The spreadsheet block reads xlsx files and converts it into a live table. 
You can specify what cells should be editable. Editing fields will affect existing cell calculations.
For some reason WordPress prohibits the upload of <code>xslx</code> files. You can workaround this issue by renaming the file to <code>xls</code> (for now).
<h4>Usage</h4>
To use simply add a block to a page or post and choose ‘Spreadsheet block’. Upload an xls or xlsx spreadsheet file from the sidebar.
From the cell options (in the block) you can set which cells are editable and which cells will be rendered as table head.
Click the eye behind a sheet name to make specific sheets invisible.

<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>
