<h3>Usage</h3>
Prepare your file:
Supported formats: XLSX and CSV (UTF-8 encoding).
Required column:
<ul>
<li><code>sku</code> — used to match existing products; if a product with this SKU exists it is updated, otherwise a new product is created</li>
</ul>
Optional columns:
<ul>
<li><code>name</code> — product title</li>
<li><code>price</code> — regular price (numeric)</li>
<li><code>weight</code> — weight in kg (numeric)</li>
<li><code>description</code> — product description (HTML allowed)</li>
<li><code>images</code> — one or more image URLs separated by a pipe <code>|</code> (first image becomes the featured image)</li>
<li><code>categories</code> — category names separated by <code>/</code> (hierarchy) or <code>,</code> (multiple categories)</li>
<li>Any extra column is saved as a product meta field under the column name</li>
</ul>
Import flow:
<ol>
<li>Upload the XLSX/CSV file on the Import tab</li>
<li>Review column mapping on the Mapping tab if needed</li>
<li>Click Start Import — the batch runner processes rows in groups of 400 and shows progress in real time</li>
<li>When finished, a summary shows how many products were created, updated, and skipped</li>
</ol>
Media Loader tab:
<ul>
<li>Paste product SKUs with their image/video URLs to bulk-attach media</li>
<li>Or upload a ZIP archive — the loader matches files inside to products by SKU</li>
<li>Video files (mp4, webm, mov, etc.) are attached to the product gallery per SKU/filename</li>
</ul>
Logs:
Import logs are saved to <code>/wp-content/uploads/seganiko-fiw-logs/</code> and are also shown in the admin UI. Each log entry records the SKU, action (created/updated/skipped/error), and a short message.
<h3>External services</h3>
This plugin optionally connects to the ShortPixel Image Optimizer API to compress and optimize product images during the bulk media import process.
Service: <a href="https://shortpixel.com/" rel="nofollow ugc">ShortPixel</a> — an image optimization and compression service.
What it is used for: When the user enables the “Optimize images with ShortPixel” option in the Media Loader settings and provides a valid ShortPixel API key, uploaded product images are sent to ShortPixel for lossy or lossless compression before being stored in the WordPress media library.
What data is sent: The plugin sends the publicly accessible URL of each uploaded image along with the user’s ShortPixel API key and optimization preferences (compression type, EXIF handling). No personal user data is transmitted.
When data is sent: Data is sent only when the site administrator has explicitly enabled ShortPixel optimization in the Media Loader settings tab and triggers a bulk media import. No data is sent if the feature is not enabled.
Service endpoint: <code>https://api.shortpixel.com/v2/reducer.php</code>

SpreadsheetConverter

Import Spreadsheets from Microsoft Excel is a WordPress plugin that allows you to import live, calculating spreadsheets from Microsoft Excel to your blog or website in WordPress. The plugin is free but the calculating web page must have been generated with a paid license for <a href="http://www.spreadsheetconverter.com/" title="Link to the SpreadsheetConverter web site" rel="nofollow ugc">SpreadsheetConverter</a>, an add-in for Excel that converts the Excel spreadsheet to HTML and the formulas in Excel to JavaScript. The uploaded online spreadsheet is live and looks and feels exactly like in Excel. Now you can use Excel everywhere!
SpreadsheetConverter works like an Excel compiler creating live online spreadsheets in HTML and JavaScript. It is not a simple Excel viewer; the web spreadsheet plugin runs all your formulas in real-time – all the cells and charts are live!
You usually need to have your own WordPress server to install plugins. It may not be possible to install plugins on WordPress.com or other shared WordPress servers. If you are unable to use this plugin, you can use our <a href="https://help.spreadsheetconverter.com/support/online-help/publish-to-cloud" title="Link to the Publish to Cloud help page" rel="nofollow ugc">Publish to Cloud</a> service instead. It is built into SpreadsheetConverter and uploads the calculator to a cloud server. In most cases, this works just as well.
Note: before you upload a spreadsheet, you must use <a href="http://www.spreadsheetconverter.com/" title="Link to the SpreadsheetConverter web site" rel="nofollow ugc">the SpreadsheetConverter add-in for Microsoft Excel</a> to convert your spreadsheet to web format. To use this add-in, you must have Microsoft Excel 2007 or later for Windows – and the basic skills to create spreadsheets with it.

We’d love to help you try SpreadsheetConverter on one of your own spreadsheets. You don’t have to install the software to test it. Just send one of your own spreadsheets, and we’ll send it back as a live, intelligent web form or calculator. Use <a href="https://www.spreadsheetconverter.com/news/free-demo/" title="Link to the free-trial information page for for SpreadsheetConverter" rel="nofollow ugc">the online form</a> and remember to attach the spreadsheet!
This service is free, because it’s so simple to convert your spreadsheet to web format with SpreadsheetConverter that we can do it in almost no time at all. If you want to keep your web calculator or form up-to-date without ever installing or learning the converter, you can have us do all the conversion work for you, forever, using <a href="https://www.spreadsheetconverter.com/products/one-calculating-web-form-from-an-excel-sheet/" title="Link to the product page for paid one-time conversions" rel="nofollow ugc">the paid conversion service</a>.
