Workflow

How it works

Four steps from messy export to import-ready analytics data.

01

Upload your analytics CSV

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

02

Choose your destination

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

03

Review the data quality scan

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

04

Export clean data

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

Capabilities

What FixCSVData checks

Seven checks that catch the issues blocking Mixpanel imports and breaking warehouse loads.

01

Event schema detection

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

02

Event name normalization

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

03

Timestamp repair

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

04

Property cleanup

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

05

Duplicate event detection

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

06

User ID checks

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

07

Tracking plan summary

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