Editing documents

Once write access is enabled for a database, documents become editable.

Inline editing

Double-click a cell in the table to edit it in place. Press Enter to commit, Esc to cancel.

For anything more involved, open the document in a split pane or its own tab, where every field is laid out with a proper editor for its type.

The field editor

Firestore values are not all strings. Each type gets an editor that understands it:

• Arrays and maps — add, remove and reorder members, with nested types preserved
• Timestamps — a date and time picker that keeps sub-second precision
• GeoPoints — latitude and longitude as numbers
• References — a document path, validated
• Bytes — kept as bytes, not silently converted to a string

You can add a new field, rename one, or delete one. A deleted field is genuinely removed from the document rather than set to null.

Server-side transforms

Some changes should be computed by Firestore, not by you. These are available directly in the editor:

Transform	Effect
Server timestamp	Firestore writes the time it received the write
Increment	Atomic numeric change, safe under concurrency
Array union	Add members that are not already present
Array remove	Remove members wherever they appear

Using increment rather than read-modify-write is the difference between a counter that is correct and one that is approximately correct.

Values are never coerced

FireFetch does not round-trip your data through a JavaScript Number() or String():

• 1.0 stays a double and does not become the integer 1
• Integers beyond 2⁵³ keep every digit
• Bytes stay bytes
• Microsecond timestamps keep their microseconds

This matters most in the places you are least likely to check — an id stored as an int64, or a timestamp compared for exact equality by your application.

Copy, move and duplicate

• Duplicate a document to use it as a template for a new one
• Copy or move documents between collections
• Delete recursively to remove a document together with its subcollections, so nothing is orphaned
