## Import formats

- Delimited responses (.csv, .tsv, .txt): A header row followed by response rows. UTF-8, UTF-16 and common legacy encodings (GBK/GB18030, Shift-JIS, Windows-1252) are detected.
- Excel responses (.xlsx, .xlsm): The worksheet with the most data is read, with one header row. Macros are never run.
- SPSS responses (.sav): Compressed and uncompressed SAV files keep labels, user-missing codes and ranges; date formats become calendar dates.
- JSON responses (.json, .jsonl, .ndjson): An array of flat response objects, or one object per line. Nested/repeating answers need explicit mapping.
- Qualtrics questionnaire (.qsf): Select alongside one response file. Exact export-tag matches add question wording; QSF contains no responses.
- Crosstabs project (.ctproj): A verified project containing its working dataset.
- Legacy Excel and OpenDocument spreadsheets (.xls, .xlsb, .ods, .fods): Excel 97–2003 (.xls), Excel binary (.xlsb), LibreOffice/OpenDocument (.ods) and flat OpenDocument XML (.fods) workbooks are read like .xlsx: the worksheet with the most data, with one header row. Saved formula results are used; nothing is recalculated and macros are never run.
- Other SPSS formats (.zsav, .por): Labels, user-missing codes and missing ranges are preserved; date formats become calendar dates.
- Stata (.dta): Single datasets; tagged missing values are excluded from analysis.
- SAS (.sas7bdat, .xpt): Data and embedded variable labels. External catalogs are not applied.
- R data (.rds, .rdata, .rda): Data frames, tibbles and data.tables saved with saveRDS() or save() (gzip or uncompressed). Factors keep their levels as value labels (ordered factors become ordinal); Date and POSIXct become calendar dates; haven labels, value labels and declared missing codes are kept. From an .RData file with several data frames you choose one.
- Parquet (.parquet): One table; snappy, gzip, zstd, brotli and LZ4 compression. Dates and timestamps become calendar dates, decimals become numbers and nulls become missing. Nested list, map and struct columns are imported as JSON text.
- Arrow and Feather (.arrow, .feather, .ipc): Arrow IPC files and streams and Feather version 2, uncompressed or LZ4/zstd compressed. Dictionary (categorical) columns keep their categories as value labels. Feather version 1 files must be saved again as version 2.
- SQLite database (.sqlite, .sqlite3, .db): The database file is opened read-only in the browser; you choose the table or view to import. Live database connections are not offered.
- Details, limits and troubleshooting: https://www.crosstabs.com/help/import-formats. Files are parsed in the browser and are not uploaded; database files are opened locally. Live data comes in through browser warehouse connections or the local Python package (crosstabs pull, crosstabs connect); see Public API and machine-readable discovery below.

## Public API and machine-readable discovery

- [OpenAPI 3.1 specification](https://www.crosstabs.com/openapi.json): Existing GET/POST aggregate contingency, chi-square, Fisher exact and odds-ratio endpoints, plus GET/HEAD health. No API key. Integer frequency counts only: 2–12 rows and columns, positive margins, grand total at most 1,000,000,000,000; POST body at most 16,384 bytes. Consult the specification for error shapes and unavailable-result conventions.
- [Developer documentation](https://www.crosstabs.com/developers): REST examples, the public aggregate MCP, and local MCP/CLI setup.
- [Aggregate-only MCP](https://www.crosstabs.com/api/headless-mcp): Five tools for public evidence and bounded counts; no respondent uploads or private project storage. Initialize MCP and call tools/list for schemas.
- [Local package](https://pypi.org/project/crosstabs/1.5.1/): Install with uv tool install --python 3.12 crosstabs==1.5.1 (uv brings its own Python; or pipx install crosstabs==1.5.1 with Python 3.10+, or run uvx crosstabs). crosstabs-headless also needs Node.js 22+. Add crosstabs-headless and crosstabs as stdio MCP commands using their full paths (uv tool dir --bin prints the folder). The project server reads only the folders listed in CROSSTABS_MCP_ALLOWED_ROOTS (set it in that server's env in the client configuration) plus a private exchange folder; get_runtime_status reports them. This is a published package, not a browser upload API.
- Statistics procedures (since crosstabs 1.5.0): the local headless MCP tools list_statistical_procedures and run_statistical_procedure run 110 SPSS-equivalent Statistics procedures on a local project file with the same engines as the browser Statistics mode. Respondent rows stay on the device. Weights must be a saved frequency weight (ordinary inference) or sampling weight (weighted estimates only; ordinary tests withheld); untyped weights are rejected. Complex Samples procedures (CSDESCRIPTIVES, CSTABULATE, CSGLM, CSLOGISTIC, CSORDINAL, CSCOXREG) run only on a survey design approved through define_survey_design. Seeded procedures report their seed; every result cites its reference-parity tests.
- Local data pulls (crosstabs 1.5 or later, run on the user's own machine): crosstabs pull runs one read-only SELECT/WITH query (database drivers as extras, e.g. pip install "crosstabs[postgres]>=1.5") and crosstabs pull <platform> fetches responses from Qualtrics, SurveyMonkey, Medallia, Alchemer, Typeform, Google Forms, Forsta/Decipher, QuestionPro, Jotform, SurveySparrow, REDCap, KoboToolbox, ODK Central or LimeSurvey (pip install "crosstabs[surveys]>=1.5"); both write a labelled .sav/.dta/.csv/.xlsx/.parquet file to open in the browser workspace and never apply or guess weights. crosstabs connect starts a loopback-only local bridge that hands a result to the workspace tab that opened it, paired with a one-time code. Credentials stay on the user's machine and rows never reach a Crosstabs server. Details: https://www.crosstabs.com/developers#local-data

## Agent interfaces

- [Local MCP](https://www.crosstabs.com/mcp): Install the published crosstabs 1.5.1 package with uv tool install --python 3.12 crosstabs==1.5.1 (or pipx install crosstabs, or run uvx crosstabs) and add crosstabs-headless and crosstabs as stdio MCP commands in Claude Desktop, Claude Code, Codex, Cursor or another local MCP client. The project server reads only folders listed in CROSSTABS_MCP_ALLOWED_ROOTS plus a private exchange folder. Files stay on your device; your AI client has its own data policy. The Codex plugin is installed from source and is not listed in any plugin directory.
- [Browser workspace](https://www.crosstabs.com/workspace): Open a survey file in the browser with no install or account; files are parsed on the device.
Local crosstabs 1.5.1 provides 37 local headless tools and, on the Python statistics server, 39 analytical tools, six market-research tools, database and survey-platform pull tools and runtime status (48 Python tools total). Guided weighting preview and apply are available with explicit population targets and human confirmation; saving a sampling weight does not approve a survey design or authorize ordinary inference. A published package does not mean the Codex plugin is listed in a plugin directory.
- [Local MCP setup, and Codex plugin](https://www.crosstabs.com/mcp): PyPI, Codex, Claude, parity, privacy, and release evidence.
