Survey Tabulator
Paste survey-response CSV and get a frequency table for every question, or a two-way crosstab with percentages and a chi-square test. Runs in your browser; nothing is uploaded.
About this tool
Survey Tabulator turns raw survey-response data into the two tables analysts reach for first: a frequency table (how many people picked each answer, and what percent) for every question, and a cross-tabulation that breaks one question down by another — with row, column, or total percentages and an optional chi-square test of independence (with degrees of freedom, Cramér's V effect size, and a p-value) to gauge whether two questions are associated.
Paste a CSV whose first row is the question headers and each later row is one respondent's answers. Everything runs locally in your browser — no upload, no account, no sending your respondents' data to a server.
Worked example
Given this response CSV:
gender,satisfaction,region
F,High,North
M,Low,South
F,High,North
F,Medium,North
M,High,South
M,Low,South
F,,North
Overview of the satisfaction column (blank answers dropped) reports 6
responses, 1 blank, and three distinct values — High 3 (50.0%), Low 2
(33.3%), Medium 1 (16.7%). Switch to crosstab with question gender by
satisfaction and turn on stats to get a contingency table plus a line like
Chi-square = …, df = 2, Cramér's V = …, p = ….
Options
- Mode —
overview(per-question frequencies) orcrosstab(two-way table). - Question / By — pick columns by 1-based index or header name. In overview, leave Question blank to tabulate every column.
- Crosstab percentages — show each cell as a percent of the grand total, its row, its column, or counts only.
- Include blank answers — count empty cells as a
(blank)category instead of dropping them. - Chi-square stats — append the association test to a crosstab.
- Sort — order categories by count (descending) or label (alphabetical).
- Top N — in overview, keep only the N most frequent categories per question.
- Delimiter — comma, tab, semicolon, or pipe.
Limits
- Input is parsed as text in memory; very large exports (hundreds of thousands of rows) may be slow but are not artificially capped.
- The chi-square p-value is the asymptotic upper-tail probability and, like any chi-square test, is unreliable when expected cell counts are small (a common rule of thumb is expected counts ≥ 5).
- Cross-tabs are two-way only (one row variable against one column variable).
FAQ
What format does the input need to be in?
A delimited table where the first row holds the question/column headers and
every following row is one respondent. Comma-separated is the default; set the
Delimiter option to tab, semicolon, or pipe (or paste a single custom
character) for other exports. Fields may be quoted the usual CSV way.
How do I reference a column — by name or by number?
Either. Type the exact header text (e.g. satisfaction) or a 1-based index
(2 for the second column). Indexing from 1 matches how spreadsheets label
columns, so the first column is 1, not 0.
What is a cross-tabulation and when should I use one?
A crosstab (contingency table) counts how many respondents fall into each combination of two questions — for example gender against satisfaction. It's the standard way to see whether answers to one question differ across the groups defined by another. Each cell can be shown as a percent of the row, the column, the grand total, or as a raw count.
What do the chi-square, degrees of freedom, Cramér's V and p-value mean?
The chi-square statistic measures how far the observed cell counts are from
what you'd expect if the two questions were independent; degrees of freedom
is (rows − 1) × (columns − 1). The p-value is the probability of a
chi-square that large under independence — small values (say < 0.05) suggest the
questions are associated. Cramér's V rescales chi-square to 0–1 so you can
judge the strength of that association regardless of table size.
How are blank answers handled?
By default empty cells are excluded, so percentages are out of the people who
actually answered. Turn on Include blank answers to keep them as an explicit
(blank) category and count them in the totals.
Is my survey data uploaded anywhere?
No. The tabulation runs entirely in your browser via WebAssembly — the CSV you paste never leaves your device, so it's safe for confidential or personal responses.
