Sound familiar?
EHR exports have inconsistent date formats that break analytics tools
Patient birthdates in different formats cause age calculation errors in reports
Appointment data imports fail because date/time formats don't match the target system
Why Medical Data Analysts choose browser-based cleaning
You're preparing a patient cohort for a quality improvement study. The EHR export has birthdates in MM/DD/YYYY, admission dates in YYYY-MM-DD, and discharge dates as "Jan 5, 2024". Your analytics platform needs consistent ISO dates. HIPAA prohibits uploading this PHI to random cloud tools. CSVCleaner processes everything in your browser — no BAA needed because no data is transmitted.
