Move a spreadsheet between platforms without guesswork.

Convert CSV and XLSX exports between DealMachine, Google Contacts, Outlook, QuickBooks Online and WooCommerce with a fixed rule engine. Preview compatibility free before you pay for converted output.

Preview is analysis only — it does not produce a converted file. Paid conversions start at $9.

Deterministic by design. Conversion is performed by a fixed, versioned rule engine. Gridlyst does not use AI, machine learning or any probabilistic model to decide conversion semantics, invent field values or fill gaps in your data.

Deterministic, not generative

A fixed, versioned rule engine performs every conversion. The same file and the same decisions always produce the same output.

Preview before you purchase

See row counts, field coverage, compatibility and every lossiness decision first. Payment comes after you know what you are getting.

Private by default

Uploads and converted output stay in private storage, released only through short-lived signed links to your own workspace.

How a Gridlyst conversion runs

1. Upload and analyze

Upload a CSV or XLSX export, pick the source and destination, and Gridlyst analyzes the file to report row counts, field coverage and compatibility.

2. Review lossiness and decide

Where a field cannot be carried across without a choice, the engine reports the exact options it supports and you decide before anything is converted.

3. Deterministic conversion

The same input, the same decisions and the same engine release always produce the same output. No guessing, no generated values, no run-to-run drift.

4. Authorized download

Converted output is written to private storage and released through a short-lived, signed download link to your workspace only.

Supported conversions

Beta: DealMachine, Google Contacts, Outlook, QuickBooks Online and WooCommerce adapters are labelled Beta until production certification is complete. Run a preview to see exactly how your own file is handled.

What the free preview includes

Preview is a compatibility check, not a free conversion.

Included: uploads up to 25 MiB, analysis of up to 10,000 rows, 5 previews per workspace per day, full compatibility and lossiness report.

Not included: no converted file, no converted download, no API access. Source files are retained for 24 hours.

Check your own export against the destination first.

Upload a CSV or XLSX file, read the compatibility and lossiness report, then decide whether to buy the conversion.
