AI Mask a table

Names, companies, phones and e-mail become 【Person 1】 or 【Company A】 before ChatGPT or Claude sees the table. Then put the values back.

Other ways to hide

With "Keep the maths right", totals, shares and year-on-year changes come out right, and Put back gives the real amounts. The rough size can still be guessed. Not for work that needs the amount itself, such as a tax threshold.

"How many days later" stays right, and Put back gives the real dates. Not for work that needs the date itself, such as holidays or month ends.

How to hide

Keep the shape cannot be put back: a table from the AI cannot be restored. Keep AI Mask to put names back later.
