Contact

No response-time or availability SLA is currently offered. Please do not email source files, respondent rows, project exports, credentials, or other sensitive data. Crosstabs has no account, enterprise, or customer-data hosting agreement path.

Include with every issue

Browser and operating system.
File type and approximate row/column count. Never attach the source file, respondent rows, or a private project export.
Selected row variable, column variable, filters, weight variable, and missing-value setting.
Whether the issue occurs in CSV, XLSX, PDF, batch report, chart, local MCP, public MCP, or aggregate API.
Screenshot or copied warning text from the workspace.

Self-checks

For import issues, try a small CSV export of the same data to isolate spreadsheet formatting problems.
For public MCP or aggregate API issues, send only a minimal non-sensitive aggregate table, the request time, and the visible bounded error code. For local MCP issues, reduce the problem to a checked-in sample when possible. Never send private files, source respondent rows, project exports, OS usernames, or credentials.
For statistical warnings, check small expected counts, active filters, and whether a selected weight was blocked or a saved survey design completed successfully.
