استرجاع آخر صف بقيم في Google Sheets API v4

In the realm of Google Sheets API v4, the quest for obtaining the last row imbued with substantive content poses a nuanced challenge, yet it can be surmounted with strategic maneuvering. The API, an embodiment of Google’s computational prowess, opens a portal to the labyrinth of spreadsheet manipulation, and navigating it with finesse necessitates a discerning approach.

When traversing the sheetscape with the API, the conventional method of fetching a range becomes an instrumental precursor. Your adept usage of the spreadsheets().values().get() function, with its specified sheet ID and range, exemplifies a foundational step in the grand orchestration of data retrieval. However, the quest for the last row adorned with meaningful data demands a more sophisticated dance with the API.

To unravel this mystery, a two-step choreography beckons. Initially, expand your range to encompass the entire column of interest, ensuring no valuable tidbit eludes your digital grasp. Consequently, your range specification metamorphoses into something akin to “Sheet1!A2:B”, embracing the entire B column.

javaCopy code
mService.spreadsheets().values().get("ID_SHEET", "Sheet1!A2:B").execute();

Once the expansive data tapestry is in your hands, it’s time to perform a balletic traversal to pinpoint the last row adorned with the vestiges of information. The API furnishes a ValueRange object, an ensemble of values neatly arrayed. Leverage this to iterate through the rows in reverse order, until the first non-empty row unveils itself as the harbinger of your quest’s culmination.

Here’s a snippet to illustrate the syntactic ballet:

javaCopy code
ValueRange response = mService.spreadsheets().values().get("ID_SHEET", "Sheet1!A2:B").execute();
List> values = response.getValues();

if (values != null && !values.isEmpty()) {
    for (int i = values.size() - 1; i >= 0; i--) {
        List
