Built by someone
who has cleaned
too many CSVs.
I’m Noah Stambovsky. I work in marketing ops and revenue operations, which is a polite way of saying I spend an unreasonable amount of my life inside spreadsheets that are about to become someone else’s CRM.
I’ve done the 4:47pm Friday import. I’ve watched a routine contact update spawn 200 duplicate companies with no undo button. I’ve rebuilt the same file three times because the dates came out wrong.
Every one of those disasters had the same shape: the mess went in before anyone looked at it.
Garbage Out is the tool I kept wishing existed: a checkpoint between your spreadsheet and your system of record.
Upload the file, check the boxes for what needs fixing, preview exactly what will happen, and download the result. It doesn’t live inside your CRM and it doesn’t want a subscription to your data — it cleans the file and gets out of the way.
The file is yours.
So are the decisions.
Your data is yours.
The beta works in your browser. Your CSVs are not uploaded to our server or sent to AI services.
Preview before anything.
See the before-and-after before you download. Keep ambiguous matches visible rather than silently merging them.
Intelligence with a specific job.
AI-assisted column matching is planned at the schema level. The current beta uses known aliases and manual review.
General-purpose by design.
HubSpot, Mailchimp, GoHighLevel, ActiveCampaign. Keep file preparation separate from your system of record.
