Almost, but not completely. Certain functions of common spreadsheet software are not available in GRID. These are mostly highly specialized functions or functions that are rarely used. Most notably GRID does not implement scripting languages such as Visual Basic for Applications (VBA) or App Script. Overall - however - 98% of all spreadsheets are fully supported by GRID, and for most of the rest there are relatively simple workarounds to provide the same results.

GRID supports spreadsheet files from Microsoft Excel™ (xlsx), Google Sheets™ and flat CSV data files. Users can link to these files in cloud drives such as Dropbox, OneDrive or Google Drive; provide a URL to the files; or upload them directly from their own computer.

This is a great question, and the answer is no. GRID does not write back into your original spreadsheet when a GRID document is interacted with or altered. Just think of your GRID document as a protective layer between your spreadsheet and your viewers. You decide which parts of the spreadsheet you want to present, how you want it to appear, and who will see it. The spreadsheets you’ve connected to GRID will never be altered by changes made (by author or viewers) to the GRID document.

To start collaborating on a GRID document, create a User Group. Once you’ve added colleagues to the group, group members will be able to start Conversations and leave replies for everyone to see. You’ll be able to keep feedback contextual and gather valuable ideas right in your doc.

Currently, GRID does not support co-authoring of documents. For now, each document has one author/owner.
