ARCED DataFlow Reviews and Details

ARCED DataFlow is a desktop app for Windows, macOS and Linux that checks field survey data while the team is still in the field. It connects to SurveyLoopr, SurveyCTO (encrypted forms too), ODK Central and KoboToolbox, or reads CSV and Excel exports from any other tool, and checks every interview the moment it syncs.

What it does

• Reads your form and sets up high-frequency checks: duplicates, outliers, ranges, logic across questions, missing answers, "don't know" and refusals, "other, specify" answers, GPS, and signs that interviews may be made up (six statistical signs per enumerator, compared with the rest of their team).
• Puts every flag in one ranked list, with a fix prepared for each. A person approves every fix.
• Never changes the raw data. Each correction is logged with who, when and why, can be undone, and lands in a Stata do-file that rebuilds the clean data from the raw data.
• Exports to Stata, R, Excel and CSV, and builds a Field Report: one HTML file with progress, team performance and the problems fixed, which opens in any browser without an install or login.

Privacy

DataFlow runs on your computer and talks only to your own survey server. Its AI models run locally and work offline, so no data goes to an AI service. Raw interviews with personal data can be kept in an encrypted vault that also opens in VeraCrypt, and downloads are de-identified by default.

Background

DataFlow grew out of arceddataflow, the Stata workflow ARCED Foundation uses to clean its surveys. It is made by ARCED International, the makers of SurveyLoopr. Its duplicate and outlier checks are tested to flag exactly what arceddataflow flags.

Pricing

7-day free trial. $19 per seat a month, or $99 a year with 5 seats. Every feature is in every plan. A sample study with 600 interviews can be explored without an account.
