Need a parser for the online store https://www.lcsc.com/

Hello!

I looked at the website and the task — everything is clear.

The key point that is important for such a volume (650k products):
LCSC gives no more than 5000 products per request through the internal JSON API. Therefore, I will use a recursive traversal of subcategories with micro-filters — so that each selection is below the limit.

What I will implement:
— Python script with direct requests to the LCSC JSON API (faster and more stable than parsing HTML)
… — Filter for "In Stock" products only
— Progress saving (checkpoint) — if the script is interrupted, it continues from where it left off, not from the beginning
— Progress logging — shows how much % has been collected
— Export to XLSX exactly according to the requirements.

Hello.

The task is clear: I need a stable script that can be run regularly to obtain an up-to-date XLSX of LCSC products only with the status In Stock, rather than a one-time parsing.

I looked at the example file: the structure is clear - section, MPN, Manufacturer, Availability, Description, Package, and 4 pairs of Quantity/Price. I will export in the same format so that the file can be used immediately afterwards.

With this volume, it is important not to parse HTML "head-on," but first to check the internal API requests of LCSC. This is faster, more stable, and easier to maintain when the website changes. I would also include progress saving, retries on errors, logging, and the ability to restart without losing already collected data.

My stack: JavaScript/TypeScript, REST API, data handling, and automation. I can create a script with manual execution, and if necessary, prepare a version for monthly execution.
…
Question: do you need only the final XLSX after each run, or do you also need an intermediate cache/database to update the data faster on the next run?

Good day! I have written turnkey parsers for electronics catalogs — with pagination, the "In Stock" filter, and exporting price tiers to XLSX, so I will make the format with your 8 columns for quantity/price exactly as needed. For this volume (650k items), I will collect data through their internal API — it’s faster and more stable than HTML, and the script will remain restartable every month. Approximately 4-5 days. Please let me know if you only need available products now or the entire catalog with availability markings?

Hello! I see that the project budget allows for a serious approach to the task. 650,000 products is a load that requires building a real Data Pipeline, not just a simple parsing script.
My solution is to create a reliable data collection system that will guarantee completion, even if the internet goes down or the site temporarily blocks the IP.

Why my solution is an investment, not just code:

1. "Resumable Download" Architecture: The biggest problem when collecting 650k records is interruptions. My software saves the queue state in SQLite. If the script crashes at the 300,000th record, you can restart it, and it will continue from product 300,001, not start from zero.
2. Professional data handling (Stream processing): The script does not overload the RAM. It reads and writes data in a streaming manner, so even a file of hundreds of megabytes can be generated on any VPS.
3. API-First approach: I will not simulate button presses. The script works directly with the site's internal JSON API. This ensures maximum speed (milliseconds per request) and longevity (the script won't "die" when the site's design changes).
4. Scalability for modifications: The code is written based on clean PHP classes (SOLID). If the data structure on LCSC changes or you need to add a new column, this can be done by changing 3-4 lines in the configuration.
… 5. Protection against bans: Built-in proxy rotation logic, simulation of "human" pauses, and handling of HTTP errors (429, 503) to bypass LCSC's anti-fraud systems.

• Technologies: Pure PHP 8.x (CLI), Guzzle (Async), SQLite (state management), FastExcel.
• Cost: 16,000 UAH (full development, proxy logic setup, and launch instructions).
• Timeline: 6 days (including time for stress tests).

I offer engineering quality that will save you the need to hire someone to maintain this script in the future. Ready to start working!

Hello!

The task is clear: it is necessary to regularly collect all "In Stock" items from LCSC across all sections of the catalog and export them to XLSX in a clearly defined format.

What I can deliver:
— a stable parser for a large volume of data (~650,000 items) that goes through all categories;
— export to Excel with the required columns: section, MPN, Manufacturer, Availability, Description, Package, Pricing;
— a button to run or a schedule + the possibility for further refinement if the catalog structure changes.

… I work with Python, large parsing, Excel export, and maintaining such scripts, so I can create not just a one-time collection, but a working tool for regular use.

Hello!

I have reviewed your technical specifications and the attached example file. The task is clear: I need a regular dump of the LCSC.com catalog (only "In Stock" items, about 650k positions) with the correct breakdown of the wholesale pricing grid (Quantity/Price up to 4 levels) in XLSX format.

I am a Python developer specializing in creating high-load parsers and working with data pipelines.

Many developers suggest parsing such sites through browser emulation (Selenium), but with a volume of 650,000 items, this would take days.

Here’s how I will implement this parser (Solution Architecture):
…
Direct work with the Backend API: LCSC.com dynamically loads products through hidden JSON API endpoints. I will write a script that will directly call these APIs. This will speed up data collection by 100 times.

Bypassing the limit of 5000 items: The platform does not allow scrolling through more than 50-100 pagination pages at a time. To extract all 650k, I will write a deep crawl algorithm that will recursively delve into subcategories and apply micro-filters to ensure each sample has fewer than 5000 items.

Speed and stability: I will build the script on an asynchronous engine (Aiohttp/Asyncio). We will implement proxy rotation (the proxy will be included in the budget) and a retry system. If LCSC temporarily blocks the IP, the parser will simply switch proxies, wait a few seconds, and continue from where it left off.

Generating XLSX: Dynamic parsing of the pricing tiers and writing in the format you need (8 columns for prices) using the pandas library. The file will not weigh gigabytes and will easily open in Excel.

The script will be equipped with a config and a detailed logger (so you can see what percentage of the catalog has already been collected). If the site structure changes (if they update the API), the code is easily scalable and modifiable, as I write in strict OOP style.

I am ready to start immediately. Message me privately, and I will show you exactly how we will extract the pricing matrix!

Hello. I understand the task: a script is needed that, upon launch, traverses the entire catalog of lcsc.com across all sections, takes only In Stock items, about 650,000 positions, and exports them to XLSX with columns for section, MPN, manufacturer, availability, description, casing, and price pairs for quantity and price at four levels. It should run once a month or manually, plus the ability to adjust for changes in the catalog structure.

Regarding implementation: lcsc has an internal JSON API that provides the catalog page by page, so I would primarily look into working directly with these requests rather than parsing HTML. This is faster, more stable for a volume of half a million positions, and easier to fix when changes occur. If part of the data is closed or protected, I would add Selenium only to problematic areas.

With a volume of 650,000, stability is crucial, so I would implement resumption from the point of interruption, duplicate control by MPN, careful pauses, and retries against anti-bot measures, with proxies if necessary, plus progress logging so that the run can be restarted without losing collected data. The export to XLSX should be done via pandas or openpyxl with exactly the column structure specified in the technical specifications, including four pairs for quantity and price.

I have been creating parsers in Python with Selenium, BeautifulSoup, and pandas for a long time. To assess more accurately: are the price levels needed specifically those shown for retail quantities, or are all wholesale tiers from the product page important? This affects how many requests per position are needed. I am ready to start by analyzing the structure of their API in several sections to fix the export format and timeline.

Good afternoon.

I looked at the example file — the structure is clear, the task is straightforward.

I propose a Python script with two modes of operation:

1. Through the LCSC API — if access is available:
— Batch requests of 100–200 products at a time
— 650,000 products — about 1–2 hours
…
2. Through Playwright (browser parsing) — if the API is unavailable:
— Page by page, bypassing anti-bot protection
— 650,000 products — 8–12 hours, I recommend running on a VPS

What will be included in both cases:
— Crawling all sections, filter "In Stock"
— Exporting 14 columns in the format of your example
— Saving progress (checkpoint) — if the script is interrupted, it continues from where it left off
— Documentation and the ability to edit if the website structure changes

Cost: 8,000 – 12,000 UAH. Deadline: 5–7 days.

Please clarify: do you have access to the LCSC API?

Hello!

I have reviewed your task and looked at the attached example CSV file. The task is completely clear — you need a parser for the site lcsc.com that will gather the necessary data on components and accurately reproduce the table structure you require.

Here’s how I will implement it:
I will write a reliable script in Python. If the site uses dynamic loading or protection, I will use tools to simulate a real browser to avoid blocks. The script will automatically go through categories/links, collect item numbers, prices, and other characteristics, and then generate a ready file (CSV/Excel) exactly according to your template.

The code will be clean and documented so that you can run it independently in the future. If needed, I can package everything in Docker.

… Clarifying question:
Is the parsing needed once (just to gather the database for now), or should this script run regularly to update stock and prices?
