Export New Table As Displayed

Feature Requests

1

Hi all!

I'm revisiting a topic from this closed thread, which discussed the need for a feature that allows exporting table data as displayed to the user, with all mappers, filters, etc., applied. The closure of the thread might be due to version discrepancies in the table component (@victoria?), but the need for this feature persists.

In a nutshell, we're looking for a straightforward method to download table data exactly as it appears to the user. I assumed the following code would suffice, as Displayed implies what the user sees, not the underlying data:

const data = await newTable.getDisplayedData();
utils.exportData(data, 'filename', 'csv');

However, this doesn't seem to work as expected. I'm unclear about its function, especially in contrast to this existing method:

await newTable.exportData({fileName: 'test', fileType: 'csv' })

The latter method seems to apply mappings to the headers, which is counterintuitive.

For those who can access an old, legacy table, there's a workaround using a function by @Van:

function formatTablesAsSeen(table) {
  var inputData = table.displayedData; // source of data

  var inputDataLength = inputData.length;

  var headerValuesNew = table.columnHeaderNames; // new header values as objects
  var headerKeys = Object.keys(table.columnHeaderNames);

  var headerValues = Object.values(table.columns); // current header values as array

  var newHeaders = headerValues.map((val) =>
    headerKeys.includes(val) ? headerValuesNew[val] : val
  );
  var headerKeysLength = newHeaders.length;

  var outputData = [];

  var mappedColumnKeys =
    table.columnMappers == undefined ? [] : Object.keys(table.columnMappers);

  for (
    var inputDataIndex = 0;
    inputDataIndex < inputDataLength;
    inputDataIndex++
  ) {
    var outputObj = {};
    for (
      var headerKeysIndex = 0;
      headerKeysIndex < headerKeysLength;
      headerKeysIndex++
    ) {
      if (table.columnVisibility[headerValues[headerKeysIndex]]) {
        if (mappedColumnKeys.includes(headerValues[headerKeysIndex])) {
          //outputObj[newHeaders[headerKeysIndex]] = table.columnMappers[headerValues[headerKeysIndex]][inputDataIndex]
          var displayedIndex = table.displayedDataIndices[inputDataIndex];
          outputObj[newHeaders[headerKeysIndex]] =
            table.columnMappers[headerValues[headerKeysIndex]][displayedIndex];
        } else {
          outputObj[newHeaders[headerKeysIndex]] =
            inputData[inputDataIndex][headerValues[headerKeysIndex]];
        }
      }
    }
    outputData.push(outputObj);
  }

  return outputData;
}

@Kabirdas, @victoria, I'm eager to move away from the legacy table, but this feature gap is a significant hurdle. Is there any update on this being addressed in the roadmap? Do you or anyone internally see the value in this feature? Will the new table eventually match the old in this capability?

@alex-w This was solved previously, and I appreciate your backwards compatibility disposition :clap: (but we still, effectively, have the same problem... 4. years. later. :joy:)

Here's to hoping for innovative table features in 2024! :clinking_glasses:

PS: I understand there might be complexities in implementing this feature without impacting performance. A shoutout to the devs – maybe a Red Bull will give you wings to tackle this challenge! :joy: (no disrespect, I'm a dev, and this would scare me too)

I'm available for any clarifications or further discussion.

Hey @Kabirdas & @victoria,

Hope you're both doing well! Wanted to touch base to see if there's been any progress on our discussion? :see_no_evil:

heres code that worked for me with the new table. I tested opening it with Excel. it handles arrays properly. it also adheres to the accepted def for CSV RFC 4180

Hey @bobthebear,

First off, I genuinely appreciate you taking the time to provide a solution and engage in this conversation. It's great to have such supportive community members willing to help out.

I ran into a couple of hurdles trying to implement your code:

  1. When I attempt to use formatTablesAsSeen(newTable) in a JS Query, I encounter this error: missing ) after argument list. It seems like there might be a syntax issue somewhere.
  2. I also wanted to bring up a potential misunderstanding regarding the issue at hand. It appears that table.getDisplayedData() does not accurately reflect what the user sees on their end. Specifically, it:
  • Includes hidden columns,
  • Does not format the column headings as they appear visually,
  • Does not correctly format Datetime columns—at least not in my case.

These discrepancies mean that the data ready for download isn't quite what we're aiming for, as it doesn't match the user-displayed data in its entirety. This gap is precisely what we're looking to bridge.

I'm hopeful we can find a workaround or maybe refine the approach further. Your input has been invaluable, and any further guidance or suggestions you might have would be greatly appreciated.

Thank you again for your time and effort—it really makes a difference.

what do you mean by

If you can give me an example of what what it should look like or something I can fix that for you. the headings are just strings though so if you're looking for an icon or something just let me know whats missing

I fixed hidden columns. you can now specify if you want them or not.
you can also specify if you want the headers included in the csv file or not.
Datetime columns are now formatted for Excel: yyy-mm-dd hh:mm. Note: you can tell it came in to Excel as a valid date/time as it will right justify... if it comes in as a string it will left justify

formatTableAsSeen(table2, false, false);

Unfiltered (scroll down for the more polite version)

Hey @bobthebear ,

I really do appreciate you trying but we are talking past each other.

I need somebody from Retool respond.

The new table does not export the data as it Displayed to the user (full stop).

This should happen when you execute table.getDisplayedData() and formatTablesAsSeen(). Neither of these work properly.

This needs to happen. It worked with the old table, it needs to work with the new. I need to know when this will happen.

It needs to take into account all mappers, all sorts, all filters, hidden columns, column ordering, all formatting based on the data type. If it doesn't take into account something, I would like to know about it.

This is a basic requirement, if you have an API endpoint exposed, it needs to work in the obvious way. This is clearly broken.

I am not going to run this through ChatGPT because I feel like it obfuscated the true meaning with too much fluff.

Filtered through ChatGPT

Hey @bobthebear,

I truly appreciate your efforts to help, but it seems we're not fully aligned on the issue at hand.

I urgently need a response from the Retool team on this.

The core of the problem is that the new table component does not export data as it is displayed to the user. This is a significant step back from the functionality provided by the old table component, where table.getDisplayedData() and formatTablesAsSeen() accurately reflected the user's view, including all mappers, sorts, filters, hidden columns, column ordering, and data type-specific formatting.

This functionality isn't just a nice-to-have; it's essential for our operations. The ability to export data as displayed to the user should be inherent to the API endpoint's functionality. The current shortcomings represent a clear issue that needs resolution.

I'm not seeking a workaround but a permanent fix that restores or improves upon the old table's capabilities. Could the Retool team please provide insight into when we can expect a solution? Additionally, if certain aspects won't be covered by the intended fix, it would be helpful to know.

I believe in the value of clear and direct communication and hope this message conveys the importance of the issue without unnecessary complexity. I'm open to further discussion to clarify any points and provide additional feedback if needed.

Thank you for your attention to this matter.

Hi @tristdrum,

following up from office hours! As discussed, the export data functionality has an option for including/excluding hidden columns, but there are some issues downloading with the proper mappers and column formatting. We'll post here with any updates we get internally :pray: Thanks for flagging!

Can the flag for includeHiddenColumns be included on this screen?

Hey @Tess, hope you're doing great!

Sorry to be that guy, but our users are getting really sad :joy: Any hint of timelines or priority for the feature request to export table data as displayed?

Even an answer like "Trist, the odds of this happening in the next 6 months are basically 0" would be great. :see_no_evil:

Thanks a ton!

13

=/ my bad i guess. as you know this wasn't something I could fix, only retool could that so I decided to give you some code to use, if you wanted to, so you at least have something mildly working while you waited for retool instead of having a fullly broken table. most prefer to use a workaround as a temp solution, next time i'll try and make it more clear

@bobthebear I do appreciate your help, thank you :pray:t3:
