What does this tool do?

Check, repair, and export a safer CSV before import.

It is not a HubSpot or Shopify importer. It is the preflight step that helps you find risky rows, fix obvious issues, and avoid importing messy data into a live CRM or store.

Fix an Error Message

Pre-import report

Get a simple readiness score and a row-by-row issue table before your import creates a messy CRM.

Import-safe CSV

Export a safer CSV that excludes rows with blocking errors so you can review risky contacts separately.

No API required

The first version does not connect to HubSpot, Salesforce, or any CRM. It only checks your local CSV file.

Error message fixer

Paste failed import text and turn vague platform messages into a CSV fix plan.

Shopify image and option checks

Catch Image Src, duplicate image URL, Option1 Name, and option value problems before product import.

Shopify SEO and shopping fields

Review SEO Title, SEO Description, Image Alt Text, Google Product Category, gender, and age group fields before import.

Who is this for?

Sales ops teams, HubSpot admins, agencies, and small SaaS teams preparing contact lists for import.

What it does not do

It does not automatically import contacts, enrich leads, scrape data, send emails, or make legal/compliance decisions.

CSV import questions

Does CSV Import Fixer upload my CSV to a server?

No. The MVP runs in your browser and checks the CSV locally. You can export reports and safer CSV files without connecting to HubSpot or Shopify.

What Shopify CSV problems can it find?

It checks missing handles or titles, duplicate Variant SKU values, Image Src problems, option-column gaps, SEO metadata issues, Google Shopping fields, and rows that should be reviewed before import.

What HubSpot CSV problems can it find?

It checks duplicate emails, invalid emails, missing email values, phone formatting issues, company-name variants, lifecycle-stage warnings, and field mapping gaps.

Does it guarantee a successful import?

No. It prepares safer CSV files and highlights common risks, but HubSpot, Shopify, custom fields, and account settings can still affect the final import result.
