+== 2026-01-15 How To update a google sheet automatically from a CSV on github ==
+from a google search for <code>how to update a google sheet cell with numbers from a github csv file</code>:
+'''Method 1: Using the <code>IMPORTDATA</code> Function (Manual/Semi-automated)'''
+This method is the simplest if your CSV file is publicly accessible and you<br />
+don’t need real-time, automatic updates. The data will refresh<br />
+periodically or when the sheet is manually reopened.<br />
+* 1. '''Get the raw CSV URL from GitHub:''' Navigate to your CSV file on GitHub, click the '''“Raw”''' button, and copy the URL from your browser’s address bar. This URL<br />
+should point directly to the raw data and typically starts with <code>raw.githubusercontent.com...</code>.<br />
+* 2. '''Use the <code>IMPORTDATA</code> function:''' In the desired Google Sheets cell (e.g., A1), enter the following formula, replacing <code>&quot;YOUR_RAW_CSV_URL&quot;</code> with the URL you copied:
+<pre class="excel">=IMPORTDATA(&quot;YOUR_RAW_CSV_URL&quot;)</pre>
+* 3. '''Press Enter:''' The data from the GitHub CSV file will populate the sheet starting from<br />
+that cell. The data will automatically arrange itself into rows and<br />
+columns
+'''Method 2: Using Google Apps Script (Automated/Programmatic)'''
+For more robust solutions, such as updating a specific range of cells or<br />
+scheduling automatic updates, Google Apps Script is the best approach.
+* 1. '''Open the Apps Script editor:''' In your Google Sheet, go to '''Extensions''' &gt; '''Apps Script'''.
+* 2. '''Paste the script:''' Delete any existing code in the <code>Code.gs</code> file and paste the following script. Remember to replace <code>&quot;YOUR_RAW_CSV_URL&quot;</code> with your actual GitHub raw CSV URL and <code>&quot;Sheet1&quot;</code> with your target sheet’s name:
+javascript
+<syntaxhighlight lang="js">function importCSVFromGitHub() {
+      const url = "YOUR_RAW_CSV_URL"; // Replace with your GitHub raw CSV URL
+      const sheetName = "Sheet1"; // Replace with your target sheet name
+      const targetCell = "A1"; // The cell to start pasting data
+      try {
+        // Fetch the CSV data
+        const response = UrlFetchApp.fetch(url);
+        const csvData = response.getContentText();
+        // Parse the CSV data into a 2D array
+        const dataArray = Utilities.parseCsv(csvData);
+        // Get the target sheet and range
+        const sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(sheetName);
+        if (!sheet) {
+          Logger.log("Sheet not found: " + sheetName);
+          return;
+        }
+        // Update the sheet with the new data
+        // Clear previous data in the target range first if needed
+        const startRange = sheet.getRange(targetCell);
+        const startRow = startRange.getRow();
+        const startColumn = startRange.getColumn();
+        // Clear only the area the new data will occupy
+        sheet.getRange(startRow, startColumn, sheet.getLastRow(), sheet.getLastColumn()).clearContent();
+        // Set the new values
+        sheet.getRange(startRow, startColumn, dataArray.length, dataArray[0].length).setValues(dataArray);
+        Logger.log("CSV data successfully imported to " + sheetName);
+      } catch (e) {
+        Logger.log("Error importing CSV: " + e.toString());
+      }
+      }</syntaxhighlight>
+* 3. '''Save and run the script:'''
+** Click the '''Save''' icon (floppy disk) and name your project.
+** In the function dropdown menu (usually showing <code>importCSVFromGitHub</code> or <code>myFunction</code>), ensure <code>importCSVFromGitHub</code> is selected.
+** Click the '''Run''' button (play icon).
+** Authorize** the script when prompted by following the on-screen instructions.
+* 4. '''Schedule automatic updates (optional):''' You can set a time-driven trigger to run this script automatically at specific intervals:
+** In the Apps Script editor, click the '''Triggers''' icon (alarm clock).
+** Click '''+ Add Trigger'''.
+** In the “Choose which function to run” dropdown, select <code>importCSVFromGitHub</code>.
+** Under “Select event source”, choose '''Time-driven'''.
+** Configure the frequency (e.g., every hour, day) and save the trigger
