Астрологи объявили неделю регулярных выражений.
Так что мы продолжаем эту тему и сегодня напомним, что их можно использовать и в проверке данных.

Допустим, вы хотите разрешить ввод только кодов цветов в шестнадцатеричной форме.

Тогда можно использовать REGEXMATCH — эта функция будет возвращать TRUE / ИСТИНА, если текст, соответствующий регулярному выражению во втором аргументе, будет найден в текстовой строке из первого аргумента.

В случае проверки данных формула будет выглядеть так:
=REGEXMATCH(первая ячейка диапазона с проверкой ;"рег выражение")

В случае с кодами цветов:

=REGEXMATCH(A2;"^#[0-9A-Fa-f]{6}$")


То есть решетка + 6 символов из набора "все цифры, строчные и прописные буквы от A до F". Чтобы разрешить ввод только кодов (то есть в ячейке не должно быть больше ничего), добавляем ^ и $ (начало и конец строки).

Telegram Gives Up On Crypto Blockchain Project

Durov said on his Telegram channel today that the two and a half year blockchain and crypto project has been put to sleep. Ironically, after leaving Russia because the government wanted his encryption keys to his social media firm, Durov’s cryptocurrency idea lost steam because of a U.S. court. “The technology we created allowed for an open, free, decentralized exchange of value and ideas. TON had the potential to revolutionize how people store and transfer funds and information,” he wrote on his channel. “Unfortunately, a U.S. court stopped TON from happening.”

Telegram Q&A
Q: How does hottg.com work?
Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.

Q: What is Telegram? What do I do here?

What's more, there is no need to worry about disk space on your device. With Telegram's cloud support and cache management options, Telegram can take up nearly zero space on your phone.

Q: How is Telegram different from WhatsApp?

Unlike WhatsApp, Telegram is a cloud-based messenger with seamless sync. As a result, you can access your messages from several devices at once, including tablets and computers, and share an unlimited number of photos, videos and files (doc, zip, mp3, etc.) of up to 2 GB each. And if you don't want to store all that data on your device, you can always keep it in the cloud.Thanks to our multi-data center infrastructure and encryption, Telegram is faster and way more secure. On top of that, Telegram is free and will stay free — no ads, no subscription fees, forever.
