SpreadsheetConverter Calculator

SpreadsheetConverter (https://www.spreadsheetconverter.com/) turns an Excel workbook into an interactive, calculating web page. This plugin embeds that calculator in WordPress as a Gutenberg block — rendered inline by your theme (no iframe), SEO-visible, and recalculating live as visitors type. Two hosting modes: Host on this site (recommended) — paste the conversion link copied from the SpreadsheetConverter task pane in Excel and click Host on this site. WordPress fetches the calculator from the SpreadsheetConverter cloud and stores it inside your own site (wp-content/uploads/ssc-embed/). Everything is then served same-origin — fast, no CORS, and the calculator keeps working forever, even after the conversion link expires. Link to the cloud — click Publish to Cloud in Excel, paste the permanent link. The calculator stays on the SpreadsheetConverter cloud; your page references it and is always current when you re-publish. An offline fallback lets you upload the calculator zip manually if your WordPress host cannot reach the SpreadsheetConverter cloud. Classic (non-block) themes can use the [ssc_calc] shortcode. One calculator per page. The block validates the pasted link and tells you exactly what to do if it is the wrong kind (for example a temporary “Test in Cloud” link). External services This plugin connects to the SpreadsheetConverter cloud in two situations, both initiated explicitly by an editor — never on a public page view in self-host mode: Host on this site — when an editor clicks the button, the WordPress server downloads the calculator bundle from the conversion link’s host (*.spreadsheetconverter.com). The pasted URL (containing the conversion job id) is the only data sent. Link to the cloud — the page embeds the calculator directly from the SpreadsheetConverter hosting cloud (*.spreadsheethosting.com); visitors’ browsers request the calculator files from that host. When configuring the block, the WordPress server fetches the published calculator’s index page once to read its name. Both services are provided by Framtidsforum I&M AB (SpreadsheetConverter). Terms of use: https://www.spreadsheetconverter.com/terms-of-use/ Privacy policy: https://www.spreadsheetconverter.com/privacy-policy/ Getting started Part 1 — Convert your spreadsheet (in Excel) Start Excel and open your workbook — e.g. mortgage-calculator.xlsx. Open the SpreadsheetConverter task pane (Home ribbon → SpreadsheetConverter). Sign in if prompted (required to convert). Press Convert. The spreadsheet becomes an interactive web calculator (a few seconds). Copy the link for the path you want: To host it on your own WordPress site (recommended): after Convert, click Copy link. Use it within a few minutes (it is a short-lived conversion link). To link to the SpreadsheetConverter cloud instead: first click Publish to Cloud, then Copy permanent link. Only a Publish to Cloud link works for cloud-linking — a conversion link, or a temporary “Test in Cloud” link (its address contains /tmp/), is rejected by the block. In both cases you paste the whole link and the block double-checks it. Nothing is downloaded to your computer. Part 2 — Add it to your WordPress page Open your WordPress page for editing (Pages → Add New). You are already signed in to WordPress here — that is why you never type a password into Excel. Add the SpreadsheetConverter block (＋ → “SpreadsheetConverter Calculator”). Paste your link. The block recognizes the link type and offers the matching option: Conversion link → Host on this site (recommended). Click it. WordPress fetches your calculator and stores it inside your own site. Publish-to-Cloud link → Link to the cloud. The calculator stays on the cloud; your page references it. Temporary “Test in Cloud” link → the block shows: “This is a temporary test link — click Publish to Cloud in Excel for a permanent one.” Anything unrecognized → “That doesn’t look like a SpreadsheetConverter link — copy it again from the Excel panel.” See the live preview inside the editor — no grey iframe, theme-styled, calculates live. Press Publish (the WordPress button). The page goes live. View your live page. It calculates, validates, moves between sheets, and Submit works.
