RETURN_CELL_INVERSED
Return a cell by position counting from the end of non-empty values.
=RETURN_CELL_INVERSED(range, inverseIndex)Devuelve: any
Descripción General
RETURN_CELL_INVERSED retrieves a value from a range by counting positions from the end rather than the beginning. Position 1 returns the last non-empty cell (equivalent to RETURN_LAST_CELL), position 2 returns the second-to-last, position 3 the third-to-last, and so on.
Parámetros
| Parámetro | Tipo | Requerido | Descripción |
|---|---|---|---|
range | Range | Sí | The range to search (e.g., A1:A100 or A:A). |
inverseIndex | number | Sí | Position from the end: 1 = last, 2 = second-to-last, etc. |

Salida
GammaCasos de Uso
Period-over-period comparison
Access the previous period value to calculate growth rate or change percentage against the current period.
Rolling average calculation
Retrieve the last N data points to compute rolling averages for stock prices or revenue trends.
Recent activity display
Show the last 3-5 support tickets or interactions on a customer dashboard by accessing recent positions.
Previous reading comparison
Compare a patient's current vital reading with their previous reading to detect significant changes.
Version history access
Access previous build numbers or version entries from an append-only deployment log.
Shift handover data
Display the previous shift's production count alongside the current shift for handover reporting.
Consejos Profesionales
Use positions 1 and 2 together to calculate the change between the last two entries: =RETURN_CELL_INVERSED(B:B,1) - RETURN_CELL_INVERSED(B:B,2).
Build a "last 5 values" display by using positions 1 through 5 across five cells.
Pair with SPARKLINE to visualize recent trends from the last N data points.
Use a cell reference for the index to create a slider-like interface for browsing historical values.
This function is invaluable when you need to access recent entries in a growing dataset without knowing the exact row number. While RETURN_LAST_CELL always gets the very last entry, RETURN_CELL_INVERSED gives you flexible access to any position from the end. This is perfect for comparing recent values, calculating period-over-period changes, or displaying a rolling window of the most recent data points.
The function first collects all non-empty values from the range, then indexes from the end. Empty cells are excluded from the count, so position 1 is always the last cell that actually contains data, regardless of any trailing blank rows.
Common applications include showing the previous day's value alongside today's for comparison, calculating week-over-week changes by accessing values at positions 1 and 8, building "last N entries" displays on dashboards, and retrieving historical checkpoints from append-only logs. If the specified position exceeds the number of non-empty cells in the range, the function returns an empty string.
Errores Comunes
Returns empty string when data existsCausa: The inverseIndex is larger than the total number of non-empty cells in the range.
Solución: Check how many non-empty cells exist using COUNTA(range) and ensure your inverseIndex does not exceed that count.
Returns unexpected valueCausa: Hidden non-empty cells (containing spaces or invisible characters) are being counted as valid entries.
Solución: Clean the range by selecting trailing cells and pressing Delete. Check for cells that appear empty but contain spaces.
Error with inverseIndex of 0Causa: Zero is not a valid position. Positions start at 1.
Solución: Use inverseIndex = 1 for the last cell. The minimum valid position is 1.
Preguntas Frecuentes
Position 1 returns the last non-empty cell in the range, which is identical to using RETURN_LAST_CELL. Position 2 returns the second-to-last, and so on.
No, empty cells are excluded before counting. The function only considers non-empty cells, so position 2 is always the second-to-last cell with actual data.
The function returns an empty string. For example, if there are only 5 non-empty cells and you request position 10, you get "".
Yes, subtract the previous value from the current: =RETURN_CELL_INVERSED(B:B, 1) - RETURN_CELL_INVERSED(B:B, 2) gives you the change between the last two entries.
Yes, the position should be a positive integer. Decimal values will be truncated to the integer part.
Yes, you can reference a cell containing the position number: =RETURN_CELL_INVERSED(A:A, E1). This lets you dynamically change which position from the end you are accessing.
Yes, the function flattens the range first, reading left-to-right, top-to-bottom, then counts from the end of all non-empty values.
Traditional approaches like INDEX(range, COUNTA(range) - N + 1) do not handle gaps in data correctly. RETURN_CELL_INVERSED excludes empty cells, giving you accurate positioning even with sparse data.
