In Google Docs, track changes are the function that provides you to access edits previously made by different users on different dates and time-stamp. But there may be an issue: how do we know what was done with our documents? or what changes were made to our documents? Are these changes acceptable or not? This article on how to track changes in Google Docs is best resolved for you. In other words, the Google Doc can be shared with other people so they can all, or some or one, work on the document at the same time and edit together with secure sharing in real-time and from any device. Google Docs is the collaborative potential within it. ReferenceĪpps Script Sheet Class - getRange(row, column, numrows, numcolumns).In this article, we will learn how to track changes in Google Docs. You will also have to adapt the getRange methods used in importYesterday in order to match the range of the data you have. If you also want to update yesterday's data depending on the other values, you can simply modify the importYesterday function to match your needs and/or even create another function specifically for updating the values. Next StepsĪs for the other calculations in the main sheet, you will simply have to reference the cells from the TODAY and YESTERDAY sheet. So essentially, the data is imported into the YESTERDAY sheet right before the IMPORTDATA recalculates. This is done by using the atHour(23) method which means that the trigger will run approximately at hour 23. createTrigger - which is used to trigger the execution of importYesterday function.So, in order to always get the data from yesterday, the createTrigger function was created. Note that this method above is independent of the IMPORTDATA's recalculation - so once you have all the data in the YESTERDAY sheet, it will remain there, unless you specifically trigger its change. Since the IMPORTDATA recalculates at midnight, the method here chosen to import the data makes use of the getRange and getValues to get the data and of the getRange and setValues to paste the data into the YESTERDAY sheet. importYesterday - which is used to import the data from TODAY sheet to YESTERDAY.The code above is composed of two functions: YesterdaySheet.getRange(ROW, COL, NUM_ROWS, NUM_COLS).setValues(data) Let data = todaySheet.getRange(ROW, COL, NUM_ROWS, NUM_COLS).getValues() Let todaySheet = spreadsheet.getSheetByName("TODAY") Let yesterdaySheet = spreadsheet.getSheetByName("YESTERDAY") Let spreadsheet = SpreadsheetApp.openById("SPREADSHEET_ID") So - in order to do this, you can make use of Apps Script's time-driven triggers. You could use another sheet where you will store yesterday's data. But i cannot calculate the difference without yesterday's data. The problem is that i should update yesterday's data after calculating the difference. I cannot change the source data, which is a csv imported with =IMPORTDATA I only need the difference from today's value and yesterday's value. How do i calculate the difference in "SheetA" without losing data from the day before? I do not need to keep the whole history. The difference can be negative or positive If newly imported data from "SheetB" show an increase of 7, it should display +7 in column "difference". "SheetA" has to display the daily change in respect to the previous day. | key | yesterday value | today value | difference | The data structure for daily imported data in "SheetB" looks like this:ĭata is updated every day at 00:00 CET - This means that every morning opening the spreadsheet it automatically updates values in "SheetB" with fresh data and i lose the data from the day before. "SheetB" today's data automatically imported with =IMPORTDATA(url).I do not need to track difference for more than the last 1 day. I've a spreadsheet where I've to track daily changes to a cell containing an integer value and calculate the difference between today's newly fetched data and yesterday's data.
