Most Excel files are under 5MB.
But sometimes you have the huge MegaFile.xls that is much bigger.
File size limits are currently set to 15MB per file.
If you have a larger file, just please email firstname.lastname@example.org or chat in on the site and we can enable your account to upload files up to 50MB.
The absolute max file size is 200MB. We cannot process any spreadsheets larger than that.
NOTE: These limits also apply to Dropbox and Box file uploads.
