Spreadsheets hide the problem. A cell will take any length. The button, the tab, the table header, the push notification — those do not.

The usual misses are not typos. They are:

• a value that overflows the cell it was given

• a plural form that was never supplied

• a date or sort order that still follows the source language

• two halves of a sentence glued together so the grammar cannot move

• a placeholder that got translated, or dropped

• a term that meant one thing on screen A and another on screen B

None of that shows up if you only read the file. It shows up when the string is read in place, at the width the UI actually gives it.

That is the review. One language at a time. Priced per language. One payment.
