How it works

How FixCSVData works

Upload your analytics CSV, choose a destination, review the data quality scan, and export clean data.

Upload product events, usage exports, app logs, tracking data, or warehouse query results.

Select Mixpanel, Amplitude, Segment, PostHog, BigQuery, Snowflake, or a custom schema.

FixCSVData finds timestamp problems, schema conflicts, broken event names, missing properties, duplicate events, and user ID issues.

Download clean CSV, JSONL, schema mapping, tracking plan summary, and data quality report.

What FixCSVData checks

Automatically maps user IDs, event names, timestamps, properties, session IDs, account IDs, and device fields.

Groups signup_complete, Signed Up, sign-up-completed, and SignupCompleted into one clean event name.

Converts inconsistent date formats, Unix timestamps, and ambiguous time values into a single consistent format.

Normalizes plan names, device types, boolean values, source fields, and metadata keys.

Identifies repeated events triggered by the same user within the same timestamp window.

Flags missing IDs, mixed ID formats, anonymous users, and conflicting account IDs.

Generates an organized event taxonomy by activation, engagement, retention, billing, admin, and integration.
