Browser-native German text-to-SQL for CSV and Excel: ask in plain language, run DuckDB-WASM locally, send only schema and the question to Mistral in the EU.

reeqee is a Berlin-operated browser app that lets business users ask questions about CSV and Excel files in everyday German. It turns the question into SQL, runs that query locally with DuckDB-WASM, and shows a table you can export. Spreadsheet cell values are not uploaded for analysis.

It exists for DACH accounting, tax advisory, controlling, and SME teams that live in DATEV, ERP, or bank exports and do not want to write formulas or SQL. The product is sold as B2B SaaS to entrepreneurs under German law, not as a consumer tool.

The concrete differentiator is the data path: according to the vendor, only the natural-language question and column schema go to Mistral AI in France, while row contents stay in the browser. The app itself is hosted on Hetzner in Germany.

EU-operatedBrowser-local SQLGerman NLP queriesSchema-only AI pathB2B DACH focus

Shortlist reeqee when a DACH team needs German natural-language queries on CSV/XLSX with local row processing and an EU LLM that only receives schema. Skip when you need a full spreadsheet suite, server-side warehouse analytics, independent security audits, or consumer licensing. Consider Microsoft 365 Excel or Google Workspace for authoring, and LibreOffice or Nextcloud for European office/file workflows that are not text-to-SQL.

Key capabilities

Users upload CSV or Excel, ask in everyday German, and receive a generated SQL query plus a result table. Aimed at accountants and SME staff who will not write SQL or complex formulas.

Row data is processed in the browser with DuckDB-WASM according to the vendor. Analysis does not require uploading table contents to reeqee servers, which helps with sensitive DATEV or bank exports.

The privacy policy states that only the question and column names go to Mistral AI SAS in France for SQL generation and suggested questions. Cell values are excluded from that path.

Paid workflows include linking multiple files or sheets with column matching, then exporting results as Excel or CSV. Plan limits differ between single-file and multi-file tiers.

A separate converter turns files between XLSX, XLS, ODS, and CSV variants entirely in the browser without calling the AI, useful for UTF-8 and delimiter fixes.

Best fit when

  • German-speaking accounting, tax, controlling, or SME operators querying CSV/XLSX exports without SQL skills
  • Teams that want row data to stay in the browser and only send schema plus questions to an EU LLM
  • Buyers who need a narrow analysis tool beside Excel/DATEV exports rather than a full office suite
  • Organisations that prefer German-law B2B contracting with Berlin-based sole-trader operation and Hetzner DE hosting

Poor fit when

  • Teams that need collaborative spreadsheet authoring, macros, or a full Microsoft 365 / Google Workspace replacement
  • Workloads that require server-side data warehouses, scheduled pipelines, or multi-tenant governed datasets
  • Buyers that require ISO 27001, SOC 2, or an independent no-logs/security audit before shortlisting
  • Consumer or personal use cases (AGB limit the offer to entrepreneurs and public-law entities)

Consider instead when

  • When: You need a full European spreadsheet client for creating and editing workbooks offline

    Consider: LibreOffice

    LibreOffice is an office suite, not a text-to-SQL assistant.

  • When: You need EU file sync, sharing, and office collaboration rather than ad hoc CSV questioning

    Consider: Nextcloud

    Complementary stack: store in Nextcloud, analyse exports in reeqee if the AI path fits.

  • When: Analysts already live in Excel/Sheets and only need formulas, Power Query, or pivot tables

    Consider: Microsoft 365 Excel or Google Workspace Sheets

    Stay in the incumbent suite if natural-language German querying is not the bottleneck.

Considerations & known limitations

  • HighAI SQL can be wrong

    AGB disclaim correctness of generated SQL and results. Customers must validate before tax, accounting, or business decisions. Practical impact: treat outputs as assistive, keep human review of the shown SQL.

  • MediumQuestions and SQL are logged

    Privacy policy stores question text, generated SQL, success flag, and timestamp. Even if row data stays local, question text may itself be sensitive. Object via hello@reeqee.de per the policy.

  • MediumNo public independent audit

    Local-processing and schema-only AI claims are first-party. No ISO 27001, SOC 2, or public security audit was found. High-assurance buyers will need contractual evidence and technical due diligence.

  • MediumSole-trader operator scale

    Legal entity is a Berlin sole trader, not a GmbH with published certs or status page. Fine for many SME tools; weaker for enterprises that need vendor risk tiers, SLA percentages, or succession guarantees.

  • LowRenewal wording inconsistency

    Pricing page text and AGB renewal clauses have differed on automatic extension. Confirm the signed terms before budgeting renewals.

Open questions for due diligence

  • Will the vendor sign a customer DPA and provide a complete subprocessor list including backup/DR?
  • Is there an independent review of the browser build proving row data never leaves the client?
  • Which exact Mistral model/endpoint is used, and how are prompt logs retained on Mistral's side?
  • Which renewal and cancellation terms govern paid plans when pricing page and AGB wording diverge?
  • Are there documented row/size limits for DuckDB-WASM on typical office laptops?

Preguntas Frecuentes

According to the homepage, privacy policy, and AGB, CSV/XLSX contents are processed locally with DuckDB-WASM and are not uploaded for analysis. Only the natural-language question and column schema are sent to Mistral AI in the EU. This is a first-party claim; there is no public independent audit of the client build.

The privacy policy says reeqee stores the question text, the generated SQL, success status, and a timestamp for product improvement. It states that file contents and column names are not stored in that log. Users can object by emailing hello@reeqee.de.

The AGB state the service is offered exclusively to entrepreneurs under § 14 BGB and public-law entities, not to consumers under § 13 BGB. Procurement should treat it as B2B SaaS under German law with Berlin venue.

Published processors include Hetzner Online GmbH (Germany hosting), Mistral AI SAS (France, schema and questions only per vendor), and Mollie B.V. (Netherlands payments). Analytics are described as self-hosted Umami on Hetzner. A full public subprocessor register beyond the privacy policy was not found.

The AGB disclaim correctness of AI-generated queries and require customers to check results before business, tax, or accounting use. The product is positioned to show the SQL for human review. It is an assistant for exploration, not an audited reporting engine.

reeqee offers a time-limited trial without payment details, then annual prepaid Solo/Pro plans (Team listed as coming soon) billed through Mollie, with an invoice option. Confirm renewal and cancellation terms in the live AGB and pricing page before purchase; those pages have differed on auto-renewal wording.
