The work before the work
You didn’t sign up
to be a data janitor.
Every import starts the same way: spreadsheet surgery before you’re allowed to do your actual job. Renaming columns. Hunting duplicates. Reformatting dates for the third time this month.
The mess went in
before anyone looked at it.
Three steps. Fewer surprises.
Before the import,
take a look.
Check the boxes.
Choose your cleanup, review column mappings, and decide which fields make a match.
Preview. Then download.
Compare the before-and-after. Review the exceptions. Take the cleaned file with you.
A toolkit for the ten minutes before import
Keep the records.
Lose the mess.
Tidy the details.
Trim whitespace, lowercase emails, preserve postal-code zeros, and normalize dates and phone formats with explicit settings.
Different headers. One file.
Bring differently shaped exports together. Review suggested field mappings and keep a source trail for every row.
Make the match explicit.
Add run-local Wizard IDs using complete match keys. Keep source IDs separate from destination CRM IDs.
Dedupe without the blindfold.
Remove exact matches using first-row or most-complete rules. Flag similar records for review, with both rows intact.
Find the “why won’t this import?” before you import.
See invalid emails, ambiguous dates, missing fields and migration conflicts in an issue report that tells you what needs attention.
Meet your data where it’s going
Prep for your platform.
Choose a destination and the record type. The beta provides basic cleanup presets; portal-specific owners, consent, custom properties and associations still need review.

Fair questions
Before you hand over a file.
Do you store my data?
The beta processes your CSVs locally in your browser. Files aren’t uploaded to our server. Refreshing clears the working session; downloaded files stay on your computer.
Does it write directly into my CRM?
No. You download a file and import it yourself, after reviewing the results and your destination’s import settings.
What’s available in the beta?
Multi-file cleanup, reviewed column mapping, exact dedupe, possible-duplicate flags, formatting, issue reports and CSV migration trials. Fuzzy matches are flagged for review, never automatically merged.
What does the AI do?
AI-assisted schema matching is planned. Today’s beta uses known column aliases and your reviewed mappings. It makes no AI calls.
What does it cost?
The current demo is free and needs no account or credit card. It accepts up to five CSV files, each up to 5 MB and 5,000 rows. Launch pricing and paid tiers are still being finalized.
