QuickStats formats continuous variables as mean (SD) or median (IQR), categorical variables as n (%), stratifies by any grouping variable, adds p-values with the right statistical test, and copies straight into Word.
Open the Table 1 generator →How it works
- Upload a CSV, Excel, Stata, SPSS, or SAS file — or load the built-in example dataset.
- Tick the variables to include and choose a stratifying variable (e.g. treatment arm, exposure group).
- Choose options: overall column, p-values, and optional normality testing that switches non-normal variables to median (IQR) automatically.
- Copy to clipboard and paste directly into your manuscript, or download a PDF/Word report.
What the table includes
- Mean (SD) or median (IQR) for continuous variables — chosen by Shapiro-Wilk normality testing if you enable it
- n (%) for every level of categorical variables, with percentages among non-missing observations
- A Missing row per variable, so incomplete data is reported transparently
- Group columns with sample sizes, e.g. Treatment (N=150), plus an optional Overall column
- P-values from t-test / ANOVA / Wilcoxon / Kruskal-Wallis / chi-squared / Fisher's exact — selected automatically and listed in the footnote

Frequently asked questions
- What is a Table 1 in research?
- The first table of most clinical and epidemiological papers: a summary of participants' baseline characteristics, usually split by study group, with p-values comparing groups.
- Which statistical tests are used?
- t-test or ANOVA for normal continuous variables, Wilcoxon or Kruskal-Wallis for non-normal, chi-squared for categorical with Fisher's exact when expected cell counts are small. The footnote lists exactly which tests were applied.
- Can I paste the table into Word?
- Yes — one click copies formatted HTML that pastes cleanly into Word, Google Docs, or PowerPoint.
- Is my data uploaded anywhere?
- No. Analysis runs locally in your browser; a Content-Security-Policy technically prevents the page from transmitting your data.
