Excel & CSV query runner #2478

deecay · 2018-04-20T22:06:23Z

This PR adds Excel and CSV as possible datasource.

Datasource Name is the only configuration for both datasource.
Query must be in YAML format.
Specify path of excel/csv file, either local path or URI, for url parameter.
You may pass other parameters to the pandas excel/csv parsing function.

Most of the code is taken from conversion pandas.DataFrame to result and vice versa in python query (code attached) #2078, thanks to @dersphere.

Online Excel data file with parameters

Reference for parameters: CSV and Excel.

Same data without parameters (table is broken)

Need db-logo for Excel...

Thanks! Supporting both CSV and Excel is great.

My main concern with this implementation is the use of Pandas, as I always felt it's a "heavy" dependency that might introduce issues with setting up Redash for some users. Although I did look into it again and I'm no longer sure about this.

@jezdez do you happen to have any insight on Pandas requirements?

(and, @jezdez , of course it's another case for #2921 ;-))

deecay · 2018-11-20T09:39:34Z

@jezdez, any opinions? Maybe resort to requirements_excel_ds.txt?

jezdez · 2018-11-20T09:54:48Z

Yeah, installing Pandas and numpy is quite a lot for the purpose of reading and parsing Excel and CSV files alone. That's an additional ~23 MB (unpacked whl files on Linux for Python 2.7) for the Docker image and a higher maintenance burden given the high profile of Pandas and numpy for a relatively small, albeit useful feature.

Options forward:

find a different library to read and parse CSV/Excel files
ship the query runner as a separate package (Move some query runners to separate packages #2921) and document how users can install it on demand (my preference)
accept the extra dependency

A positive point is that both Pandas and numpy are available as precompiled whl files, so it's literally just a matter of downloading it.

denisov-vlad · 2018-11-20T10:06:09Z

Pandas is must have for python query runner.

Maybe it's heavy but does not require additional libraries which should be installed via apt like other datasources like mssql.

jezdez · 2018-11-20T10:11:48Z

That may or may not be so, it's out of scope of this pull request review though.

deecay · 2018-11-20T11:39:02Z

Option 2 is acceptable for me too. I will wait until #2921 is done.

xlrd will be the candidate for Option 1, but this involves decent amount of 'reinventing the wheel' to get the nice features that Pandas have (skiprows, usecols, etc). Without these features, a "perfectly formatted" excel will be required, which can be very rare as I have displayed in the examples.

arikfr · 2018-11-20T12:14:24Z

We don't have to extract all the query runners for you to be able to do this. But we will probably need to extract the query runners base classes and helper methods to their own package, so they can be used "externally". @jezdez , am I correct here?

I missed the added functionality. That's actually nice :) I would suggest a different "query syntax" though, let's use YAML here, so the query becomes:

url: https://www.unicef.org/sowc2012/pdfs/U5MR-rank_FINAL.xls
names:
  - Country
  - Mortality
  - Rank
usecols: [0, 1, 2]
skiprows: 7
skipfooter: 2

deecay · 2018-11-20T15:28:31Z

@Arik, interesting idea. I'll take a look at yandex metrica query runner first, and see what I can do about yaml.

deecay · 2018-11-30T09:44:41Z

Done with the yaml part.

deecay · 2019-10-24T12:16:59Z

Is this okay to merge now (by pymapd), since we have both numpy and pandas in our standard install?

machzqcq · 2019-12-15T17:37:36Z

Can someone confirm this is merged, reading excel and pandas df as data source will help a lot

dersphere · 2019-12-15T18:45:55Z

Would be great to have my initial code somehow integrated (thanks @deecay) :)

xsvfat · 2020-02-24T07:08:44Z

Would be great to get this merged!

jezdez

I'm sorry this never went anywhere folks.

deecay · 2021-05-26T02:13:59Z

I'm sorry this never went anywhere folks.

Hi @jezdez, what is blocking this? Or should I close this for some reason?

arikfr

Good news: we can merge this! @deecay can you please confirm this still works on latest master?

And sorry it took so long.

arikfr

Actually there are few things missing:

Logos for each one of them.
Register them so they loaded by default.
Add the local urls filtering (let me know if you need a pointer for what I mean).

Thanks!

deecay · 2021-07-24T13:27:53Z

Logo for Excel added. (csv logo was already there)
Updated init file to be enabled by default

Could you point to the local urls filtering?

susodapop · 2021-07-26T16:58:01Z

Could you point to the local urls filtering?

I think Arik is referring to this which was discussed when implementing the JSON data source.

deecay · 2021-07-27T03:07:41Z

redash/query_runner/excel.py

+            ua = args['user-agent']
+            args.pop('user-agent', None)
+
+            if is_private_address(path) and settings.ENFORCE_PRIVATE_ADDRESS_BLOCK:


@susodapop , I guess you're right. Done.

arikfr · 2021-07-27T20:27:45Z

So it took over 3 years but it's merged now. Thank you for the the continued contribution and immense patience 😅

dersphere · 2021-07-27T21:09:28Z

😃

ainsofs · 2021-09-28T04:01:56Z

CSV and Excel do not appear on my list of data sources. Is there something I need to do to make that happen? I am using image redash/redash:8.0.0.b32245 . I also tried image version 10 beta with the same result

susodapop · 2021-09-28T13:57:21Z

@ainsofs You need to run the tip of master since this PR isn't merged into the V10 branch (yet). It will be before we release.

@susodapop What do you mean by run the tip of master ? Got redash working , but CSV does not appear on the list.

@ainsofs Did you manage do get it working ? If so , please share the solution :)
