Sponsored cleanups
Some cleanups on Clean That Sheet™ are covered by a sponsor. When a sponsored cleanup is available for your file, it is applied automatically on the preview screen before you pay, and the page tells you who covered it. Sponsored access is limited and funded by our partners, so there is no public discount code to enter.
“We've found this tool to be a great fit for the kind of spreadsheet work we do at Lombard Toyota. It helps turn large, messy data exports into something much easier to read and work with, without requiring a lot of manual cleanup.
What we especially like is that it seems to understand the structure of dealership data instead of treating every column the same. That saves time and makes the finished spreadsheets much more useful for our day-to-day work.
Definitely a helpful tool for an automotive dealership working with a lot of data.”
