Import Bitrix goods from 1s, advice?

Question

1C-Bitrix

Guys, I am writing a site on Bitrix from scratch. No modules, no standard tools.
I will need to import goods from 1c to Bitrix.
Need advice on how to do it better?
Or write your own parser, then which one - csv or xml?
Or maybe Bitrix has some standard import tools or maybe you know adequate free modules.
Tell me what is the best way to do it?

Answer 1

Refer to the original source. Look at the manual on regular fozmozhnosti. There it is well described how the exchange is done, incl. proposed exchange formats. You can look at the info-art where they sold uploads for info blocks.
But keep in mind that the exchange possibilities and the editing of Bitrix.

Answer 2

For Bitrix there is a CommerceML data exchange format. Use it.

Answer 3

maybe Bitrix has some standard import tools or maybe you know adequate free modules.

There are standard tools, but as far as I remember, the minimum edition is "Small Business" (the module itself is called "Online Store").
Algorithms and formats are described in the documentation: https://dev.1c-bitrix.ru/api_help/sale/algorithms/...
By the way, there you can get information about formats, file contents, and in general a lot of interesting things. Considering that the module itself for 1C is free, you can always implement your own implementation according to this algorithm

Or write your own parser, then which one - csv or xml?
Tell me what is the best way to do it?

Better - use regular mechanisms.
Because:
1) You can always contact the TP for a solution to the problem
2) It’s easier to find a specialist and diagnose the problem
3) If you keep everything up to date and don’t be too zealous with customizations, you get the best solution with almost no investment

Answer 4

If time allows, write your own.
