reeqee

reeqee lets you analyze Excel and CSV files just by asking questions in German. It's for anyone who works with spreadsheets but doesn't want to write formulas or SQL queries. This is especially useful for accountants, tax advisors, and other professionals who need quick answers from their data. Your files are processed locally. They never leave your browser.

The tool's main benefit is privacy. It runs entirely in your browser using WebAssembly, so your sensitive spreadsheet data isn't uploaded to a server. Only your question and the column names from your file are sent to an AI to generate the database query. The actual contents of your spreadsheet rows remain on your computer, which helps with GDPR compliance.

You can upload a file and immediately start asking about its contents.

• Natural language queries: Ask things like "Which invoices are more than 30 days overdue?" in plain German.
• Multiple files and sheets: Analyze several files or sheets at once. reeqee automatically matches columns with the same name across them.
• Export results: View your answers as a table directly in the browser or export them as a new CSV or Excel file.

reeqee also includes free, browser-based tools that don't use AI. You can convert between different spreadsheet formats (like CSV to XLSX) or view German XRechnung e-invoices as a simple table.
