DataNormalizer

You can try DataNormalizer for free, with a cap of 25 rows per file, low processing priority and CSV only.

Paid plans are credit packs where one row costs one credit: $12 for 1,000 credits, $29 for 5,000, $49 for 10,000, $99 for 25,000, $249 for 100,000 and $990 for 1,000,000.

Every paid pack removes the row limit, adds Excel alongside CSV, gives the fastest processing and offers free reprocessing when a run hits errors.

DataNormalizer is an AI data normalization tool that standardizes messy spreadsheet data and fixes inconsistencies and errors automatically.

You upload a file, and DataNormalizer returns a cleaned version in CSV or, on paid plans, Excel.

It sits in the Excel AI and data analytics space, and it also lists an AI API and spell check among its categories.

The free tier is small, so it works as a test of the output on a sample before you spend anything.

Because billing is per row, the cost is easy to estimate: count the rows in your file and pick the pack that covers them.
