I need a program or Telegram bot for bulk creation of shipping documents through the Nova Poshta API.Main Task I upload 50–100 orders at a time into an Excel/Google Sheets/CSV table or paste a list of orders into the program. Clients provide data in different formats, so the system must automatically recognize the data, sort it into the necessary fields, and create shipping documents through the Nova Poshta API.Input Requirements Possible options: Upload an Excel/CSV file. Copy a list of orders into the program. Paste client messages in free format.What the Program Must Recognize From each order, it is necessary to determine: Recipient's full name; Phone number; City; Nova Poshta branch; Product/comment; Cash on delivery amount; Weight/dimensions, if specified.Operational Logic I upload 50–100 orders. The program processes each order. Data is automatically distributed into columns. The program checks the city and branch through the Nova Poshta API. If there is an error or missing data for an order, it highlights that order and indicates what needs to be corrected. If everything is correct, it creates the shipping document. After creation, it shows a list of completed shipping documents. It allows exporting the result to Excel.Output After Processing For each order, it is necessary to obtain: Shipping document number; Client's full name; Phone; City; Branch; Cash on delivery amount; Delivery cost; Status: created / error / needs verification.Mandatory Functions Bulk creation of 50–100 shipping documents at once; Verification of city and Nova Poshta branch; Ability to edit an order before creating the shipping document; Saving sender data; Working with cash on delivery; Exporting created shipping documents to Excel; Log of created shipments.Desirable Telegram bot or simple program for Windows; Excel/CSV upload; Ability to paste a list of orders as text; Saving a database of regular clients; Reordering with one click; Product and weight templates; Printing/downloading labels for packages.Important I need not just a form for manual filling, but a tool for bulk processing of orders.

Good afternoon. I need a keyword parser that outputs results through a Telegram bot. How it should work: Automatic search on 4 websites for keywords that change from time to time. Search queries are sent every few minutes. The words are uploaded in the form of a .txt file. The Telegram bot should have buttons: start bot, stop bot, download file (downloads a file with active keywords), upload file (uploads an edited file with new words). The bot should ignore previously found results, i.e., it should not indicate the same ad twice. The result comes to the bot in the form of a link with a photo, but just a link is sufficient. P.S. searching websites without API, VPS with 6TB and 50 IPs are already available. For detailed information, please contact me via private message.
