The file stays in this browser. RenewalDock does not receive it.
A safer handoff
Fix the sheet before reminders depend on it.
The cleaner standardizes operational renewal data. It does not verify a license, policy, permit, inspection, contract, or regulatory requirement.
Map and review
Match your headings and see exactly which rows are clean, invalid, duplicated, or normalized.
Download or track
Keep the clean CSV, or create a workspace to add reminder delivery, owners, next actions and history.
Plain boundaries
Useful cleanup, without pretending to certify the record.
Does RenewalDock receive my spreadsheet?
Not in this public cleaner. The browser reads the selected file and generates the download locally. An authenticated import sends the original CSV only after you explicitly confirm it.
Will this fix invalid rows automatically?
No. Invalid dates, missing required values and duplicate rows are left out and explained so you can correct the source. Unknown categories are normalized to Other and clearly disclosed.
Does a clean row mean the renewal is valid?
No. “Clean” only means the row matches the spreadsheet format. Confirm current status and requirements with the issuing authority, carrier, contract owner or other authoritative source.
