FAQ

Can Coupler.io import data from a folder and watch for new files?

No, Coupler.io doesn't support folder monitoring or automatic detection of new files. You must specify a single file URL for each data flow. However, if new files land in a folder daily with the same name, you can use a tool like Integromat to rename/copy them to a consistent location, then point Coupler.io to that location.

Can I import multiple files at once without creating separate data flows?

Not directly—each data flow points to one file. However, you can import multiple sheets from the same spreadsheet in one data flow, and consolidate them with Append. If your files are in different spreadsheets, create one data flow per file and use Join or Append transformations in your destination.

What happens if I update the source file—does Coupler.io automatically pick up the changes?

Yes, if you edit the same source file. When your scheduled data flow runs, it re-imports the current data from that file. However, if you replace the file (even with the same name), Coupler.io will still reference the old file by its ID. You must update the file URL in your data flow settings to point to the new file.

Can I import graphs or charts from Google Sheets?

No, Coupler.io only transfers table data (rows and columns). Charts and graphs must be recreated manually in your destination. You can import the raw data that powers a chart, then recreate the chart in your destination tool.

What file formats are supported?

Coupler.io supports:

• Google Sheets

• .xlsx (Excel)

• .xlsm (Excel with macros)

• .csv (comma-separated values)

Other formats like .xml, .json, .pdf, etc., are not supported.

Why does my CSV file show "undefined" or won't load?

CSV files must be shared with your Google account (just like any other file in Google Drive). If you're importing a CSV that's not explicitly shared with you, Coupler.io can't access it. Also, verify the file is UTF-8 encoded—non-standard encodings can cause load failures.

Can I specify which sheets to import from a spreadsheet with 20+ tabs?

Yes, in the "Sheet(s)" parameter, enter the exact titles of the sheets you want to import, one per line. Coupler.io will import and combine only those sheets (using Append transformation).

How do I import only a portion of my sheet?

Use the "Range" parameter. For example, A1:Z100 imports only columns A through Z and rows 1 through 100. This is useful for skipping headers, footers, or large unused sections.

Why am I getting quota or rate limit errors?

Google Sheets API has rate limits. If you're running multiple data flows at the same time, you'll hit these limits. Spread your data flow schedules across different times—for example, run one at 8:00am, another at 8:15am, etc. Avoid running all of them simultaneously.

Can I send imported data to an AI tool like Claude or ChatGPT?

Yes! After importing data from Google Drive, you can set your destination to Claude, ChatGPT, Cursor, Gemini, Perplexity, or OpenClaw. This lets you analyze or transform the data using AI in the same workflow.
