Connect Fluent Forms to Google Sheets easily
Capture conversational forms, multi-step wizards, and payment entries from Fluent Forms in Google Sheets - complete with numeric calculations and real-time delivery.
CMS: WordPress
Overview
Fluent Forms is one of the lightest form plugins for WordPress, yet it packs conversational UI, multi-step layouts, and numeric calculations. LeadToSheet adds to this by piping every submission into Google Sheets in real time, so you can build dashboards, trigger automations, or share lead data with teammates who do not have WordPress admin access.
Implementation checklist
- 1
Embed the LeadToSheet snippet globally
Navigate to Fluent Forms > Global Settings > Custom CSS/JS or use a site-wide code injection plugin. Paste the script tag so it runs on all pages containing Fluent Forms.
LeadToSheet snippet
<script>(function(w,d,s,u,k,e){if(w.__formsync){return}w.__formsync={q:[],k:k,endpoint:e};var js=d.createElement(s);js.src=u;js.async=1;js.onload=function(){w.__formsync.init&&w.__formsync.init({ clientKey:k })};d.head.appendChild(js);})(window,document,'script','https://www.leadtosheet.com/sdk.min.js','YOUR_CLIENT_KEY','https://www.leadtosheet.com/api/ingest');</script> - 2
Check your input name attributes
Fluent Forms auto-generates names like "names[first_name]" for composite fields. Open a form preview, inspect the HTML, and note the name attributes. LeadToSheet uses these as column headers, so you may want to simplify them under the field's Advanced Options.
Tip: For the Name field, Fluent Forms nests first and last into a group. LeadToSheet creates separate columns like "names_first_name" and "names_last_name" automatically.

Walk through a multi-step form submission
Submit a test entry that progresses through every step of your multi-step form. LeadToSheet captures data only on final submission, not on intermediate step transitions, so all fields from all steps appear in one row.
Customization ideas
Track numeric calculation outputs
Fluent Forms can calculate totals, scores, or estimates. These calculated values are included in the form payload, so LeadToSheet writes the final number to your sheet. Use Apps Script to chart these values over time.
Understand what LeadToSheet captures from Fluent Forms
LeadToSheet captures text-based form field values only. It does not capture file uploads, PDF attachments, or hidden fields. If you need file URLs or PDF links in your sheet, use Fluent Forms' built-in export, webhook integration, or a server-side pipeline to log those URLs separately.
Segment conversational vs. standard form entries
The SDK auto-identifies each form via fingerprinting, so conversational and standard forms are recognised as separate forms. Map each to its own Google Sheet in the LeadToSheet dashboard to keep them separated.
Troubleshooting
Conversational form submissions not appearing
Fluent Forms' conversational mode uses a dedicated full-screen layout that may bypass your theme footer. Inject the LeadToSheet snippet via Fluent Forms' Global Settings custom code area, or use a plugin like WPCode that loads on all WordPress-rendered pages including custom templates.
Numeric calculation showing as NaN
If a calculation references a field the user left blank, Fluent Forms may submit NaN. Add default values to numeric fields in the builder or use Fluent Forms conditional logic to require dependent fields before the calculation step.
Duplicate entries after enabling payment confirmation
The SDK includes a 2-second de-duplication window that prevents identical submissions from being captured twice in rapid succession. If the confirmation page triggers a form event more than 2 seconds after the original submission, or with different field values, it may still appear as a duplicate row. Disable conflicting form-to-sheet plugins to avoid duplicates.

Frequently asked questions
- Is Fluent Forms' built-in Google Sheets integration different from LeadToSheet?
- Yes. Fluent Forms' native connector sends data server-side via their integration module. LeadToSheet captures at the browser level and adds UTM parameters, device data, and page context that the native integration does not include.
- Does LeadToSheet slow down Fluent Forms' lightweight performance?
- No. The LeadToSheet SDK is under 8 KB gzipped and loads asynchronously. It does not interfere with Fluent Forms' rendering or add any weight to the form itself.
- Can I capture both the conversational and classic versions of the same form?
- Yes. Each form instance is tracked independently. Whether a visitor sees the conversational or standard layout, their submission is captured with the form identifier and page URL.
