OVERVIEW
=====================================================================
UpSheet Pro is the simplest way to insert files into Google Sheets™.
Attach documents, images, PDFs — any file — directly to the cell or
row they belong to. Your real files stay safely in your own Google
Drive™, while the sheet shows a 📎 icon and highlights the cell in
yellow so everyone knows an attachment is there.

Stop chasing files across Drive, email, and chat. When you attach
files into Google Sheets with UpSheet, every document lives with the
data it belongs to — searchable, shareable, and exactly where your
team already works.

=====================================================================
KEY FEATURES
=====================================================================
Drag & drop — the fastest way to attach files into Google Sheets:
  drop any file onto a cell and it uploads instantly. Any file type
  is supported.
Table Mode (recommended) — attachments are bound to the ROW, so
  they follow your data when you sort, filter, insert, or move rows.
  Files never get lost.
Simple Mode — track attachments by plain cell reference (e.g. B5)
  when you don't need row tracking.
Attach to empty OR filled cells — your existing cell text is never
  overwritten; the file list lives in the cell note.
Multiple files per cell — keep several files on one cell without
  overwriting (up to 10 on Trial, 50 on Pro).
Search across the whole sheet — type a filename and find it in
  seconds, from any cell. Great for audits.
Share with your team — invite collaborators to a sheet and, with
  one click, let editors upload attachments too. Pro access can even
  be shared on a specific sheet.
Private by design — UpSheet can only see files it creates and the
  sheet you're in, never the rest of your Google Drive.

=====================================================================
HOW TO INSERT FILES INTO GOOGLE SHEETS — 3 STEPS
=====================================================================
1. Install — add "UpSheet Pro" from the Google Workspace Marketplace
   and authorize access (required so it can store files in your Drive).
2. Open in Google Sheets™ — Extensions → UpSheet Pro → Quick Access.
   The sidebar appears on the right.
3. Start attaching — click a cell, press Upload, drag your file in.
   The cell turns yellow with a 📎 icon. Done.

Tip: In Table Mode the system reserves hidden Column A for row
tracking, so enter your own data starting from Column B.

=====================================================================
PLANS & LIMITS
=====================================================================
Free Trial (14 days): 1 spreadsheet, up to 10 files per cell, max
10 MB per file, basic support.
Pro ($9.99/month or $79.99/year): unlimited spreadsheets, up to 50
files per cell, max 100 MB per file, usage analytics, bulk
operations, and priority support.
All plans: rate limits of 30 uploads/minute and 500 uploads/hour.

=====================================================================
SECURITY & STORAGE
=====================================================================
Files are uploaded to a single, dedicated folder that UpSheet creates
in the admin's own Google Drive — one folder per spreadsheet. UpSheet
does not store your files on its own servers. It also uses narrow
Google permissions: it can only access files it created and the
spreadsheet you're currently in, never your wider Drive or your other
sheets. To let teammates open attachments from a shared sheet, an
admin can re-share the folder with editors ("Allow editors to
upload") — avoid sharing attachment links outside your organization.

=====================================================================
TROUBLESHOOTING — CAN'T INSTALL?
=====================================================================
If, during installation or first launch, you see a page from
script.google.com that says "Sorry, unable to open the file at this
time" or "Page Not Found", this is almost always caused by being
signed in to MULTIPLE Google accounts at once (the link points to the
wrong account index).

FIX:
1. Open an Incognito / InPrivate window in your browser.
2. Sign in with ONLY the single Google account you want to use.
3. Install / open UpSheet Pro again from there.

Other quick fixes:
Menu missing or only shows "Help" → refresh the page (Ctrl+F5) and
  reopen the menu; if needed, run Re-authorize.
"Permission Required" → close the dialog, refresh, then Extensions →
  UpSheet Pro → Re-authorize.
"File too large" → the file exceeds your plan limit; compress it or
  upgrade to Pro.
